I have a 91 s-10 rwd. I am unable to find the problem with the washer motor not running, replaced fuse, and motor. I there another fuse/relay I may need to change, or are we looking at replacing the switch entirely?
That's what it sounds like, or you can just wire around the stock switch and install a small push button on the dash somewhere to run the washers.
I'd juice the washer motor with 12 volts and see if that one isn't defective~these are a failure item because of the liquid environment....electrical/moisture would be a problem~
You can also try this; Sometimes the wiper motor can be frozen or stuck. Try to free it up! Use 'Silicone Lube' and spray connections where blades mount on hubs - Turn wipers on high - Grab wiper blades - Push in wiping direction. "Corrosion may be a factor" Let us know, OK?
