Hi Group!

I read in many forums that the possible cause could be the BCM.
After checking the fuses and light bulbs I went ahead and bought a used BCM.
I installed it but the problem persist, now I put my original BCM back in the car.
I'm not sure where else to look.
Please help.
Thanks!

Hello,

Lets start by making sure there is power at the stop and hazard fuses. here is a guide to help you, the key should be on before you begin. Also I have included the fuse location and the blinker and hazard light wiring diagrams so you can see how the system works.

Check out the diagrams (below). Please let us know what happens.

Hello group,

I went and got another continuity tester and tested the fuses again and this time the hazard fuse did not work.
Learning lesson: Use more than one tester.
