I have a 2001 s10 2.2. The washer pump doesnt work. I replaced the pump and still dont work. Found a blank fuse spot that says w/w pump but you cant put a fuse in it. Has anyone else had this problem or any ideas how to fix it?

2.2 nust be a truch so only 1 pump (blazers have 2 - front and rear). The multifunction switch or blinker arm controls it so see if when you depress/turn to wash any voltage gets to the pump? Pump works when you run a 12v jumper to it?

I got it working. There is a break or short in the wire and when you move it around it works. I was able to tape it to another wire and keep it working

I have a problem with my washer pump. I have to turn it on a couple tim,es before it works. Not sure if it's the pump or switch.
