Power Door Locks

[JS45]

I have a 97 k1500 extended cab. Power locks stopped working when pressing either the passenger or driver side switch. The auto lock still works as does the factory keyless remote. I looked at the 5 different threads on power door locks but mine seems different. I watched a video of the circuit breaker and how to check that but if that was bad wouldn't the auto lock not work as well as keyless remote? Any help appreciated. Thanks

I couldn’t find a diagram for a truck, but on a two door Tahoe (it has a lock switch in the cargo area) the remote door unlock/lock receiver powers the actuators directly. It connects to the circuits downstream of the door lock switch and could, it seems, operate the locks independent of the condition of the door switch.

Door switches get power from fuse 13 (cigarette lighter). See if that’s blown.

I'll have to look at that fuse on my crew cab. The power locks on it don't work from either front door switch ( but the alarm will lock the truck!) Sometimes I have seen a fuse that looks good,the little loop appears to be unbroken, but I replace it and the thing that didn't work, now works.

yea hotwheels mine does the same. the remote works and the auto lock when the ignition gets power its just the two door buttons dont work. ill check the fuse and see if that remedies it. Thanks

Check the fuse but also test the switch to see if power going to the switch and leaving when you press the button.
