I have a 2003 2500hd crew cab. As soon as I shift into gear, the driver info center chimes in right rear door ajar when it clearly is not! After many hours chasing down wiring with no luck i took it to the dealer. They diagnosed it with needing a new Body Control Module. Since they want nearly $500 to install this I decided if anyone has had experience with installing a new one on their vehicle?????? Any help would be greatly appreciated!

Thank you

 

It's not so much the factor of installing it, it's flashing the pcm afterwards so that the computer recognizes it

 

Usually they can reflash the one you have. I just had mine done in the 2003 Tahoe. IMO from 2003 and up GM got too fancy with these damn trucks. We had a 2002 Yukon before this and it was MUCH simpler. I still can't figure out the A/C controls completely.

 

I was afraid that may be the response... I will be pretty P.O. if they install a new BCM and say, "well gosh that didn't fix it, I guess we'll just have to put a new motor and transmission in. Do you want to get that done today or schedule another appointment?" Not to that extreme but you catch my drift. I think i'm just going to put the body on a 88-98 box style frame so I can still work on the darn thing. Thanks guys.
