1994 F150 Wiper Circuit Diagnostics?
Alright......nearing the end of my frame off rebuild.
It's an F150 302 1994.
Anyhow. All harnesses back in. Battery hooked up.
Symptoms. No wiper function at all.
Nothing. All other eletlctrical functions run ie lights, radio, blower motor, starter, everything.
What happens is with the ignition in ON position when I turn the MFS to Low and any position all the way to High, I'm just getting clicking in the Wiper Module and a creaking sound. I have swapped my spare module in, I have dissassembled my MFS and confirmed it solid. Also plugged in my spare MFS, also plugged in my spare wiper motor. Same symptoms even with all 3 replaced in the circuit. The fuse in the cab is solid. I even swapped that with a spare.
Does anyone have the full diagnostic procedures for the wiper circuit complete? So I can narrow this down. Its driving me nuts. Other than this I'm ready to fire the bitch up lol
