Wipers in my BMW E36 coupe 1994 work only on highest speed. What can be the cause?

Yesterday they stopped working properly. Now they work only when I start the engine and put them on highest speed! Can't be the motor obviously.

Been searching around and few other ppl had the same problem, but couldn't find solution or at least the cause.

Any BMW experts around here? Please help!Wipers in my BMW E36 coupe 1994 work only on highest speed. What can be the cause?Faulty wiper relayWipers in my BMW E36 coupe 1994 work only on highest speed. What can be the cause?
The wiper motor is not controlled by a regular relay. Battery power is supplied through fuses #3, 36, 37 %26amp; 44 (30 amps, 30, 10 %26amp; 15 respectively) to the wiper/washer control module, which gets signals from the wiper switch, and then the module runs the motor based on the switch setting.

I agree that the motor being bad is a very slim chance since it runs at high. So it is either a bad switch or a bad control module (which by the way is simply a glorified set of relays). The control module is behind the glove box, it is the first or the second one from the bottom at the middle area, beneath the zke/general body module which is a bigger sized module.

Proper diagnosis would be to check that the fuses are good and that the switch gives signals to the wiper module, that the module gives signals to the motor itself, and that the motor moves in both slow and fast modes.

But I would go for an easier check. Just look at the pins of the switch and if they are not burnt then replace the module.Wipers in my BMW E36 coupe 1994 work only on highest speed. What can be the cause?It's probably the switch itself on the column.



German switchgear from that era was kinda' cheesy anyway. It was an improvement over the E30, but not really what you'd expect from "The Ultimate Driving Machine".



I still find horribly underengineered switches on current BMWs all the time. Check out the cheesy POS brake switch on an X5 if you don't believe me.

Bad windshield wiper motor. Replace the motor, but I don't know how accessible the motor is in your specific vehicle, but I am sure it is an easy fix.Wipers in my BMW E36 coupe 1994 work only on highest speed.
