I'm stopped on the side of the road with my hazards on (dropping some waypoints on the GPS). Its about 115 degrees. All lights on, ac on... (no non-stock electricals tho). All of a sudden my flashers started squealing. every flash there was a nasty squeal under the dash. Like a find an extinquisher type squeal. Not sure what to make of it. This was in the middle of a 1200 mile trip so I havent seen the dealer yet. Just hoping the relay is going out and nothing else.

 

Hmmm....Sounds like a bad relay. Hopefully, that should be an easy fix.
