2007 mitsubishi galant head lights are coming on after i park and lock up car and go to bed. They will turn on by themselves a little while after i go to bed. When i come out in the morning for work it is completely dead and i need a jump. I took it into a shop and they said that they couldnt figure out what was wrong with it but i would need to leave it for a few days which i work 2 jobs and go to the Dr. 5 days out of week so im hoping i can find some help on here to fix it

Thank you for writing in. The issues you are having could be difficult to diagnose without investing some time. The switch for the headlights could be to blame, as well as the electronic control module that controls it. Both of these will need to be tested and repaired if faulty. When it comes to the time it takes for diagnostics and repairs, it may take longer than you are willing to part with your vehicle. You may want to find a shop that can loan you a vehicle while they perform tests and make the proper corrections. Good luck!

Electrical / wiring problems can be the most challenging to diagnose and fix.  The shop needs time to recreate the problem in order to trace it to the root cause.  It could be the headlight assembly, could be the wiring, or it could be the car's ECU.  A mechanic who has expertise in electrical diagnostics and the necessary tools (like a good volt meter) needs to look at it.  Not every technicial has those skills, so be sure the shop has a qualified diagnostician working on your car.
