Most likely a broken pump, blocked tubing, or blocked output on your container. Be prepared to lose a lot of your fluid while doing the tests below, You may want to save it first (by suction tool or other manual pump).
#1 - Try pulling out headlight pump (by exerting weak vertical pull), and see if liquid drains out of the washer liquid container. This will ensure your container is not the issue, and that debris is not blocking the passage to the headlight pump.
#2 - Try disconnecting headlith pump output tubing. Fluid should free flow out immediately.
#3 - Try activating your pump, without output tubing attached to it. Fluid should spray out into your engine bay. If it doesnt, you need a new pump, and strainer (see OEM part numbers listed below.


Strainer for wash pump, part # 61678374382.

Bought mine off ebay for $14 in late 2010 (AutoLampsPlus), but they dont carry it anymore. Stills works after tow Candaind winters.
Found another store (Deutsche Parts) that sells one for $27 here. Unsure about quality ...
