my 88 turbo full time 4wd turbo wagon , the high speed of the wipers does not work , would it be in the switch on the steering wheel, ? or wiper motor or connection , if it is in the? switch how hard are they to change ? i have spare switches :wave:

If the intermittent wiper part works, I'd test the switch last. The high setting s right between the low/int settings, so the contacts are probably good. Check the motor--put the switch on high with the car running (wet the windshield first so it doesn't scratch) and nudge the wipers. Sometimes they're just frozen. And we all like simple fixes.

Need a test light to do this, or a multi-meter.

Sorry, I don't have color code of wires for this.

At the wiper motor connector, with key on wipers off; you should have battery power on one lead. This is the power feed to park the wipers.

Turn the wipers to low; you should have power at one of the other feeds.

Put the wipers on high; you should have power on the last of the wires.

This will rule out the switch and wiring, and point you to the motor as being bad.

I take it that they are working on the low setting?!? This would tend to rule out the ground as being suspect.

 

PS: I'll see about next week end, but no promise of being there.

PSS: Let you know on the other, give me a day or two.

yes the low speed works, and the intermittint works, will check all thanks,
