E46 Windshield Washer Pump DIY

Thanks so much for this DIY thread. Multiple posts lead to my executed job. The visual aids were great and the follow up replies added great added details and tricks. Never get rid of this DIY thread.

Thanks

Thanks guys for keeping this post up. I used it to fix my windshield washer. I had done the replacements but it still din't work. I was getting ready to try the cavitation method but found that the hose was kinked. I fixed the kinked hose and it worked perfectly!

This is indeed a great DIY post I replaced mine today and it only took about 10 minutes....Piece of cake! It just amazes me how much a stealership tries to charge people for doing something so simple.....

Thanks for this post...i just changed my pump and I feel liberated and not binded to the dealer prices.

Thanks Man!

I replaced the headlight washer pump on my 2003 325xi, and in the process I damaged the white nylon or plastic connector that attaches to the hose, that goes out to the nozzles, and fits to the pump. I just hate to have to go to the dealer for a replacement. Does anyone know where I can find the part number, and where besides the dealer, I can find one?

my filter was clogged so i cleaned everything out and now it shoots washer fluid straight over the car, any way to turn down the pump or change the angle?

I have not attempted this yet however based on the writeup I can see I am well capable (considering I was able to change my breaks etc).

My windshield sprayers stopped working, car was sitting i driveway for 3 months with occasional 2 times a week start and.drive around the block. It stopped spraying the fluid. So I check the reservoir, it isfull. Naturally next i check the fusebox (found reference on that litte fuse chart stating "windscreen washer system" no. 49,52,59 with 5amp 30amp 30amp respectively. I tested all three lil light turns out so I'm all good with fuses.

I would appreciate if you can help me narrow it down even more. I do not want to remove the pump if hoses are clogged. I have not tried the trick with "sprayers and needles" as in poking the spraying hole. I must admit a lot of fuzy stuff and debris fell on it over the months, but i would not think it would clog so easily considering the tiny size of the hole would it?


It seems that previous posters all had washer pump leaks. Does it always leak? And would a wusher pump cause the washer fluid tank to leak out? Because mine is full.

Lastly, if I should check the hose that runs from reservoir to the actual sprayers, or from the water pump to the actual sprayers, do I have to remove the tank to get to the house? How to check the clogged hose? You mention removing that part and trying to squirt. What should I do based on my info, I am a newb. I plan on doing the cheap pump trick but want to make sure it is not a hose.

Also, last resort if it is the pump how to do you properly wire the cables? Does it mean it does not just plug in? I have wired my speakers before in the door with black tape, but this is under the good and I want to seal it off properly not to cause future electrical problems. Any hints appreciation on that as we'll -id especially appreciate general writeup for connecting two wires with some kind of plastic cap, dunno never did it the right way and this time I want to do it. Other thant car runs good. 2003 325xi

When I had the problem, the fluid would very slowly leak out from the defective pump. And, again, I bought the pump from the BMW dealer - way over priced, but so simple and quick to replace.

Same set up on the X3. I got mine on Ebay $10.95 OEM shipping included.

I finally got around to doing this repair today. I bought the TAAP Corp pump from Autozone and the wires are as posted earlier in this thread = connect the blue/yellow one to the black wire and the blue/red to the brown. The pump from autozone contains to two wire taps to help make the connection. If you have never used them before, here's a link to a quick video on how to connect the wires with them:

I seem to be experiencing this problem. Wipers activate, but no washer fluid from either headlamp washers or the winshield washers. Do you I need to replace more than one pump???
