2007 town and country
We picked up this 07 t&c with a burned up transmission, put in a used unit and all is well except a couple small problems. The driver power door does not operate, the latch clicks when you press the overhead button but it does nothing else. I first replaced the wiring, which is the most common issue, no change. i swapped the motor and control box side to side and the passenger door continues to operate but the driver door still acts the same. What do I check next?
