The rear verticle motor is jammed in the down position and I have tried everything mentioned in tsb 07-08-50-017A and am having no luck getting it unstuck. Anyone run into this before?

Looking at the TSB it doesn't mention to check if the motor or switch is getting power. It may be something to consider and check the switch, motor, connection and harness are in good condition and working with a test meter.

This happened on our PAU. Although the motors were getting power, the screw rod had come partially out of the threaded bushing, and jammed when we tried to return the seat forward. Our solution was to remove the seat, and disassemble the power mechanism, then, reassembling with the screw rod partially threaded into the threaded bushing. It was a pain, but so is having the seat stuck in one position. We never run the seat to its fully travel, forward, or backward, now.

The rear verticle motor is trying to move so I know for sure it is getting power to move both directions.

If it is getting power then it may be as suggested by Ultra Ego that the seat may need to be removed to correct the problem. There are some other post on this same problem TSB in this forum and Cadillac but no updated solution other than the TSB seemed to work.
