'91 Mazda with Crazy Wipers
courtesy of Bob, The Auto Answer Man
I have a 1991 Mazda Pretege. Around last fall my windshield wipers quit working. I brought the car in and my mechanic said the brushes were wet, he dried them and the wipers worked. This spring they quit working again, so I had a friend pick up a used motor at the salvage yard and install it. It worked fine. Now in the last two weeks, the wipers have quit working two times. If someone goes in and attaches the old motor that was previously in there and gets it to spark on the ground wire, the wipers will start working again ( using the "new" motor ). My mechanic bench tested the "new" motor and said it was fine. No one seems to know what to do. The switch appears to be in good working order. A friend thinks it might be a short in the electrical system. HELP!! Living in Minnesota, I really need my wipers, both in summer and winter.
These type of problems are hard to diagnose, but since you are getting 12 volts to the motor (since you need to "jump start" it) I do not think that there is a problem in the car, but in the motor. You might want to try spraying the brushes with "wire dry". This is the same stuff that you would spray on ignition wires or a distributor cap if it gets wet. Something else is WD-40. It is supposed to displace water. Another thing that you may want to think about is getting a newer unit from a retail outlet like Pep Boys (or its equivalent in your area).
