K1500 - 1993 - 2 Door - Door Lock Issue

My electric door locks just stopped working.

I doubt its the actuator since the passenger side doesn't work either. Checked fuses and no issues there.

Anyone have a suggestion?
Help, as always, greatly appreciated.


D.R.

 

I'd check the relay next. You should have another relay from a working accessory to swap out to determine if it's the problem. Power window relay maybe.

 

OK, so where are the relays located?
