Hi, my name is***** fuse 22 in the main fuse box under the hood. That fuse powers the combination switch for the turn signals and wipers and headlight flash.

Expert:  Marty replied 6 months ago.

Ok, fuse 22 powers the pink/black wire at the combination switch connector. Make sure you have power there as well with the key on.

I CAME BACK THE FUSE HAS 12V NOW I HAVE TO GO OUT AGAIN TO CGEAK PINK / BLACK WIRE PLEASE WATE
Customer: replied 6 months ago.
NO POWER TO PINK/BLACK WIRE
Expert:  Marty replied 6 months ago.

Well that's the problem. Now you need to trace the wire back in the harness until you locate the break in the circuit. Replace fuse 22 with a new fuse just in case there is a problem with the fuse. Next step would be to check various points in the harness with a sharp probe.
