Have you had the vehicle plugged into an OBD2 scanner to look for trouble codes? This will give more clues as to what this issue could be. If you have to pay for this ask at 4 or 5 places as prices can be VERY different.
Simply "throwing" parts at the problem is a Very expensive way to work. Comment below with the codes and I'll see if I can help you more.
If the right front signal light of your 2010 GMC Sierra stays on even when the truck is shut off, it could be due to a few possible reasons:
1. Stuck Relay: There might be a malfunctioning relay in the turn signal circuit that is causing the right front signal light to remain illuminated. A stuck relay can keep the circuit closed even when the vehicle is turned off. In this case, you may need to have the relay replaced or repaired.
2. Faulty Wiring: It's possible that there is a wiring issue in the turn signal circuit, causing a constant power supply to the right front signal light. This could be due to a short circuit or a damaged wire. Inspecting the wiring harness and connections for any signs of damage or loose connections would be necessary. If a faulty wire is found, it may need to be repaired or replaced.
3. Malfunctioning Switch: The turn signal switch itself could be defective or stuck in the "on" position. This can cause the right front signal light to remain illuminated regardless of the vehicle's status. Replacing the turn signal switch might be necessary if it is determined to be the cause of the issue.
To pinpoint the exact cause and resolve the problem, it is recommended to have a qualified mechanic or an automotive electrician inspect your GMC Sierra. They will have the expertise and necessary tools to diagnose the issue accurately and carry out the required repairs.
To test the ignition module on a 1995 GMC Sierra 5.7, you can follow these steps:
1. Safety Precautions: Ensure the vehicle is in park or neutral with the parking brake engaged. Also, disconnect the negative terminal of the battery to prevent any accidental electrical shock.
2. Locate the Ignition Module: The ignition module is typically mounted on the distributor or in close proximity to it. It is a small, rectangular component with electrical connectors and heat sinks.
3. Inspect the Wiring and Connections: Examine the wiring harness and connectors leading to the ignition module. Look for any signs of damage, corrosion, or loose connections. Ensure all connections are secure and in good condition.
4. Test the Ignition Coil: The ignition module works in conjunction with the ignition coil. You can test the coil by connecting a spark tester to one of the spark plug wires and grounding the tester. Have an assistant crank the engine while you observe if a spark is present. If there is no spark, it may indicate a faulty ignition coil or module.
5. Use a Multimeter: If the ignition coil tests fine, you can use a digital multimeter to test the ignition module. Set the multimeter to the resistance (ohms) setting. Disconnect the electrical connectors from the ignition module and measure the resistance between the appropriate terminals, as specified in the vehicle's service manual. Compare the readings to the manufacturer's specifications. If the resistance values are significantly different from the specified range, the ignition module may be faulty.
6. Consult a Service Manual: It's essential to refer to a detailed service manual specific to your GMC Sierra 5.7 for accurate testing procedures and specifications. The manual will provide step-by-step instructions and values for testing the ignition module.
If you are unfamiliar or uncomfortable with performing these tests yourself, it is recommended to seek assistance from a qualified automotive technician or a GMC dealership. They will have the expertise and specialized equipment to diagnose and repair the ignition system accurately.
This might help
easy as eating cherry pie.
wrong fuse there, 1amp is dead wrong, only oem size is allowed
the Reverse feed is shorted.
only where is the conundrum.? sure rear but wear.)
trailer hitch hacks top the cause.
shorted lamps sockets rear
shorted lamps did know they short easy when abused (twisted, by noobs too hard)
or LED upgrades using cheap C-H-I-N-A upgrades, that love to short at the drop of a hat, remove the upgrade that was really a down grade. BOOM
collision damage not fully cured, (endless)
some on hacked up the PRNDL switch and the R pin is shorted.
If your vehicle's air conditioning system intermittently switches from blowing cold air to hot air, there could be a few possible causes for this issue. Here are some potential reasons:
1. Low refrigerant levels: Insufficient refrigerant can lead to inconsistent cooling performance. When the refrigerant level drops, the system may blow cold air initially but eventually switch to blowing hot air. This could be due to a refrigerant leak or a problem with the AC system's components. A professional AC service technician can check the refrigerant levels and locate any potential leaks.
2. Faulty blend door actuator: The blend door actuator is responsible for directing airflow through different vents. If the blend door actuator malfunctions or gets stuck, it may cause uneven airflow distribution, resulting in cold air on one side and hot air on the other. Replacing the faulty actuator should resolve the issue.
3. Control module or sensor malfunction: The AC system relies on various sensors and control modules to regulate temperature and airflow. If any of these components malfunction, it can cause erratic cooling behavior. A diagnostic scan by a qualified technician can identify any faulty sensors or control modules that need to be repaired or replaced.
4. Electrical or wiring issue: In some cases, electrical or wiring problems can cause intermittent AC issues. Loose connections, damaged wires, or faulty relays can disrupt the proper functioning of the AC system, leading to inconsistent cooling performance. A thorough inspection of the electrical system by a professional is necessary to identify and resolve any wiring issues.
Given the complexity of diagnosing and repairing automotive AC systems, it is recommended to take your vehicle to a qualified mechanic or AC specialist. They have the necessary tools, knowledge, and experience to diagnose the specific issue and perform the required repairs to restore consistent cooling performance in your truck.
no car told. year 2000- but no truck told. at all
C7500? what, over 20+ cars that year GMC actual
the answer always simple
buy the service manual and read that.
you posted ANON so I cannot see all your posts to glean model name,
my guess Transfer case motor drive. device. fuse./
the is no answer 20+ cars ever.
2992 , ARE YOU CAPTAIN KIRK, TRAVELING 969 YEARS IN TO THE FUTURE OR MICHEAL J. FOX?
CAN I WATCH? LOL !!!!!!!!!!!
2002 SURE.
xl 1500 OR XL 2500 WHICH IS IT?
engine starts and drives? sure as RPM guage works.
ALL FUSES GOOD IN ALL BOXES ?????????
YOU CAN NOT DO THAT.
THE CLUSTER IS NOT PLUG AND PLAY AT ALL IN THE USA
THE CLUSTER AND PCM ARE MARRIED FOR ODOMETER LAWS.
but oddly not this truck , IPC is master of ODOM it seems.
MY GUESS IS BOUGHT THE TRUCK DEAD LIKE THIS.
HOW KNOWS WHAT OTHERS DID, ENDLESS AND BAD.
ABS NEEDS ITS OWN SCAN WITH A REAL ABS SCAN TOO,.
ABS FUSE BLOWN 60AMPS
IP BOX AIR BAG FUSE BLOWN. 15AMP
THERE IS NO OTHER WAY, IF PCM WILL NOT SHOW ABS STATUS.
SAME WITH SRS BAGS IT MUST BE SRS SCANNED.
IS ODOMETER IS DEAD ?
DO NOT IGNORE SHORTED 02 SENSORS, THEY LOVE TO.
AND IS SUPER BAD FOR POWER BUS BUT There are 2x, 02 fuses.
the cluster uses RADIO FUse 15amp under hold box
cigar fuse not blow or scan port fails at pin 16.DLC obd2.
this truck is complex ,lost of things to short out fuses are FIRST
all of them checked first, a 20cent fix each one found.
saving endless labor. barking up wrong trees, (pun intended)
Cluster facts. real name GM IPC
3 fuses.IN IP box AND 1 IN HOOD BOX.
cruise,IGN0, IGN1 all good and radio fuse (hood) good
if radio blows the info display goes dead."MESSAGES"
G103 ground to IPC good
the cluster is 99% pure digital and runs off serial data from pcm and more, the 1% are some simple lamps
Turn sigs
CEL is PCM controlled
100 $% digital Odometer and trip, display
no why that works with IPC swaps
hints from the web
Mileage in full size trucks is kept only in the IPC, instrument panel cluster. The Colorado and
Canyon are kept in the BCM..
the rebuilder said
VIN/mileage required to order!
SO IT SEEMS THE IPC IS MASTER OF ODOM AND TELLS THE PCM MILES
BUT VIN CODES CAN BE PROBLEM STORED AND NOT EQUAL.
is this a preSALES question or post installed. or what?
or post intall and lost a FOB? tell the full story here, we can not guess.
what is this Python thing (a aftermarket remote start kit)
ask GM this?
most cars this new the manual states that 3rd party remote starts will not work
ask GM first.
some sellers flat out lie to get money and know many customers
will not return the unit or say there is no warranty
many states now this down grade is *******.
the makers online help is useless (faq) but is because of extreme complexity here(vast cars and years and models)
the answer is call them on a phone or ask the authorized installer Python.
all modern cars have and IMMO and this IMMO PASSKEY
will not like any kind if bogus remote starts.
the modern car used very complex rolling codes
that are kept secret, even by law now.
ask them?
https://pythoncarsecurity.com/Products/
one of the most complex topics on any modern car
10x that with IMMO
OK NOW A SYMPTOM. CRANKS BUT WILL NOT STARTkey is bad,IMMO lamp glowing telling you the key is bad.do you have 5 pound key chain that wrecks all car locks? my guess no but the battery in truck is low underhood, 12vdc,car has Throttle Actuator Control throttle by wire and will not start or only idles or limits speed to 20mph if it fails TBW, TBW (TAC) has many failure modes and one is not to drive over people if Throttle pots (x4 )say its at WOTwide open throttle. or the silly motor fail and is jammed i the TB throttle body.there are 50 causes of no starts.and up to 20 tests to find it using real tools.guessing 49 times is costly.I never pull any pump on a whim and take bath in fuel the pump tests are easy on car ask.the PCM cuts fuel for many reasons, 6 at least.IMMO tops the list.fuses blownlean the PCM now,. do not fail to scan any modern car or go broke fast or have huge down times and piles of wasted labor or worse add wrong or bad parts or not calibrating them first. per service manual...SCAN ITI CRANK IT AND AT STALL i SCAN IT. NOW, KEY STILL ON AND THE DTC'SROLL OUT , MOST THE TIME.
are you confused,????? its not a GM./

THE SERVICE MANUAL SHOWS THIS DECODE FULLY.
BIT BY BIT.
OR HERE
https://www.youcanic.com/toyota-vin-decoder/position 12 " 17 identifies the serial number of the car.
wow no year car told. now that is a Hard row to hoe.. 2007 to NOW.
no engine told and cats are designed for engine and smog ,in one countries laws.
reset the all DTC errors via button on scan tool;
then drive see if P0420 comes back, first
not buy $400 cat on a whim./
I roll the dice, see 10, 2010
and answer. and LY7 engine V6 (there are others)
DTC P0420: Catalyst System Low Efficiency Bank 1
DTC P0430: Catalyst System Low Efficiency Bank 2
bank 1 means , that bank that contains cylinder #1
where is cylinder #1 it on all V engines, that cylinder that is MOST forward.
all cyl 1 are offset front
never post about cars and no year or engine told or post #8th digit of VIN this is engine code, so answer and be correct. (USA answer me only)
If it has a distributor you will want to make sure that it is in time. If the ECU cant find the cam signal it doesn't know when to fire the coil. I have ran into this more tha once on that year truck.
no year car told, no engine told and is a pure engine/EFI question.
a minute not 10second and dies,
the dash IMMO lamp must not be unhappy or the engine is immoblizeds in 1 to 10 seconds. most cars or dead totally others.
well , there are 50 causes or stalls on all engines
we do up to 20 test using 10 or more tools to find real cause. guessing 50 times , no shop does that .
can take the line and put in a can of gas it will run????????? HUH?
this means test fuel works? sprayed into the intake
and runs means it runs for 3seconds on test fueL and stalls/
we cant see your acts there, Impossible. too.
here is the order (pure physics Otto cycle gas engine) ASE rules( books/training)
engine must be good. (compressing tests pass and test fuel works.)
spark must be good. if is test fuel works and and runs for 3 second
is all a good sign
then last is fuel all above ok testing
fuel pressure must be at spec, no car told SO can not look that up.
sierra what is it and year.
Chevrolet C/K C1500 pickup or k = 4wd or ) what engine, lots of engine,
Chevrolet Silverado
Chevrolet Suburban
top fix any car engine learn what is under hood first
the RPO codes tell that. and VIN .
by year
Is the check engine light on, or yellow wrench light symbol? Hook up a professional grade scan tool an check for DTC'S - diagnostic trouble codes . No throttle response , problem with electric throttle control . Two position sensors in gas pedal assembly - two position sensors in the electronic throttle body - plus a DC motor to control throttle plate position. Other poster has no clue. Dirty throttle body would not cause no throttle response, rough or unstable idle for sure.
