Hello,

It sounds like the flasher stopped working but to be sure. Here is the blinker wiring diagrams so you can see the way the system works and a guide to see where you lost power:

Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.

Cheers, Ken

Can you cycle the hazard switch many times to help clean the connections in the multi function switch? Can you test the light green and white and white with light blue coming out of the switch? It sounds like the switch is bad.

When I test the white with pink wire my tester is flashing, but when I test the blue with orange wire my tester just stays on but not flashing. I tested the plastic connector coming from the harness. Don't know what to do next. The wires that I tested, do they have anything to do with the turn signals?

Sorry you need to test the light blue wire coming out of the flasher relay to see if that blinks or has power

Yep the multi function (hazard) switch is bad did you try to cycle the switch back and forth a bunch of times to clean the contacts? (Hazard switch off and and on) give that a try first it should have power out of the light green and white wire but it wont if its bad.

I found the problems. I put a jumper on the gray/yellow and white/pink wires on the ignition switch and that took care of the turn signals ABS, brake, and airbag lights staying on all the time. My A/C started working also. Thank you anyway for all your help.
