How do i remove the back door panel to get to the rear wiper motor?

Most Chryslers from this year band require removal of the rear door's liner to access the motor. The motor is held on by two or three compression nuts with bolts that pass through the motor housing/frame. NAPA has new ones or you can use simple nuts and use both metal and rubber bushings to prevent possible rattling noise after mounting a new motor. A car or your year it is best to go to a recycle yard and get the whole assembly for cheap so you don't need to disconnect the motor from the wiper arm linkages. It's not difficult. The wiper must be removed from the back of the car and the large screw underneath the rubber gasket removed as well. The rest of the removal/install process is done from inside the rear door, once the rear door panel is removed.

Hello,

1. Disconnect the cable running to the negative terminal on the car's battery. To do this, loosen the nut on the cable clamp until the clamp is loose enough for you to slide the cable clamp off the negative battery terminal.
2. Pull the wiper arm away from the rear windshield until the wiper arm locks into a vertical or semi-vertical position or is perpendicular to the rear windshield.
3. Remove the nut holding the wiper arm assembly to the rear wiper motor.
4. Pull the wiper arm off the wiper motor assembly.
5. Unplug the rear wiper motor plug/harness.
6. Remove the screws holding the rear wiper motor to the inside of the vehicle at the base of the rear window.
7. Pull the rear wiper motor off.
8. Install the new wiper motor and put the wiper motor and arm assembly back on the vehicle by reversing the completed steps.

Check for power to your rear wiper motor. To do this you will have to remove the rear door trim. Once the door trim is removed check for power at your connector plug on the rear wiper motor with switch on. If there is power there than replace motor if not then start by checking fuses (which is a good idea to do before removing door panel because it's the easiest thing to check), connectors and wiring for damage and open circuit( cuts or broken pins in connectors or open/broken wiring)

You are probably correct in thinking its the wiper motor. You can do this but you will need to remove all the interior trim from the rear hatch first. Get a trim clip removal tool at a parts store...it will work much better than just a flat blade screwdriver. You'll have to remove the trim panels starting in order from the top of the door, then the left rear window side trim, then right rear window side trim, then the grab handle, and finally the main rear hatch trim panel. Once inside, removing and replacing the rear wiper motor is easy. You'll start by lifting the cover on the wiper arm retention nut. Remove this nut to get the wiper arm off, then remove the nut under neath which is the motor shaft mounting nut. Now, back inside to remove the other 3 motor mounting bolts. Don't forget to disconnect the connector for the motor wires. Reverse steps to replace.

good luck.

the plastic panel pops off , if you had a trim removal tool it would be nice but it can be improvised , they are just tension clips , get some kind of lever behind the panel and give it a pop , once the plastic panel is off its pretty much self explanatory from there , a connector and couple small bolts , now the outside has nut under the w/w blade , a piece of the arm cover pops up to access the nut , remove w/w arm , then a grommet and under the grommet is a bigger nut that helps hold the motor onto the door/hatch , when reinstalling before you put the w/w arm back on run the wiper and make sure it shuts off and in the park position . should be a piece of cake .

does the door lock from the passenger side with the key ? chances are if it is remote locking the door lock motor is probably u/s,remove the rear panel and check wiring at the motor for the wiper if you have power at the motor then your wiper motor is u/s too
