The door locks on my 2009 Chevy Impala are no longer locking, what could be my issue?
The vehicle's doors will not lock, by using either the key phobe or the lock buttons on
both driver and passenger door. However if I lock all the door manually both the key
phobe and the door lock buttons will open them. Also when I put the vehicle in reverse it
will no longer lock the doors either. I checked my fuse and it appears to be fine and think
if it was bad locks would not unlock.
Check your fuses and relay. If all looks good, it could be a faulty BCM. Try Ebay for a new BCM (Body Control Module) you can get one for around $70.
Thanks, I will check those out. At least it will give me a start.
It turned out to be a relay, changed it out and it is working just fine now, thanks
Aron: where was the relay for the power door lock located? Which one did you replace? This is exactly what one of our cars is doing.
The relay should be in the fuse box under the dash, passenger side kick pannel, you can't miss it
there are 3 relays,. one plugs into the box and 2 are soldered to the pcb. in the back of the box. I had a bad pcb relay. bitch to get off the board but $1.78 and a couple hours later vehicle fixed.
