Hello,

Vehicle listed above is a Limited, daily driver. Turn signals and hazard lights stopped working, no clicking, no lights, no sound when engaged.

Replaced the fuse. Replaced the flasher relay. Replaced the turn signal switch.

The turn signals and hazards still do not function at all. The old and new turn signal switches work fine for turning the headlights and bights on.

I was told that there is power going into the old turn signal switch, but no power coming from it. I had to take the car back from the mechanic who told me this without anything being fixed, then replaced the switch myself. Still nothing.

Any advice on where to go from here would be very much appreciated. I do not own a multimeter.

Thank you.

You will need a test light to check for power, which is very inexpensive.

Here is a guide to help you see how to use it:

With it you need to check for power at the TURN fuse in the driver side fuse panel and also the TAIL fuse in the under-hood fuse panel. If they have power on both sides

There is a TAIL and integration relay that need to be checked for power as well.

Here are the wiring diagrams and the fuse and relay locations in the diagrams below. Please let me know what happens.
