Got a question for you wiring gurus, so my 83 has the common problem of the interval wiper control module being bad, causing the wipers to be on all the time. The previous owner fixed this by jumping a wire off the fuse panel to a toggle switch which will turn the wipers on and off but I only have one speed. Id like to finally fix this problem and I was wondering if a wiper control module off a different 79-86 Ford would work as a replacement. I found a module off an 84 escort thats about $125 cheaper than one that came specifically out of a Mustang. The connectors and module are physically the same but the part number is different. Anyone have any idea if itll work? Ive already replaced the wiper switch on the column and the fuse with no change.
