Windshield Washer fluid

I have had my repair shop 'fix' this problem twice. The first time they removed the resivoir to clean the screen and blow out the hoses. Motor is fine. During another visit they again checked it out, cleaned lines, replaced with new fluid and was operational leaving the shop. So in both cases it works for a day or two then goes out again. The motor still seems ok, as I can hear it [audible sound] when activating to pump fluid (resivoir full). They can not seem to find anything else wrong with this system. This is not a dealership repair so there could possibly be something they dont know about. This would be a bigger problem if I had payed for those 'repairs' but since I have not it is not a big issue; I just want it fixed so it continues working beyond said day or two out of shop.

Anyone else have this problem? If so what is the cause, necessary repair and cost?

I am taking the vehicle in again very soon for repairs; a speed sensor [2nd time in 6 months; I hope] and would like any feedback about this problem.

Thanks in advance.

BTW: Great thread about the speed sensor/ABS control module, very informative and helped out a lot. Definetly let me know why my lights came and stay on. Thanks all.

Try replacing the lines. You may have a hole somewhere causing a slight vacuum leak that prevents the pump from drawing fluid as it cavitates on an air bubble.

Thanks for your input. They took the whole pump unit out to clean and blow the lines. Works good now. But I'm keeping my fingers crossed (the good part is I'm past the couple day mark.

I had the same problem, it's the splitter or "3 way line splitter" from the main fliud line to the lines to each spray nozzle. The factory one gets clogged, remove it and get a generic for a $1.49.
