Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is***** you for the question. The most common cause of this is a wiring issue where the harness hinges into the hatch. The wiring in there tends to wear and short together. This needs to be pulled apart and inspected for broken wires. If the wiring is fine then it may be a module issue. I hope this helps. Please let me know if you need further assistance.
I will send you the wiring diagram shortly. If disconnecting the release button for the glass keeps it from opening then the button itself may have a short.
Sorry for the confusion. I would disconnect the switch on the door and see if it changes. If it stops then it is the switch. If not then it is more than likely the module. The module that controls this system is the body control module which is located under the left side of the dash.
Here you go
