Courtesy lights do not come on until starting car but do not go off until stopped shut off and ten minutes. Also, noticed door seems to try and lock or unlock while driving.

Hello,

This sounds like a bad door light switch which I would test using this guide and the interior light wiring diagrams below. Test for ground.

Check out the diagrams (below).

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

Cheers, Ken
