Powered mirrors not working

If the side mirrors on your 1999 Chevy Tahoe are not working, there are several things that could be causing the issue. Here are a few things to check:

1. Check the fuse: The first thing to check is the fuse that controls the side mirrors. The fuse box is located on the driver's side of the dashboard. Look for the fuse labeled "Mirrors" and check to see if it has blown. If the fuse is blown, replace it with a new one.
2. Check the wiring: If the fuse is not the issue, the next step is to check the wiring. Inspect the wiring that leads from the mirror switch to the mirrors themselves. Look for any signs of damage, such as fraying or exposed wires. If you find any damage, you will need to repair or replace the wiring.
3. Check the mirror switch: The mirror switch could be the issue. Use a multimeter to test the switch and make sure it is working properly. If the switch is not working, you will need to replace it.
4. Check the mirrors: If the mirrors are not responding to the switch, the problem could be with the mirrors themselves. Check the wiring that leads to the mirrors and make sure it is not damaged. If the wiring is fine, the mirrors may need to be replaced.

In general, electrical issues can be difficult to diagnose and repair, so if you are not comfortable working on your vehicle's electrical system, it may be best to take it to a professional mechanic for repair.
