Hello guys. I was wondering if anyone can help me out here. I have a 07 2lt panel. I am having problems with the rear lift gate not opening, sunroof not working and the rear door poppers not working. I am thinking its an issue with the BCM. How and what should i be checking for. I have been having these issues for a few months now. Car runs fine and no other issues with the way it drives. The car now sits as i do not drive it much any more but i would like to get this fixed if its not going to cost so much. Looking for some insight on it. Thanks

 

Why would your first thought be the computer? Did something short circuit and cause a spark near it?

Did you check the relevant fuses and relays? The liftgate and sunroof are on the same fuse (#10 under hood).
There is a diode in the aux rear fuse box in the right rear. There are the relays in the aux under hood fuse block on the strut tower.

The cargo doors are historically problems, partly because the circuit is so complicated.

 

Wait....What ?
You have the car listed for sale in the Classifieds with the note of BCM problems. Now you're here looking for help ?
So which is it ? You want to sell it as is ? Or keep it and try to fix it ?
And. You asked about this problem 6-8 months ago but never came back to that thread.
(plus, a thread where you asked about a blend door problem and never came back to that one either)

 

 

I would do something with the hint that 2 of the problems use the same fuse.

 

And he still has not put a price in his ad.
