Reocuring problem, have disconnected connection under seat with some success. Last time it worked for nearly 2 months then went out again. This is a very dangerous and irritating problem, I feel this should be a Chrysler recall to fix because if car seat is too far forward I cannot even drive my car safely.
Seats were working when the car went to the Chrysler dealership when the transmission failed. The service manager admitted the seats worked when he got in to help move the car inside the service area. Following transmission and transmission control module replacement (during which the dealer indicated he had problems with the new module "talking" with the car) the seats quit working. I believe he inadvertently caused the seat module problem but has refused to accept responsibility (states "it was just coincidence" the seat module failed while he was having issue with the transmission control computer working). I am trying to figure out if this is an owner replaceable module or if syncing with the vehicle computer is required.

Bought it used. Brought it home and within hrs the driver side seat was stuck fully reclined. After reading some posts I disconnected the plugs under the seat and got it to work long enough to adjust to the wifes height. But its not working again. Anyone know which wire to tap into in order to add a ground wire to the control module for the seat?

Took car in for service on ERG, Oxygen sensor, ABS sensor, 2 tire pressure sensors, throttle body cleaning and flushing for all systems. Unfortunately all these things happened in the past month. Never any other service to the PAC except PCM replacement, oil changes and wiper blades. After the service, the seats no longer worked, the cruise control no longer worked, and a new code p0420 appeared. The dealership fixed the cruise control by reattaching a vacuum hose disconnected during the throttle body cleaning and reset the code (if it reappears I will need a new catalytic converter). Anyway, they are refusing to pay to fix the seats but I will be calling their corporate office regarding TSB 08-039-05. After $2200 in repairs, it's hard to hear that they want another $350 to fix a seat system that had been working.
