1996 Isuzu Trooper windshield wipers quit

My windshield wipers in 1996 Isuzu Trooper wouldn't work this morning. I replaced the fuse, but nothing happened. What should I check next?

 

Check the wiper-to-motor linkage, see if it came loose. Try to physically "assist" the wipers swipe across the windshield when the interior windshield wiper switch is on. If it slowly goes, if you feel the wiper motor pushing, double check to make sure it linkage is not loose, if so tighten it. If it isn't, locate your wiper motor (probably by your drivers side firewall) and clean the connectors, get a circuit tester and see if it's getting power. If it is not, follow the wires to a fuse or relay and clean/replace anything that may stop current from reaching the motor...If everything checks out fine, but the wiper motors will still not work, get the motor and the steering column wiper switch tested. Replace the faulty part.


Good Luck

 

good advice car boy, yes grab the wipers and try to move them. they should be very hard to move. if they just flop around, the linkage is popped off or broken(usually from turning them on when frozen to the windshield)


there's two power feeds to the motor, on the motor itself---blue is low speed input and white is high speed, both should have 12 volts with the appropriate switch position. check these voltages with the voltmeter's ground stuck into the black wire on the motor. this will verify the ground too. leave the connector plugged in, just stick your probes in from the backside of the connector


let us know what you find, and we'll go from there.

 

The wipers were very hard to move. It turns out that the wires had been chewed in-two, most probably by the pesky squirrel that I can't seem to get out of the upper part of the garage. So the motor wasn't getting any power. Thank you so much for the great advice!
