Hello,

Yes, that happens, the lighting control module is shorted out due to a voltage spike. Here is the location and the interior light wiring diagrams so you can see how the system works.

The lighting control module is located under the dash.

Check out the diagrams (bbelow).

Let us know what happens and please upload pictures or videos of the problem.

Cheers, Ken
