1994 f250 wiper problem

I just bought this truck so I don't know alot of history. I tried to use my wipers the other day and they didn't work. I looked in my fuse box and it says it needs an 8.25 c.b. I didn't have one at the time so I put in a 20 just to see what happened. The wipers worked but only at one speed and they wouldn't turn off. Any suggestions would be greatly appreciated.

Thanx

This diagram has your wiper circuit in it.

Funny it doesn't show a circuit breaker, but shows a fuse. Anyway, if the wiring looks ok, and I had to guess, my guess would be the multi-function switch or the plug going to it is loose and or melted. Do your turnsignals work ok? This is switch has a lot of stuff in it, and is always giving trouble.

its wierd the back of my fude cover says ci.b. but my manual says fuse. I have tried both and get the same outcome. my turn signals work fine. I pulled it apart today and the plug looks ok as does the wiring. as far as I can tell everything looks just fine. could it be that the switch has gone bad?

If you have a voltmeter, you could do a little testing using the diagram to see if the switch is bad.

The wiring diaagram shows the hot wire going to the wiper control module. This may be your problem, not the switch. There are relays in this unit that may be shorted out. The wiper module is located behind the glove box. You push in on two tabs and the unit slides down out of the mounting bracket. This unit cost over one hundred bucks at the dealer (check salvage yards). I had a problem with my delay wipers and had to replace this unit.
