I have the power seat from a 2000 Monte Carlo in my truck. My problem is the passenger seat will not go down in the rear. The seat goes forward and back and the front goes up and down but the rear went up and will not go back down.
please help !
Thanks in advance

 

The green and yellow cables motor is powered by the blue plug. I believe the white wire is down, make sure it is powered when the switch is down - check the light blue for up. If only one powers, the switch is probably bad. If both power, the motor or cable drive is bad. I think the plugs will interchange, the black plug is front up/down.
