Right side turn signal switch does not work/blink?

MAKE 100% SURE BATTERY IS GOOD AND FULLY CHARGED BEFORE BLAME IS LAID.
THEY BLINK CONSTANTLY EVEN KEY OFF?
OR STUCK BLINKING ENDLESSLY KEY ON.?
OR BOTH.>????????
AND WIGGLING THE STALK (BLINK) DOES NOT FIX IT. (Mine failed once (intermittant) and remove it and put it back and runs now or 1 full year, spare in my kit never used. sigh.
NO YOU HEARD WRONG ON RELAY, THE MIP IS SOFTWARE THAT BLINKS BLINKERS.
1995 JEEP IS NOT SAME AS 2008 OR 2010.
SO DO NOT TALK TO OTHERS ON 1995 JEEPS.
OR BELOW 2005 OR ABOVE 2010; OK?
SEE HOW GOOGLING GETS LIES.?
AND SOME OWNERS ARE CLUELESS ABOUT YEARS.
the "module left control" can not be replaced by you
and is not sold new , and most be programmed.
it is dealer only fix. and super expensive over $1000
yes the stalk is easy fix. and PnP plug and play.
why not scan the PCM first see errors. i bet.

cars are complex. I have the full service manual on this car and own one too.
first tell all that works and does not work right, in brief
engine starts?
and runs and drives:?
all other lamps work, brake, park,heads?
left blinker stuck on front and rear and the dash cluster blinking too? (3 lamps to see)>>??????????

USA answer and Car only.'
left lamps only thing failing. answer.

the front located MIP, controller has 2 sub modules
for front L/R and rear L/R
ALL LEFTS FAIL, (STUCK)
or bad stalk.
after removing mine last year, and putting it back it never failed again.

just snaps off after 1 screw.

You have a body control module problem, more then likely . The BCM turns the turn signal on an off. Have a scan tool hooked up (a profesional grade scan tool ) One that can read codes in the BCM.

Turn Signal Lamps
The STOP/TURN/HAZARD fuse in the instrument panel (I/P) fuse block supplies battery positive voltage to the body control module (BCM) for the turn signal lamps. When the turn switch is placed in the LEFT TURN or RIGHT TURN position, ground is applied from G202 through the turn switch, to the turn signal switch signal circuit and to the BCM. The BCM then applies battery positive voltage to front and rear turn signal lamps supply voltage circuits. The left front turn signal lamp is grounded at G100, right front at G101, left rear at G301 and the right rear is at G302.

The turn signals are controlled by the BCM
Turn Signal Lamps
The body control module (BCM) is responsible for controlling the turn signals and hazard lamps. When the turn signal switch is placed in either the left turn or right turn position, the BCM receives a signal from the turn signal switch. The BCM then sends an on-off voltage signal to either the left or right turn signals and their instrument panel cluster (IPC) indicator. When the hazard switch is pressed, the BCM receives a signal from the hazard switch. The BCM then will send an on-off voltage signal to all the turn signal lamps. All the turn signal lamps will flash including both IPC turn signal indicators.

I would suspect a problem with the BCM or maybe corrosion in the under hood fuse box . Wires from the BCM to the front turn signals go through the underhood fuse box.
Your best bet ,take it to a qualified repair shop that has a diagnostic scan tool that can read BCM DTC'S - diagnostic trouble codes
DTC B3948 Left Front Turn Signal Circuit
The body control module (BCM) controls the left front turn signal, hazard lamp, and daytime running lamp (DRL). The BCM supplies voltage to control the lighting functions. The BCM monitors the left turn signal lamp supply voltage circuit for proper operation.

* Make, Model, Year for specific information.
* Check warranty. call for service.
*** Following is for information only. ***
* Older (Non-Computer) cars blinkers will blink faster if one of the lights are out (front and back turn signals)
* Some of the Luxury models have side blinkers and mirror lights. These will also affect the blink rate.
* Newer cars usually have a digital warning if a lamp is out; "Left Signal Error", etc.
* Turn on your lights and signal lights and have someone look around. Note; some cars won't blink or turn on unless the motor is running or the switch is in "running" mode. "AC" position does not always work. Check for lamps that are not working.
* Note that the newer cars must use exact lamp replacement or the lamp may crash the computer system. Use MFR approved parts.
* Exact replacement of older bulbs are required as they affect the speed of the blink rate. Check if the blinker bulbs were replaced with MFR approved parts.
* Check if the right type of bulb was installed. Some have double filaments for Brake and running. Blinkers are normally only one filament. But it's possible to have a double or triple lamp in really older non-standard models.
* Final, Check your battery for corroded terminals or a dead battery. Check the 2nd wire on the RED (+) lead for a good clean connection. This is the wire that goes to all the electrical system of the car. Clean and reconnect.
* Check with your dealer for further information.

sounds like flasher unit failure

Here is what the service manual says. Looks like it is not a flasher relay but a function of the body control module.

TURN SIGNAL AND HAZARD WARNING LAMP SYSTEMSystem Description OUTLINE Turn signal lamp and the hazard warning lamp is controlled by combination switch reading function and the flasher control function of BCM.
TURN SIGNAL LAMP OPERATION - BCM detects the combination switch condition by the combination switch reading function. - BCM supplies voltage to the right (left) turn signal lamp circuit when the ignition switch is turned ON and the turn signal switch is in the right (left) position. BCM blinks the turn signal lamp.
HAZARD WARNING LAMP OPERATION BCM supplies voltage to both turn signal lamp circuit when the hazard switch is turned ON. BCM blinks the hazard warning lamp.
TURN SIGNAL INDICATOR LAMP AND TURN SIGNAL SOUND OPERATION - BCM transmits the turn indicator signal to the combination meter with CAN communication while the turn signal lamp and the hazard warning lamp are operating. - Combination meter outputs the turn signal sound with the integrated buzzer while blinking the turn signal indicator lamp according to the turn indicator signal.
HIGH FLASHER OPERATION (FAIL-SAFE) - BCM detects the turn signal lamp circuit status by the terminal current value. - BCM increases the turn signal lamp blinking speed if the bulb or harness open is detected with the turn signal lamp operating. NOTE: The blinking speed is normal while operating the hazard warning lamp.

why skip RR lamp? what does IT DO? be like 1st 1st look.
dim, out, fast?

the rapid is talking to you
it means current is wrong,
shorted, or open lines. to the right.
its the wiring
if the bulbs are like 1157 brass base bulbs
why not replace them first , they can short inside,
asking online for guessing is silly, why listen to 10 examples for this.
but is cut wires.
shorted wires.
keep i mind the blinker asks funny for both opens and shorts
its a feature, that.
low current or too much.

the acid test is connect 2 TEST bulbs in parallel to the multi-function switch output right side,
blinks ok now, bingo bad lamps or bad wiring, from there to the right side.

if the hazard fails you never said????
if rigth front is dim or dead the bulb is blown or shorted
if new bulb there , then the wires are shorted.
to it.
the only help on line worth squat is how to test and use your meter.
you can, check for voltage
you can check continuity on that line (its just 1 wire)
and check for shorts on that wire to ground (lamps pulled right side to do that, lamps read 0 ohms cold)
look for collision damage RF? behind lamp sockets?
be first.
in my book.
looking is always first. sure.


I have your SM book open now, chapter 8w-50
the haz/blink module has just 2 pins, left and right out.
pin 3 on the module runs front and rear blinks, (a fact to know)
RF is BR/RD, brown -red stripe?
all comments USA on USA forum. USA car.
ok?

the right side lamp (sidemaker) only blinks turns if parks ARE oFF

Id try 2 new blinker lamps front and 1 rear.
that be first. or test the lamp on a battery , and no not get burned fingers hot wring a shorted lamp.

wish i knew
what rear did
and what both did on HAZ
out, dim or to fast.

It could be a bad multifunction (turn signal) switch. The way that switch works, it is possible that it can turn on the front blinker and not the rear one. It also cancels the brake circuit so the turn signal can work with the brake pedal depressed.

However, a more likely cause would be a break in the YELLOW/BROWN wire at the rear of the truck. It is common for the connector to get corroded at the left rear frame area where the bed harness connects to the vehicle harness. If you have trailer connections spliced into the wiring harness, these connections are also prime candidates for corrosion. I would look there first. Inspect these harnesses thoroughly all the way up and into the tail light assembly.

If the wires under the back of the truck look good, then I would check for power coming out of the turn signal switch. The wire at the turn signal switch is plain YELLOW (with no brown tracer). It is Pin (M) on the turn signal switch connector. The front signal is a LIGHT BLUE wire at the turn signal switch Pin (H). If you probe these with a test lamp, they should both work the same except the yellow wire will be hot with the brake pedal depressed and the switch NOT in the left turn position. If there is no power at the switch connector, replace the switch.

What you speak of as to the left blinker doesn't flash, yet the instrument cluster shows the green arrow (to the left), and yet that and the left turn signal lights do not flash, appears to be a simple burned out bulb. If one of your left turn signal bulbs are burnt out, then the #552 Flasher Unit in your fuse box is NOT the cause. It's the "Amperage" not being correct to the flasher unit. Place the parking brake on and start your vehicle. Put the left turn signal on and check to see ALL the bulbs are illuminated for the left turn signal. If you find one bulb that is not illuminated, then replace the bulb. It should be an 1157 bulb, but in the front it could be a 1157 Amber bulb dependent on whether your turn signal lens is clear or yellow.

If you still have difficulty finding the dead bulb, turn on the right turn signal and see which bulbs are illuminated and this will give you an idea as to which bulb on the left side isn't working, or turn on your Emergency Flashers which will turn on both the left and right side lamps and see which bulb is not lit up.

I hope this Helps,

TURN SIGNALS WILL FEED BACK THROUGH THE TURN SIGNAL SWITCH.THEY ARE INDEPENDENT OUT SIDE ON THE CAR BUT NOT IN THE SIGNAL SWITCH.REPLACE THE SIGNAL SWITCH
