SOURCE: 03 GMC EnvoyXL CBM-how much and how do to replace it.

You really need to have it scaned by someone with propre equiptment. If it is a body module it will be around $500 for the part. Then it will have to be programed at a dealer. Really before you spend that much get it checked by a shop that knows computer systems. Good Luck

GM has had more that their fair share of transfer case problems. I have also seen may problems caused by addition of aftermarket equipment - especially remote starters. There is a good chance that you have a damaged transfer case, but if an electrical problem was the root cause of the damage, you will only destroy a new transfer case if the electrical problem is not resolved. If the mechanic that you are going to does not have the proper equipment and/or information to diagnose your transfer case control circuits, you should consider getting a second opinion from the dealer before buying a new transfer case. I currently work in an aftermarket shop. There are several of the GM 4 wheel drive systems where the manufacturer has not released the information necessary for an aftermarket shop to properly diagnose and repair the system. Some mechanics are simply to proud to say "I can't" or "I don't know".

Headlights only work on bright


i had this happen with my dodge ram 1500. the guy i bought it from put 350 dollar moon lit lights in with leds and they looked impressive but the issue was that they didnt go bright and i could only see 40 feet in front of me and i was sure taping led flashlights would have done me more good that those stupid headlights. then i had the idea of if the brights work and the dims dont then that means no electricity is getting to the dims so i decided to bridge the power from the bright headlight to the dims and it made all four work. now they all work, and only on bright. so im figuring there is a issue with the wiring in the truck. so this is a temporary solution if you really need just plain old lights like i did because i live out in the country

THIS KINDA COMMON ON FORGEIN CARS AND TRUCKS , SOMETIMES YOULL HEAR A CLICK AND SOMETIMES NOTHING, THIS SOUNDS LIKE A BAD STARTER, IF YOU GET SOMEONE TO HOLD KEY IN THE CRANK POSTION WHILE YOU TAP STARTER WITH A HAMMER LIGHTLY IT MAY SPIN OVER , BUT THIS DOES SOUND LIKE A DEAD SPOT IN THE STARTER AND NEEDS TO BE REPLACED, GOOD LUCK.

I have a Mitsubishi Eclipse 2000 Gt. I recently been having problems with the right headlight. I thought it it went out. So i went to auto zone and bought a new bulb. But it still won't turn on. So i tried...


Did you check the socket that bulb plugs into.I hav seen where they melt for, the hat produced by the bulb.If that isnt the issue,I would suspect the headlight switch.But first stick to basics.Check all the fuses.

I recently started experiencing electrical problems with my Chevy Prizm (2001). Basically, one morning, I attempted to start it up, and then let it run for a couple of minutes. When I lowered the parking...


This just happened to my Prizm. We found a short in a ground connector, behind the driver's side kick panel. We cut the grounds and soldered them together. That fixed the engine dying issue, but the headlights won't go off. The DRL is apparently dead. I have to plug it in when I need headlights, and then turn on the switch. I'm looking for a used DRL right now.

When I turn on the bright lights, one headlight goes out. when I turn off the bright lights, the other headlight goes out


you may need 2 light bulbs. check real close, if they go out compltely or really dim.... if dim, you have a ground wire issue, if they go out completely the bulbs are bad.

I have a 2002 buick century. The running lights will come on but the headlights will not come on. What do you think?


I have a 2000 Buick Century and if you hold the switch the brights will work but the low beams will not work not a bulb issue. The turn signals will work but still no head lights
