Windows & air cond stopped working 9mos ago. How can I tell if the PCM should

Hello, These are all powered up through the total integrated power module and can be tested with a Chrysler scan tool. One thing you can try is a negative battery terminal disconnect reboot procedure. If that does not work you will have to take the Jeep to a repair shop for repair. If less than 36,000 miles, it is under warranty and will be repaired free of charge at any dealer. doing the battery disconnect may reset the module back to original factory default settings.
