Driver side power-control won’t move right-side rear mirror

There are a few possible causes for the driver side power-control not moving the right-side rear mirror on a 1992-1999 Chevrolet Tahoe:

1. Faulty mirror motor: The motor that controls the right-side rear mirror could be faulty, preventing it from moving. This would require the replacement of the motor.
2. Wiring issue: It is possible that there is a problem with the wiring between the mirror motor and the control panel on the driver's side. A damaged or disconnected wire would prevent the control panel from communicating with the motor.
3. Faulty control panel: The control panel on the driver's side could be malfunctioning and not sending the signal to the mirror motor.

To troubleshoot the issue, you can try the following:

1. Check the mirror motor: Remove the mirror cover and test the motor using a multimeter. If the motor is faulty, it needs to be replaced.
2. Check the wiring: Inspect the wiring between the mirror motor and the control panel for any damage or disconnection. Repair or replace any damaged wires.
3. Test the control panel: If the motor and wiring are both in good condition, then the control panel may be faulty. You can test the panel by checking the voltage at the control panel when pressing the button to move the mirror.

If you are unsure about how to perform any of these checks or repairs, it is recommended to take your vehicle to a certified mechanic or dealership for assistance.

Scott Dugan your question refers to the right side mirror but in the explanation of your issue you are saying it does not move the left and right side mirror. It would help if you can clarify that for us. If it is both it could be the fuse or the switch in the control panel. Try this to diagnose what's going on with your mirror:

SIDE MIRROR

1 The electric rear view mirror~ use two motors to move the glass; one for up and down adjustments and one for left-right adjustments.

2 The control switch has a selector portion which sends voltage to the left or right side mirror. With the ig.nition in the ACC position and the engine OFF, roll down the windows and operate the mirror control switch through all functions (left-right and up-down) for both the left and right side mirrors.

3 Listen carefully for the sound of the electric motors running in the mirrors.

4 If the motors can be heard but the mirror glass doesn't move, there's probably a problem with the drive mechanism inside the mirror.

5 If the mirrors don't operate and no sound comes from the mirrors, check the Mirr/Lock fuse in the fuse block located in interior fuse/relay box, and the Htd/Mirr fuse in the underhood fuse/relay box.

6 If the fuses are OK, remove the switch panel for access to the back of the mirror control switch without disconnecting the wires attached to it. Turn the ignition ON and check for voltage at the switch.

There should be voltage at one terminal. If there's no voltage at the switch, check for an open or short in the wiring between the fuse panel and the switch.

7 If there's voltage at the switch, disconnect it. Check the switch for continuity in all its operating positions. If the switch does not have continuity, replace it.

8 Locate the wire going from the switch to ground. Leaving the switch connected, connect a jumper wire between this wire and ground. If the mirror works normally with this wire in place, repair the faulty ground connection.

9 If the mirror still doesn't work, remove the mirror and check the wires at the mirror for voltage. Check with ignition ON and the mirror selector switch on the appropriate side. Operate the mirror switch in all its positions. There should be voltage at one of the switch-to-mirror wires in each switch position (except the neutral "off" position).

10 If voltage is absent in each switch position,·check the wiring between the mirror and control switch for opens and shorts.

11 If there's voltage, remove the mirror and test it off the vehicle with jumper wires. Replace the mirror if it fails this test.
