My left headlight and tail light are both out. When I go to put on high beams the other side goes out. I checked all fuses and non are bad. What is this problem and how do I fix it?

Hello,

There is an integration module below the glove box that sounds like it has gone out but to be sure here is a guide and a wiring diagram (below) to help you get the problem fixed.

Check the system for a bad ground as well.

Please run some tests and get back to us we are interested to see what it is.

Cheers, Ken
