Hey all! New to the forum here. I have a 1994 sierra. Is there a relay somewhere for the wipers? I think the problem is in the signal lever itself but I could be wrong hopefully! Sometimes when I go to use the wipers nothing happens when I twist the ****. And if I leave it in the on position, sometime in the future it will just start working. And then the delay works erratically, meaning that the speed positions aren't working right. Any help will be appreciated! Thanx! Paul.
