How to check windshield wiper motor in 1992 Jeep Comanche?
I had this same problem First check the fuse. Second check the 4.8 amp circuit breaker at the bottom of the fuse panel (these are common to go out but you have to get them at the dealer and they run about $30.00)Third check the switch with the switch key on wiper switch on take your test light and pierce the coating on the wire if those three thing are good your should get power on your test light no juice the check those three again. Finally take the motor hook it up with jumper wires to the battery, be sure you know which wire is hot when you do this.
