SW1 rear wiper circuit

[Alex Marcuzzi]

I have a 1993 SW1 and the rear wiper motor does not get any power. I am
using a Haynes manual to help me trace the wires going to the motor but for
some reason the circuit for the rear wiper motor is missing. I guess they
must have thought it was not important. If anyone has a factory manual could
you tell me where it gets its power? Any help would be appreciated.

Wow I look all over my manual in teh electrial diagrams and found no
instance on the rear wiper motor or switch.. Where is this switch located?

You could also turn the key forward and test the wires comming out of the
switch to see if the power is at the switch..

Perhaps the wiper motor is tied into another circuit. Perhaps the power
truck relase or trun light?

I had the same problem. The SW is the only S model with a rear wiper. My
guess is that Haynes used a diagram from a SL. It's a pain but you can trace
it without the diagram. You may want to remove the steering column cover at
look at the switch. Thereis two wires that run down the shaft and are
soldered to two points on the body of the switch assembly. Mine broke right
at the solder points. Some heat and a touch of solder and everything was
working again.
