Question about 1999 Chevrolet Silverado 1500

2 Answers

Power locks and mirrors out. Driver power window out.

One day my power locks and mirrors went out in my 1999 Chevy Silverado. Neither the driverside or passenger side controls have any function. However, I am able to still lock/unlock my vehicle through my aftermarket remote start.

Also, recently my driverside power window went out. It just clicks when I try to roll the window down.

Any idea on how to fix these problems??

    Yes. All fuses look good - both under the hood and under the dash.

    I have a 99 Silverado 2500. Neither the power door locks or the keyless entry control will lock/unlock the doors. However if you push the lock button, and then open the door, the security system still alarms.

    I stopped by a GM dealership and they said it could be the actuator. Could the actuators on each side both be out? I like to fix these things myself to save money and gain knowledge, but I am stumped here.

    Any ideas?

Your chevy uses two fuses for the system. The power lock actuators are on the 15 amp fuse inside the truck. The fuse for the switches (locks and mirrors) are under the hood. For 99 to 04 (I think those are the years) there is a TSB on replacing the 3 amp fuse under the hood with a 5 amp fuse because this is a well known problem of having these blow.

Your drivers side window is a different issue. If the rest are working your problem is in the motor or getting power to the motor. The wires that go from the body to the door often crack and break with the opening and closing of the door.

I have a 2008 Chevy silverado with power locks and the driver side lock button is not working. It was previously only working for the passenger door but not the driver door, now is not working for either....

Its the switches themselves..sometimes you can disconnect the wires, then reconnect them and they might work..( I did this to mine..surprise - they worked.?.) If they do not work after reconnection.. its new switch time..

Lost power in driverside door of 2002 chevy trailblazer. Is there a certain fuse I should check?

If all that happened at once, highly suspect a broken wire harness that feeds your door panel.
I think there are separate circuits for the locks and the windows and mirror.
At the factory, I believe the doors are installed on the vehicle with the wire harnesses already in them, means they plug the door harness into a receiving socket in an under-dash harness.
I'd wonder if the vehicle had been in an accident on that side.
Be blessed.

Pull off the small triangular trim piece on the inside of the door behind the mirror. It is fastened with 3 quick connects that pop out. I won't break, but just be easy with it. After that, there are 3 nuts to remove and a wiring connector to disconnect. Reverse for reassembly.
