Wipers Dead
2001 F150 5.4L 4x4
My windshield wipers don’t work. The trucks been sitting for a few days, so I don’t really know when they worked last, or why they’ve gone out.
Fuse #11(30A) is OK since the washer fluid pump works. I don’t hear any attempt by the wiper motor to run, not even a relay click (dead quiet). I believe there’s something wrong with an onboard computer somewhere because with the key in the accessories position and the wipers switched on, the ABS idiot light in the dash comes on. Also the hood courtesy light doesn’t light anymore, but that same ABS idiot light in the dash comes on when I pop the hood. I tried disconnecting the battery (and turning on the headlights to bleed any residual voltage down), in an attempt to reset the GEM, but the problem remains. Mirrors, door locks, power windows, etc. all work OK. It's just the wiper motor isn't getting the instruction to run under any circumstance.
I’ve seen some posts about some kind of housing switch defect, maybe this is my problem:
Defect Summary:
VEHICLE DESCRIPTION: PASSENGER CARS, SPORT UTILITY VEHICLES, AND LIGHT AND MEDIUM DUTY PICKUP TRUCKS. A SWITCH LOCATED IN THE PLASTIC COVER OF THE WIPER MOTOR GEAR CASE COULD MALFUNCTION AND OVERHEAT, POTENTIALLY RESULTING IN LOSS OF INTERMITTENT WIPER FUNCTION, LOSS OF WIPER PARK FUNCTION, COMPLETE LOSS OF WIPER FUNCTION, OR IGNITION OF THE PLASTIC COVER MATERIAL. SWITCH MALFUNCTION IS MOST LIKELY TO OCCUR WHEN THE INTERMITTENT SETTING OF THE WIPERS IS BEING USED, OR WHEN SNOW OR ICE OBSTRUCTS THE BLADES FROM RETURNING TO THE "PARKED" POSITION AT THE BOTTOM OF THE WINDSHIELD. THESE VEHICLES WERE BUILT AT THE FOLLOWING ASSEMBLY PLANTS: ATLANTA PLANT FROM 2/11/00 THROUGH 7/31/00; CHICAGO PLANT FROM 2/14/00 THROUGH 8/4/00; KANSAS CITY PLANT FROM 2/26/00 TO 9/4/00; KENTUCKY TRUCK PLANT FROM 2/18/00 TO 8/31/00; MICHIGAN TRUCK PLANT FROM 2/23/00 THROUGH 8/3/00; NORFOLK PLANT FROM 2/21/00 THROUGH 7/27/00; WAYNE STAMPING AND ASSEMBLY PLANT FROM 2/25/00 THROUGH 8/15/00; AND WIXOM PLANT FROM 2/15/00 THROUGH 8/8/00.
I’m not sure what to try next and I want to take a trip this weekend.

Well the relay actually is clicking when the wiper switch is turned on. I swapped out the relay with the one right next to it just to see if that was it, but still no worky. So maybe it's the wiper motor. Guess I'll do some searching about wiper motor R & R.
