I have a 01 s600, washer fluid warning light comes on saying it is low, i fill it up, dont see any leaks, but with in a few days the light comes back on and it is almost empty. I removed the reservoir, it has fluid about 1/2 inch above the grommet/pump, and can not find any leaks. Couldnt see any leaks along the tubing, my eye sight isnt the best. I also have headlight washers, which dont work. Where should I start? New washer pump and grommets? Or is it something to do with my headlight washers? Any help would be appreciated.
