94 B4000 Wiper problems
Well I have the Tranny fixed and the MAF changed. Now the wipers will not work on low intermittent or park. Anyone have any ideas?
I think it is the Control Module butam not sure. If it is is there a way to wire around it for low and park? Living in WA with out wipers is not a option.

I have the problem figured out. With my trusty manual and electrical drawings I went digging today. Found the control module after taking dash apart. I took out the module and tested the wiring. It parks and low speed works just fine if I jumper the right wires. Took out the drawings and got to looking at the module. I could not resist had to take it apart. I guess the electical schooling and working with eletronics does pay off some times. Well I looked at the cheap A$$ board they made for the intermitant setup . It is just a RC curcuit not even high tech nothing to burn out. the only thing that can cause the problem is the relay on te board. I called Ford to get a price to a replacement $102 + tax. The components in this board cost about $1 wholesale. How is that for mark up.
