Strange power lock issue.
Bought the wife a 2007 cobalt LT 2.2 from day one the remote would never unlock the door, only lock it. We figured it just needed to be programmed properly. Naturally I tried to reprogram the remote inside the car using the manual power lock buttons on the doors and here is where it gets weird.
The power lock buttons do not work on either passenger or driver doors(2 door) there is literally no response when pushing lock or unlco. I decided to check the fuses but they were fine. I even replaced them just in case. It's worth mentioning that the trunk cannot be opened from inside with the button inside the car.
Putting the car in drive will lock the doors automatically. Putting the car in park unlocks the doors automatically as intended.
So to sum up my thoughts. Fuses are fine. The power locks are working when car is put in drive and unlock when in park sounds like it's not a motor. So somewhere in between something is not working properly. I read that it could be the BCM but I figured that it would work or not work not just work partially. If anything maybe it would be sporadic. Also the car came with one key and one remote, we are unsure if the remote is the original.
Anybody have any thoughts or insight on this issue? I figured someone here could maybe have an idea of what exactly could be going on.
Thanks in advance.
