I have a 1997 Z71 PU and all the sudden both automatic door locks quit working at the same time. The key fob will not open and close the door locks and the automatic door button inside will not lock the doors, you have to manually lock them. I checked the fuse on the drivers side panel inside, per the manual, it was fine. Is there anything else I can check? i.e. relay, solenoid? Thank you in advance for any help....

there is a relay under the dash somewhere that i have not been able to locate so far,my power locks dont work either and when i hit one of the lock/unlock switch, i can hear the relay clicking under the dash but i have a feeling that im going to have to pull apart the whole dash again to find the dang thing, does yours click?

 

No, I was just out there looking for some kind of relay under the dash and no click when I hit the button.

 

if neither work then id be suprised if both motors went out at once, could it be wiring issue?

 

I have the same problem on my 2006 Uplander. Door locks stopped working. Checked the fuse and its ok. I also hear a "click" when I push the door lock button and suspect its a relay under the dashboard somewhere. I took the bottom panel of the dashboard off but could not find the relay, but could hear the "clicking". It can't be actuators because none of the doors work and can't believe that all the actuators went at the same time. I hope its not the BCM. Someone, please tell me its not the BCM.

Thanks.
