Just dug my truck out of the woods to use as a plow truck, I got the plow mounted OK and brought it out today and found that when I turn the wipers on the brake light comes on with a buzzer and no wipers. I know that the mice have been living in the engine compartment but I didn't see any sign of them in the cab. Has anyone have any ideas where to look first. Thanks

 

Look for wire damage everywhere.
