    Default Power locks on 2000 Sliverado

    All,

    I need some help in where to start troubleshooting issues with the power locks on a 99 (2000 bodystyle) silverado.

    Neither power door lock works. I can manually lock and unlock both doors just fine. when I press the L or U I do hear the relays click in the fuse box. I have the covers off of the fuse boxes and have checked all the fuses that I figured were part of the power locks....

    So I am not sure where to test.. I have the door pan off. I see I have 3 elec plugs that go to the door lock assembly. One of the plugs has 12 volt on it. It does not change when the L or U is pressed. One plug is for the door buzzer and the other one I assume is the switch... I am not sure how to test that?

    Can you guys help?

    I want to know the answer to this one too. I actually bought a left and right lock actuator online (delco) at $85 each (dealer was $170 each) and replacing that did not fix it in my 2000 Silverado. Exact same symptoms. I also checked the fuses and relays.

    Your truck may need to relearn the receiver you can find the instructions online it's really easy to do usually.

    That's kinda funny, I have the opposite problem. I can't get my doors to lock manually, but my power switch works...

    That just means the switch is probably dead or improperly connected. Check the connection and check if power is getting to the switch may require taking that part of your door apart.
