Windshield Washer Fluid Not Working - Pump or Wiring?
I own a Nissan Sentra Classic 1993. When i go to use my window washer fluid by pulling on the handle, no fluid comes out. There is normally the washer pump sound when fluid is being sprayed but now there is no sound or liquid.
I've already checked the fuse, reservoir, and fluid nozzle holes for clogs. All is fine. My guess is the prob has to do with the wiring beneath the fluid reservoir and going into the pump, or the pump itself.
For the wiring, at the reservoir there is a set of wires going into the very bottom of the tank and another set of wires going into the pump. The wiring beneath the reservoir has one wire clipped. All other wires appear to be connecting fine. The clipped wire doesnt look copper or silver but more bluish-green.
How do i go about testing the pump and wiring to determine which is at fault so that i can get my windshield wiper fluid working again? I am not an electronic specialist but am willing to purpase any useful tools.
Thanks
Run a suitable gauge jumper wire from your battery's + post and touch it to the pump's hotwire. Your efforts should either get a whine from the pump, or no sound at all. If the former, then you've eliminated the pump as your trouble-check the wiring. Should you get no sound-chances are the pump is shot and needs replacement.
The bluish-green color on the clipped wire indicates it's oxidized and has been cut for quite awhile.
Good Luck!
