windshield washer pump 91 f150 lariat xlt


Asked by Mar 01, 2014 at 06:22 PM about the 1991 Ford F-150 XLT Lariat SB

Question type: Maintenance & Repair

Windshield washer pump quit working.   So I replaced it with a new one.  I made sure the hose was clean and the the holes in my jet at my cowl was cleaned out.  But when i turn the key over, the pump doesn't even kick on?  There's no relay for it or fuse that I have been able to find.  Can anyone tell me what to trouble shoot next?  Maybe a broken wire?  I don't know whats left to check.  Thanks for any advice on this.

Try the switch that turns on the wipers and also the button, if you have one, that sets the washer fluid in motion. If the blades themselves do not work, you are not getting power to the motor. Use a volt meter with the wipers on to see if you are getting power to the motor.
