How do I replace rear wiper motor?

Sounds like you might have a bad multifunction switch. You can test the outputs of the switch to confirm.

Here are some more common problems.

• Motor:

The wiper motor is commonly replaced and was often not the problem. Don't replace the motor yet. maybe it's not the motor. It could be a fuse or something at the wiper switch. The wiper motor has two windings, fast and slow. The wiper switch sends a ground signal to each motor winding. More often, there are problems with the relay, or at the wiper switch, or in the cable to the motor.

• Windshield Washer:

Don't be too quick to replace the washer pump. The problem is often just a clog in the sprayer heads. You can clean out the sprayer holes with a needle, some have two holes, so look closely. Hope this helps.

About rear wiper, if the fuse is OK, I suggest test the switch, the wires and voltage at/from motor; finally, test motor, possible go to bad.


Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Test for power at motor.


Test for power at motor. If you have power, then replace.wiper motor. trim should be held on with panel clips that can be removed with a special panel removal pliers






if

sounds like the turn signal switch is shorting out needs to be replaced.

you will need to remove the rear hatch panel,and take the nut and rear wiper off,then the motor bolts are easy to get out.

check for power at the wiper motor. If power at the wiper motor but no wiper action then replace the motor. if no power at the motor then use a jumper wire and put power to the motor. Does motor run? if so check for open circuit in the wire someplace.
