Why is my back windshield wiper not working?
One possible reason for your back windshield wiper not working could be a torn wiper blade. Over time and use, the plastic and rubber components of the wiper blade can become worn and torn, resulting in a loss of effectiveness. Another potential issue could be a problem with the motor or the controls. If there is a fault in the motor or control system, it could prevent the back windshield wiper from functioning properly.

How do I troubleshoot and fix a non-functional rear windshield wiper on my Jeep Wrangler?
To troubleshoot and fix a non-functional rear windshield wiper on a Jeep Wrangler, start by checking the wiper motor fuse. Consult the owner’s manual to locate the fuse box and find the specific fuse for the rear wiper. If the fuse is blown, replace it with a new one of the same rating.
If the fuse is not the issue, the next step is to inspect the wiper switch. Use a multimeter to test if there is power going into and coming out of the switch when it is turned on. If there is no power, the switch may need to be replaced.
Another possible cause could be a faulty wiper motor. Disconnect the wiper motor and use the multimeter to check if it is receiving power. If there is power, but the motor is not functioning, it may need to be replaced.
If all the above steps fail to resolve the issue, it may be best to consult a professional mechanic or take the vehicle to a Jeep dealership for further diagnosis and repair.
