Before anyone dismisses this as a typical "you forgot to check this" thread" I'm hoping it's that easy, but I don't know what I'm missing.
So my washer pump quit working just as we started getting snow of course. No big deal, check the fuse all OK, wipers front and rear work. Couple of bolts and two nuts and the washer/ coolant reservoir is out. No clogged screen, so pull the pump. Insert 12V test light to positive socket of pump harness and ground negative to battery. Push the squirter button and on comes the light so button is working. Changed leads so light is on negative side to prove I have a good ground. Yep all OK.
Purchased and installed new pump. Worked once and then quit.Still won't work. Checked fuse again and now it's blown. Replaced fuse and still no pump. Found a splice in the harness of both wires so it could still be a grounding issue. Cut wires and retest./ Each time the button is pushed my light comes on, but no pump. Pulled pump and direct tested with 12V from batter. Pump works fine.
I'm starting to think at 53 my brain is failing. How can something this simple be so frustrating. Is there something I'm missing. I don't see a relay of any sort that could be dropping my voltage enough to prevent the pump from working. I ran out of time to get my meter in there to be sure that I'm getting 12V, but the test light is nice and bright. I just nutted the wires back together so I could test easier until I figure it out. I'm also thinking of splicing in another ground to see if there is a ground somewhere else that's bad.
