[QUOTE="Nic_dEntremont, post: 456322, member: 24390"] Here's some more info for you all about this (and maybe more) issue. I sent my Jeep to another dealership. This place was highly recommended over the other one I went to. The tech traced a short circuit to a connector near the passenger side headlight. Apparently there was that green corrosion connecting battery voltage to two CAN C bus connectors. CAN C does the powertrain modules. He cleaned the connector and bypassed the wiring harness by splicing the wires together. Below are some images and scans of the reports they made. I hope it helps someone.

Hopefully that's the end of electrical issues for now. I'm thinking of investing in some dielectric grease. [/QUOTE]
