I have what I believe to be a Trico Windshield Washer pump model AWS-2. It came from a 55 Chevy and is not in operable condition, although all the pieces appear to be here. I would like to see if I can find a shop that rebuilds these, or if parts available, or even service instructions to be had before I jump into machining my own. I would be looking for the plastic lower check valve assembly, and a vacuum diaphragm?
Any help would be appreciated
Great news, I found a Trico windshield washing unit rebuilder in Maryland. The washer is in his hands now. I'll post the results when the jury comes in.
