Headlight washer.

I am trying to get my headlight washer to work. Seems that there isn't power to the washer motor. When I check it with a volt meter, doesn't show volts when activated. The window washer shows 12 V when activated. I checked the fuses in the glove box., none were blown. When I powered the motor direct to a 12 V source, the motor turned, but it didn't pump washer fluid. So I guess I have 2 problems. The water pump part of the motor isn't working, and I am not getting power to the motor.

The headlights have to be on before the washers will work and they don't come on every time you pull the stalk. Get the new pump first and go from there.

Wow,,, thanks. That answers a lot of questions. I tested when the motor turns on. It runs the first time after you start the car, and not the next 6 times. Even though the washer motor is running, it still doesn't pump fluid. Like you said,,,, get a new motor/pump. Thx

Yah its the motor. Had the same issue a couple of years ago.

That's the way the headlight washers work only every 6th time do they spray..

Don't go to the dealer and pay $$$ for the motor.. You can get the exact same motor for like $10 from ebay because it fits previous gen BMWs and its much cheaper than if you were to buy the actual E46 branded/ part number # one..

I think i crossed referenced the numbers and getting the old motor # was much cheaper and fits like a glove in there

+1 on the EBay motors (used two of them on two different cars and they work fine). I think the BMW little plastic impeller sucks. It blows apart which unfortunately sends little bits of white plastic down the tubes to clog up your headlight washers and or make them leak all the fluid out of the tank. The little filter screen is before the pump so broken plastic can still get through when it breaks.
I tested the new ones by applying 12 V directly to the motorwhile installed instead of fulfilling all the requirements for the car to do it. Just a lot easier!
BMW could have done this so much better...
