I have a 1998 Chevy Lumina LS that has power door locks with remote. All lock and unlock functions from both the remote and the inner buttons work, but the auto lock\unlock when the ignition is turned on/off has quit working. What do I need to look for?
Check fuses and relay first. Then you'll need to see if the unlock/lock button is gettingpoer and if it's going through the switch when you hit it.I'd bet it's not. If it is it may be the module is screwed up and you'll have to have that checked as you can't, you need a computer to do that.
