The other day my wipers suddenly came on while driving and wouldn't turn off until I pulled fuse out. I also noticed that the windshield fluid is not pumping. so is the problem the pump or wiper motor and how do I figure it out. I have close to 300K on this truck and love it. It has been the best truck.

They are both powered by the same fuse; Possible wiper motor, it is powered through the blue wire at the wiper motor connector from the wiper switch.
Even with the fuse in, the windshield is not pumping. So would that be the pump or motor? thank you
Either the pump, switch, or clogged tubing, clogged nozzles, or broken/loose water supply tubing. Could be a bad connection at the pump motor.
Will check it out. thanks
I have seen the connectors get dirty and not make a good connection causing the pump not to engage. Good luck and let me know.
