None of the lights are working in the rear. Started with drivers side blinking fast so checked and not working replaced both bulbs and started working. That was two days ago. I drove today and the right side started blinking fast, when I checked so was the left blinker. I checked the lights, brake lights, blinkers and hazards and had nothing. I replaced bulbs again and fuses that were related to back lights. I also replaced the electronic back light (EBL) relay. Got nothing. Any suggestions? Thank you!

Hey PENKILLEEN@GMAIL. COM,

The only thing I can see shared by all of these lights is the ground connection.

Do you have access to a test light or multi-meter?

If so I can run you through checking power/ground.

The ground location is behind the left rear quarter panel.

There should be multiple wires going into this ground connector.

You could start by checking this ground connection for corrosion/tightness.

Hope this helps, let us know how you go.

Regards, Joe

Hello,

It sounds like the BCM could be going out. but to be sure here is a guide to help test the power and grounds with the blinker wiring diagrams so you can see how the system works below:

If the BCM is bad you will need to get it programmed which should cost about 130.00. Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.
