Windshield washer hasn’t been working so I pulled it out last week. The bracket was really rusty and in general it looked rough.
After seeing poor reviews for the $20 URO version not wanting to buy a Porsche version for $120 just yet I figured I would take a shot at it. Gears were jammed up with some kinda grit but the motor ran fine by itself.
Scrubbed the plastic bits with an SOS pad but the washer fluid seemed to have stained somewhat. Polished the brass bits inside. Sandblasted and painted the steel parts and sealed it all back up with a thin layer of RTV along with the original rubber gasket.
I didn’t have the time to pull off the washer fluid bottle but I did flush it out pretty thoroughly until no more bits of gunk came out. To do that I put the tube that would normally connect to the pump in a pan and then shot compressed air into the filler tube under the gas door. That worked really well and I filled it with hot water a few times and blew the water through until it was empty.
Only piece of advice if anyone else tries this is to not tighten the screws too much or it will bind up the pump. The most difficult part by far is getting the little rubber mounting things back in place on the bracket during reinstall today.
End result I now can wash my windshield, the color on the bracket isn’t original but I was glad to be able to reuse the original pump.
