I have a 1997 LC with 215k miles on it. The front washers have never worked since I have had it for 4 years. I replaced the diverted and blew out all the lines. Rear works but front does not. I think it’s the switch in the stalk because when I removed the rear hose from the diverted then it sprayed fluid in the front when I turned the switch to the rear. Button on the end of the stalk doesn’t move and wanted to see if there was a fix without replacing the whole stalk.
