Power Windows - Service Information: Other RAM Pickup 3500

WINDOW MOTOR

Window motors use permanent type magnets. The B+ and ground applied at the motor terminal pins will cause the motor to rotate in one direction. Reversing current through the motor terminals will cause the motor to rotate in the opposite direction.

EXPRESS DOWN WINDOW FEATURE

This feature allows you to remotely lower both front door windows at the same time. To use this feature, press and release the UNLOCK button on the RKE transmitter and then immediately press and hold the UNLOCK button until the windows lower to the desired level or until they lower completely.

EXPRESS-UP/EXPRESS-DOWN POSSIBLE CONCERNS

Note. The battery must be fully charged or the vehicle running for proper calibration of the front door module.

Note. The following procedure must be performed anytime the power window system has been serviced in either front door or, there is a possible concern with a door module calibration.

1. Glass will not lower all the way down flush to the belt-line.
2. Glass will not raise fully; wind noise / water leak.
3. Glass will not raise automatically (expess-up) after lifting the switch to the second detent and releasing.
