'02 HD and Unimount: No low beams!

Discussion in 'Chevy Trucks' started by mr_udy, Dec 30, 2006.

  1. Ever since I've installed plow on my '02 HD, I've been having headlight problems. This time, everything is working except the low beams. Everything works fine when plow is not on but with plow (connections made), low beams no-work-o! No low beams at all...truck or plow. High beams OK. Anyone know if this is a bad relay? Thanks for any input.

    I'd start with checking the relay's first. An easy way to check them is to swap them around since you'll have two,one for low and one for high.
