SOURCE: Why does my heater keep running after I shut my Envoy off?

I have the same problem. I have also been searching the web for a solution. I came across someone saying that it was the heater module located behind the glove department. I can't find now where i read this but it said the part was approx. $150.00. He was having same problem as us, heater wouldn't obey touch commands to turn on/off or when heater did blow it would only blow real low or real high. Like you, after turning off engine blower motor was still running even though it wasn't blowing air out.
I'm tired of paying for things that are not due to normal "wear and tear" on my 2003 Envoy. Let me know if this helps you and how you repaired it. I'll probably have to take mine to the shop but because I'm a "girl" I swear they think I'm crazy with all my Envoy complaints.

SOURCE: 2007 yukon xl battery dead recharged battery will

We had the same issue with our 2007 Yukon Denali XL. Died on us twice after sitting for short periods of time; once we watched a DVD with the engine off and battery died within 10 minutes. The dealership kept it overnight to troubleshoot why the battery died so quickly. They said the radio was "pulling" too much from the battery. (They supposably fixed it) But again a few days later the battery died again after sitting overnight. We brought it back to the dealership and they brought in a GMC "expert" to replace the entire DVD/CD/Navigation system. They also replaced our battery with a much larger battery, similar to the ones that GMC puts in there diesel trucks. They had our Denali for 5 days, but it appears to be fixed now.
Getting it fixed correctly wasn't without headaches, but it was all covered under warranty, including the battery. And they are updating the nav w/ the new edition disc as well for no charge.

SOURCE: tail lights not working. fuses

do the front marker/park lights work if not you could have a bad light switch on the tail light side of the switch.you need to check the brown wire at the back of the truck in the wiring harness as this is the tail light wire that feeds the bulbs.if you have power there then you will have to check for power at the socket,if no power at the socket but were you check the wire then there is a problem between the two that you will have to check out.if there is no power when checking the wire then you will have to check for lose of power between the switch and rear wiring.make sure the fuse is good by using a test light and not by looking as sometimes they look good but don`t work.

How do i reset the alarm on my 2003 Chevy Trailblazer...I can't stay my truck.


Hello Narisol,


Excerpt from the 2003 Owners Manual.


Passlock

Your vehicle is equipped with the Passlock theft-deterrent
system. Passlock is a passive theft-deterrent system.
Passlock enables fuel if the ignition lock cylinder is turned with a valid key. If a correct key is not used or the ignition lock cylinder
is tampered with, the fuel system is disabled and the vehicle
will not start. During normal operation, he SECURITY light
will turn off approximately five seconds after the key is turned to
RUN. If the engine stalls and the SECURITY light flashes,
wait about 10 minutes until the light stops flashing before trying
to restart the engine. Remember to release the key from START as
soon as the engine starts. If the engine does not start after
three tries, the vehicle needs service. If the engine is running and the
SECURITY light comes on, you will be able to restart the engine
if you turn the engine off. However, your Passlock system is not
working properly and must be serviced by your dealer. Your vehicle is not protected by Passlock at this time. You may also want to
check the fuse. See Fuses and Circuit Breakers on page 5-85.
See your dealer for service. In an emergency, call the M
Roadside Assistance Center. See Roadside Assistance Program on
page 7-5.


Excerpt from the 2003 Owners Manual.

Testing the Alarm The alarm can be tested by following these steps:
1.
From inside the vehicle, Iower the driver's window and open
the driver's door.
2.
Activate the system by locking the doors with the power door
lock switch while the door is open, or with the remote keyless entry transmitter.
3.
Get out of the vehicle, close the door and wait for the SECURITY light to go out.
4.
Then reach in through the window, unlock the door with the manual
door lock and open the door. This should set off the alarm. When
the alarm is set the power door unlock switch is not operational.
If the alarm does not sound when it should but the headlamps flash, check to see if the horn works. The horn fuse may be blown. To
replace the fuse, see Fuses and Circuit Breakers on page 5-85.
If the alarm does not sound or the headlamps do not flash, the
vehicle should be serviced by your dealer.

Hi just got 2001 daewoo leganza. test drove good paid cash get home ate lunch and went out to start the car and it cranked but would not start and run. also noticed door locks lights and windshield wipers...


Still check the voltage if it is below 12.7volts. It may be too low to have the car started. It is odd that the other electrical does not work. You may have to inspect all of the fuses then. If the fuses check out OK you may have to inspect the wiring. Check the wiring. After the battery the power cable should go to the boxes for the fuses, the relays, etc. Inspect the terminals there up to the inside. There may be some ground wires that are not connected or insulation or wires that may have gone bad.

I have a 98 Nissan altima gxe and my alarm won't honk when I lock the car but the lights go off when I lock it and Wen I take the alarm off no honk or lights go off Wat can I do


holdboth the lock and unlosk buttons on your remote simultaneously for about five seconds until the lights flash and horn chirps.that should do it.if not i believe these models used a separate horn for security system.possibly fuse for this horn is bad or the horn itself is bad.to see if this horn works lower drivers window.stand outside vehicle and lock doors with remote.wait about a minute and reach in window and MANUALLY unlock and open door(do not use power door lock button)this should cause the system to activate...horn should beep and headlamps should flash.if horn beeps try my first suggestion.if it doesnt beep and just the head lamps flash check fuses and horn for security system.

I bypassed the security system the car still want start I placed a hot wire directly on starter and the car turned over but there was no fuel going up what is the problem now


Try hooking the security system up again so that it's functional, then take out the fuse that's located on the fuse box in the trunk that's associated with the security system. It should be labeled "theft" and it's a 10amp fuse. The system will still function as normal only the horn will not sound if the security system is tripped and it will not shut down the fuel pump.

My 04 bmw ignition doest start


If it doesnot crank at all look for starter/starter relay/starter relay fuse. Most probably wiring coming to starter is loose, try to tighten it more (push towards starter). Also I would check antiteft system (if it is provided for your car) as some BMW have immobilizers.
If it cranks no start look for spark plugs, wires, distributor cap, coolant temperature sensor, O2 sensor, fueling system (fuel pump cutoof switch, fule pump relay, fuel filter).
Please kindly let me know if you need more information, or kindly provide me with more details to assist you better
Good Luck

2002 Honda Odyssey security alarm system


Make sure your hood is shut. I just got my 2002 Honda Odyssey back from the dealer today (90,000 mile check-up - I love my van and will drive it until it dies!) and when I went to lock the van with my remote transmitter, the lights didn't flash and the horn didn't sound. I open and closed all the doors and tailgate and I could hear that the doors were locked, but the security system wasn't working and that is why the lights didn't blink or the horn didn't sound. I walked up to the front of the van to check the hood to make sure it was closed (there isn't an indicator light for an open hood, only open doors) and the hood wasn't shut completely. Once I opened the hood and let it drop to securely shut, I hit the door lock button on the remote and everything worked like a charm! Hope this helps others in this predicament.
