ok, well, i was modifying my corner signal lights and the side marker flasher circuit in my ICU burnt out. can i fix this, or do i have to buy a whole ICU to replace the old? where can i find the cheapest? the cheapest i found online was about 60 bucks......

 

your sure its not just a blinker fuse?

 

i think so.. none of my fuses blew out..

 

You still have a blinker switch, the hazard switch which the turn signals go through, the wireing and the ground connection along with the fuse and power side of the circuit to look at next. Do you have a wire diagram to know that the turn signals also go through the ICU?

You still have some real work to do.
