My hazard lights and turn signals will not work. The rear turn signals do work. I have checked the main fuses and it does not seem to be that. I am wondering what could be the problem?

Hello,

It sounds like the lamp control module is out but I would try cycling the hazard switch many times to try and clean the connections. Here is the wiring diagrams and guide to help you test the circuits and to see how the system works:

Test for power at the module. Check out the diagrams (below). Please let us know what happens.

Cheers, Ken
