1994 325is windshield wiper blades won't turn on at all.

I got this car back in June and hadn't had to use the wiper blades until recently when it started to rain. I tried turning the blades on but they didn't move. Anyone have any ways to trouble shoot this? I've been looking but haven't found anything on it. Thanks for the help.

Check the fuses if you haven't already done that. If the fuses are good it could be either the switch on the steering column, the wiper control module, or the wiper motor.

Hey thanks for the reply I checked the fuses they all seemed good. So I was thinking about checking the voltage on the wiper motor to see if it was a relay. If it was the switch how would i go about checking that and would it be an easy fix? Thanks

Because the E36 has speed variable wipers, the wiper motor is controlled by the wiper control module. The wiper control module gets inputs from the wiper switch and the speed sensor so it can determine whether to trigger a wipe or not. If you check for voltage at the wiper motor be sure you move the wiper switch to the high speed position, otherwise you'll have no voltage at the motor because the car is stationary.

Thanks alot I'll keep that in mind when I get to the wiper motor. I just started trying to get to it. Also thanks for explaining about the wiper control module and the switch I wasn't aware. Learn something new about my car everyday.

So I went to hit the switch and i heard a clicking sound coming from the glove box area. So does this just mean its the wiper control module? Guess I'll be doing some more research today.

It could be the wiper control module, since it's clicking, but it's just as likely it the motor itself. Probably the brushes are worn out.

The module is expen$ive new. It would help to try a known good one in your car before you plop down the coin.
