2003 CHEVY TAHOE 2003 TAHOE INTERIOR LIGHTS DO NOT COME ON

Electrical problem
2003 Chevy Tahoe V8 Two Wheel Drive Automatic 125000 miles

The interior dome lights and door lights do not come on when the doors open. The rear dome light does not come on when I open the rear door hatch. When I use the dimmer switch I cannot turn lights on. Dashboard cluster lights work. I can manually turn on the dome lights at the switch by the light. I checked the fuses at the dome lights and they are fine (obviously since I can manually turn the light at the dome light location
