My interior dome light, radio clock and power side view mirror adjusters do not work. All the fuses are not blown. I cannot figure it out.

Hello,

Can I ask if the fuses have power because if they do not it sounds like you have an ignition switch or a fusible link that is out.

Here is a guide to help us do some simple testing and figure out the problem:

Here are the power distribution wiring diagrams so we can see how the power is routed. You can see it running through the switch so test the output.

Check out the diagrams (below).

Please let us know what you find.

Cheers, Ken
