The passenger seat will recline back, but will not let back up

Hello, The little tick that the switch makes when pressed will be there with or without power going to the motor, and I would suggest testing that the switch is functioning properly. Removing the switch and jumping from the pin that raises the seat and the battery power pin will let you know if the switch is bad. If the seat goes up when you short passed the switch, then the switch should be replaced. I would have a hard time believing that the motor is faulty because working in one direction is the same for the motor as working in the other direction.
