2nd Gen Non-Engine/Transmission Hazard flashers don't work

[RyanStewart]

I lost my hazards pulling a trailer a while back and I haven't been able to figure out whats wrong. I've replaced both flasher units and checked every fuse, still no hazards. Any idea where to look next?

Does yours have the trailer towing package with the relays for various trailer functions?



This happens to me, every now and then, mostly with signals: The flasher pins come loose, but the flasher is still in its spot. I have has to very slightly twist the flasher pins using two needle nose pliers to maintain contact.



Probably not what you have going on, though.

I'll check that, but I think its got something to do with the trailer I hooked up. We rented a tractor, and the trailers they used were kinda rough. Blew a few fuses with them, but this time its not the fuse, and I don't know where to look. I do know I lost them pulling a trailer though.

This happened to mine. I changed the relays to heavy duty relays and everything is fine.

I found it. I didn't realize there are more fuses under the hood in the relay box. One of them was blown. Now I just gotta find a big 15 amp fuse (all I have is the mini ones for the main fuse panel )

Hey Ryan, hope you figured everything out, but thought you might like to read this. A while back, i was losing electrical power and blowing fuses like crazy. Found out my trailer connector under the bumper was causing all the problems. Cleaned about a pound of mud out of it, put it all back together, and everything was fine. A few weeks later, i towed a trailer around all night, no problems, i was thrilled. The next day, i went to start the truck, all the fuses blew as well as the starter. Replaced everything, as well as unplugged the trailer connector, and haven't had a problem since. Haven't replaced the connector or hooked the old one back up yet..... Might help you, apparently they act a bit weird
