Default 2003 Grand Cherokee Laredo 4.7

Wasn't sure if I have the right place to post but my 03 Grand Cherokee all 4 power windows have stopped working. In addition, the temp readout in the above center console also stopped. Only the compus readout is operational. I understand this is common and checked the fuse 1st and then both door wire harness'. All is good to go. Don't know what to check next. I also noticed that the small flashing dash red light that is normally flashing when the car is locked is not flashing any longer also. The doors lock but no flashing light. I believe everything else is working ok. Any help or suggestions would be of great help. Thanks

Of all the options mentioned above I believe only the Tempature Data & VTSS where the doors lock but the small red interior indicator that indicates the car is locked is no longer flashing.

All the functions listed above are controlled by the body control module. I think at this point that you might need to take the door panel off and verify power to the door switch.

Thanks for the help. After checking the wiring and fuse all was good. Replaced the BCM with a used '04 (same part #) for $45 and all is back to normal. Thanks again.

As I mentioned earlier everything 'appears' to be working well but I just noticed that the 'red' flashing indicator on the dash when the doors are locked is not flashing. Any idea what the problem could be? Thanks again for any help.
