Flasher relay problem

Hello,

I would cycle the hazard switch many times to clean the switch contacts. Next I would remove the trailer tow relays one at a time to see if that affects it. Here is a blinker wiring diagram so you can see how the system works. Let me know if you are not on a phone and cannot enlarge the diagrams I will send larger ones.

Here are the relay and fuse panel locations as well.

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

Cheers, Ken
