Ok got it fixed. Thanks for the responses. Disconnecting the battery didn't do the trick. I had to remove the tank to get to the pump. I then cleaned the contacts and connector on the pump and no more warning light now. The contacts looked very clean, no corrosion at all. Maybe fiddling with the pump made the float get unstuck, who nows?
Here's a little write-up as to how to remove the washer fluid tank:
- remove front right wheel
- remove fender liner
- get all fluid out of the tank. It can hold about 6L (1.6 US gallon), you want it out of there. (WTF, 6L???)
- the filler neck is held by 2 little screws - remove those
- close to were the filler neck is attached to the tank, the is a 10mm hex holding the tank in place - remove it
- in the wheel well, there should be 2 tiewraps holding wire and a washer fluid line, loosen these up. Do not cut them, if OEM they can be retightened!
- the tank is fixed by one more 10mm nut inside the wheel well, you can't miss it
- now that the tank is loose, it should be easy to wiggle the filler neck off of it
- now the tank should slide right out of there
- the wires and lines are kept in place by plastic strips on the tank. Do not cut!! You can pop them loose on one end with a small screwdriver
- remove the connector from the pump and inspect the contacts - spray some contact cleaner on and in there
- gently remove the pump, it just slides into a rubber grommet
- make sure both the grommet and rubber o-ring where the filler neck goes are in good shape - if the rubber is hard, replace
- check if the warning light goes out, and/or functionality of the pump by submerging it in washer fluid. Make sure the connector stays dry, so not tóó deep.
- if all is well, you can put everything back together in reverse order. Do not forget to check for leaks before putting the fender liner back in!
- There is a ground near by, it is attached to the ABS-pump. It would be wise to clean it.
Quite an ordeal to get rid of a warning light.
And seriously? 6L of washer fluid?
