Sticking push pin switch in door mount pillar, driver side. ( Down by your left knee, door hits it and shuts off interior lights and radio ect when it closes.) Cheap switch all plastic made gets sticky and stays in so your radio and lights inside won't shut off until it decides to press out. Oil may or may not help. Try oil first.

Solution in my case. $20 switch from Advance Auto. Old one just pries out with a screwdriver. lift tab lock on switch back and remove clip, push in new one. About the hardest thing in doing this is not dropping the wires back into the switch hole until you are done. Make sure the clip clicks in place so it doesn't fall off. No mechanic needed for this job its so easy.
