Where is the wiper motor located on a 1989 jeep wrang ler
Its the black.......round motor that is at the back wall of your engine bay, could be on the drivers side,
A 1989 Jeep Wrangler needs 6 quarts of oil for an oil change.
Remove wiper arm caps, nuts & arms. Remove cowl louver cover. Disconnect wiper motor electrical connector. Remove 6 bolts and remove wiper linkage assembly. Disconnect wiper link from wiper motor. Remove 4 screws and wiper motor from firewall.
You need to get the windshield folded down. This means remove the top, then the front sport bar members. On each side is a bracket that holds the windshield upright. Remove screws to allow windshield to be folded down (gently) on the hood. The wiper motor is in the top of the cowl & should easily be visible. It might not be easily accessible, but it will be visible.
Possibly bad wiper motor, bad park switch, or bad wiper switch. Electrical short also possible.
There is a relay under the steering column inside the vehicle.
Check your fuse block or circuit breaker first, then turn wiper switch on and check for power at wiper motor, if the fuse/breaker is ok and you have power to motor, motor may be seized. listen for humming from motor, if none of above follow tech manual for testing wiper switch,or short to ground
Looking in my 1989 Chevy Celebrity manual I find a park relay inside the wiper motor but no reference to an external wiper relay. There is a fuse on the fuse block.
My '88 GMC did that Change the wiper/turn signal arm These trucks have a habit of getting water inside the electrical board of the wiper motor. I used to have to get out and hit mine to make it work the part is easily replaced ask your dealer and they should know exactly what part you need
On the right hand side of interior bulkhead under glove box.
Small black box mounted under dash by drivers left knee. Connected to wiper switch on one end and goes to wiper motor at the other.
