Hi All,

I have a 2001 F150 5.4 supercab, the wipers and washer fluid pump stopped working after an aftermarket headunit was installed.

So far, I put a new, good wiper/turn signal switch. The turn signals and hazards work. I tested the fuses under GEM module and fuse 11 has power when on or acc and all other fuses look good. I swapped both relay wiper high/low relay and the wiper run/park relay under the hood with good relays and still no wipers or washer fluid.

I am going to try to jump and test the power going to both relays under the hood tonight but is there anything else I am missing that is under the dash or could be related to the stock radio being swapped out to aftermarket. Like said, fuse 11 in the cab has power when on or acc so I don't think its power issue in the cab part but else where.

Thanks,

Alan
