As the title states, I am still having problems with my wipers and I am not really stumped. Before I was having the problem that my delays didn't work and that if I used the washers then the wipers wouldn't stop running, it had been doing this for about 2 yrs. I was told that the problem was the wiper control module. Also the wiper motor started to make alot noise over the last 6-8 months. So I finally found a scrap yard that had both the motor and the wiper control module, also out of a 94 F150 and I they said that motor didn't make any noise and the delays were working in the donor truck.

I just got in from putting the "new" module in and now I have delays, but only when it wants to work but low and high speeds are also working only when they want to. And the wipers don't always return to the home position, they stop about 1/4 of the way up the windshield, hold there for about 40 secs then drop to the home position. I put the original module back in and it does the same thing.

What the hell is going on with my truck?? Any suggestions are welcome, if you need more info just let me know.

 

I was just outside looking at the truck again. I have swapped both modules in and out and it does the same thing no matter which module I have in the truck. I am also not hearing the clicking sound that I used to then turning wipers on/off and switching the delays. Could it be the switch that is causing this?? Thats about the only thing that I can think of. HELP!!!!

on edit: the washer pump doesn't run with either module installed.

 

Someone has to have some idea.

 

try this?

Most likely related to the multifunction switch (turn signal switch). Try messing with the switch itself when acts up. I need to replace mine on my 92 and 94 trucks.

 

I had a problem with the wipers on my 92. Every time I had the wipers on and turned on the blinkers the wipers would quit working. Also I had the problem with the intermittent wipers. They would go whenever they fealt like it. I replaced the wiper/turn signal switch and its been great ever since.

 

dont know if this will help you,but my 97 150 had wacky wipers some times on or off they would do what ever, long to short . my switch is on sig post (took apart,cleaned with contact cleaner put dielectric grease on contacts and put back! vawola! the contacks were dirty and gummed up with grease. no more.hope it helps
