windshield washer removal tool S500 1994
 

I need to know how to remove the windshield washer spray unit from the drivers side. I cleared the holes with a needle, but I'm still not getting any spray. The entire assembly is enclosed. WIS say I need a 140-589-18-63-00 tool. Is there an exceptable substitute? Do you know of a source for this tool? ALso, where would the check valves for these lines be located? Thanks, Gary

Looked again
 

I looked at it again and I'll be darned if I can figure out how they come off. Any help???

I'm not familiar with your car, but on my '82 380SL and '79450SL the spray nozzle has two tabs that must be squeezed together to remove the nozzle. New nozzles aren't too expensive, I'd order a couple and have them on hand before attempting to remove the old ones. Performance Products has them listed, as I recall around $10 each. I broke mine when I removed them as the plastic was brittle.

Tool
 

On the 140 they are held in by a little plug that must be pulled out with a tool. I had pictures of it off WIS. I made one from an old screw driver and just kept cutting it down until it fit. You stick it in, turn it 90 degrees and pull gently. The little plug pops out, then you can remove the assembly.

It was full of scum. Blew out with canned air and then made sure with the air compressor. You can feel the air coming out of the nozzle holes with your tongue or want ever.

Test the washers before you go any further to make sure that the thing is getting water.

Reattach the heater circuits and the water hose and reinstall into the hood. Then just press the little plugs back into the housing. The side of the plug that has two ridges goes toward the front of the car.


Job done in 10 minutes once you have the right tool.
