The wiper motor isn't coming on, but shorting to the motor shows it works fine. I pulled the fuse for the wiper and the fuse for 4x4 right below it. I don't have a good wiring diagram.
--------- | 1 | 2 | Wiper fuse --------- | 3 | 4 | 4x4 fuse ---------
With the wiper switch on high, reading from battery negative to: 1=~.5v, 2=floating, 3=~12v, 4=~12mv. Reading from battery positive to: 1=~11.5v, 2=floating 3=~12mv, 4=~12v
I think that indicates to me that the ground side of the lower fuse is #4, while the ground side of the wiper fuse is #1? And I would think then that I have a break in the circuit somewhere between the battery and #2? Would the steering column switch account for the .5 v drop? And then what would that make the .4v from 1 to 4?
I really want to test by just shoving a jumper wire between 3 and 1, but I want a second opinion before I fry something.
