Re: rear wiper will not work
There are no relays in the back door that i know of, however it sounds like the gearbox in the wiper motor has broken. if there is power to the plug and a good earth, then its got to be the motor. just one thing to check.. make sure the wiper arm is tight on the spindle. I have seen them come loose and give the impression the motor isnt working, could also explain clicking noise.

The rear wiper motor assembly may be defective/seized. You can try turning on the rear wiper and moving the wiper arm with your hand to see if it will move even a little bit. If you can coax it to move, the wiper motor is bad and needs replacement. If it doesn't move, you will have to disassemble the rear hatch panels and test the motor directly for power and ground.
There is an electric motor that runs the wiper in the rear hatch. Remove the rear plastic panel and verify that the motor is getting 12 volts, using a multi-meter. If it is, then the motor needs replaced. If not then the wiring is likely bad between the switch on the dash/stalk and the rear wiper. The wiring may have broken where it goes into the rear hatch, also.
Check fuse panel ...if fuses for those rear devices are OK look at the wiring at the rear hatch. Possibly inside that door, or a ground condition that is not functioning or disconnected connector related to electrical devices in the rear hatch door. Good luck!
If you hear a clicking sound, then you know you have power. Check to see if the motor arm is moving any at the wiper arm.The small cap that covers the wiper arm to motor can be pulled apart, to see if the nut is loose or if the gear housing is stripped on the wiper arm, or if the motor drive is stripped. These are say to check and are cost effective for you.
first check fuses if all good remove back hatch panel find wiper motor remove plug . turn the ignition key to on position turn on rear wiper now test wiper plug for power if no power replace wiper motor
Check the wiper motor connection if its touching anything and loose it will automatically ground out and check at connection make sure you put some gel and then snap it in/ Please rate my response thank you very much
Sounds like a dead short to me. You will need to find a wiring diagram for this one. Without it, I'd start by unpluging the motor and the light one at a time. Another good place to check is at the rear hatch, where the wiring harness enters the hatch, this is a common area for broken/shorted wires.Check that and let me know, I'll help how I can.
