Chrysler Repair Questions? Ask a Mechanic for Answers ASAP
Do you have a scantool to see what codes are setting in the PSDM?
Have you checked the wiring harness at the bottom of the door for any breaks in the wire?
If your only having issues with your power liftgate then the very first step would be to check the codes in the PLGM which is the Power Liftgate Module. If you can borrow a scantool and not a code reader, then post the codes here so I can direct you to a repair.. I have attached the diagnostics..
