I've changed the dimmer switch. none of the lights are out as the parking brake turn signals, but none of my illumination lights are working. like my cluster lights, door, window lights, or my a/c lights. checked fuses in two fuse boxes and still haven't solved the problem.

There are two fuses I need you to check in the fuse box at the rear of the vehicle. See the attached pic. Fuses 4 and 40 power the interior lighting. Let me know if they are good. Here are a few links you may find helpful:

Let me know what you find. Also, I am assuming it is only the interior lights based on your description. Let me know if that is wrong as well as if this is a standard wheel base or long wheel base vehicle.

Take care,
Joe

I don't know how to explain but the lights on my dash that light up your speed and ac controls and window buttons aren't working. all the other lights are as in the dome when you open the door.

Hi,

Check the two fuses I indicated in the attached picture. They are the power supply for the lights you are referring to.

Let me know what you find.
