Hey Kaptn, just curious, your bus wipers, are they only 1 speed, or do they not park themselves?

Hey Dan, they are 2 speed and also park themselves... We got real close to getting them to work but the way the motors are wired using only 3 wires to do all this, the control from the intermittent wiper switch (controller) wouldn't let it work right... It needs that 4th wire from the newer style park function to make it work right...

I'm not "Brand Loyal" Ford-Chevy-Dodge-Toyota I have them all, one even cross mixed...
If it Looks good and Works good then it's ok by me. Everything has its issues from time to time...
I would be real interested in hearing how you guys solve this one.
That's the bad part... the only way would be to convert it to the 4 wire style wiper motor (if possible to mount it in place)... Kaptn started to go that rout but the old ones on the Bus didn't want to let go of there happy home (parts stuck together) so he let it go and put it back together. He was able to rebuild the stock switches and got the wipers working like normal again...
You can follow the pages of stuff that we did here. http://www.fordification.com/forum/view ... hp?t=23040

Is there a part number on the relay to cross-reference?
Well were this part is located up under the dash, it's in a place that shouldn't get too dirty and should stay dry.
