Power Window System Controls (RPO A31/AN3/DL3)
The power window system will operate anytime the Retained Accessory Power (RAP) system is active or when the ignition switch is in the ACCY or ON position.
The driver master control switches are integrated into the DDS. When a power window switch is activated in the up or down positions the DDS supplies power and ground to the window motor control circuits to drive the window motor in the required direction. Prior to activating a power window motor the DDS will supply the control circuit with a low current bias voltage in order to determine that a short to ground condition does not exist and during window motor operation the DDS continues to monitor the motor current to verify proper window motor operation.
The DDS controls the passenger window through a GMLAN message to the PDS. When a power window switch is activated in the up or down positions the PDS supplies power and ground to the window motor control circuits to drive the window motor in the required direction. Prior to activating a power window motor the PDS will supply the control circuit with a low current bias voltage in order to determine that a short to ground condition does not exist, and during window motor operation the PDS continues to monitor the motor current to verify proper window motor operation. (Scan tool support is available for this system)

A/c blower motor works if I pull power and plug back in until I cut engine off. Then I have to repeat process


Daryl, You may want to check the blower relay/ just switch with one of same type and try and if OK, problem could be the blower motor, wires/plug loose,damaged,burnt or a faulty blower motor resistor. Second link has some trouble shooting of a overheating wire problem, that is to be common in these trucks. Check the attached links,instruction and guides, Good luck

Why is it my 2008 chevy uplander rear wiper motor/blade moves some and stops. I let van set 5-10 minutes with key off. Turn on key. Wiper motor/blade moves a few degrees and then stops again. Why?


Can you move the wiper by hand ? Which does your vehicle have ?
WDA/Z88 The rear wiper is controlled based on an input from the rear wiper/washer portion of the multifunction switch. When closed, the wiper ON and wiper DELAY switches provide a unique voltage signal to the rear window wiper motor indicating the desired speed. Each switch has a unique resistor that drops the voltage to a specified value which is interpreted by the rear window wiper motor as ON or DELAY. The rear wiper motor receives B+ voltage from the I/P fuse block and accessory voltage from the body control module (BCM).
W49 The rear wiper is controlled based on an input from the rear wiper/washer switch. When closed, the wiper ON switch provides a voltage signal to the rear window wiper motor indicating rear wiper operation is requested. The rear wiper motor receives B+ voltage from the I/P fuse block and accessory voltage from the body control module (BCM).

Why won't my window work


Check for:
(1) Bound mechanism - try testing the motor before installing, see if you can move the window up and down by hand.
(2) Good ground. Make sure you have both 12V & ground at the motor.
(3) Bad replacement motor. Although unlikely, you could have gotten a bad part. Try bench testing with a 12V battery.

2007 mitsubishi eclipse driver seat stuck rearward, wont release


  • Search for one of the most common troubles in power seats: inspect the seat rails and the area under the seat with a flashlight and make sure there are no objects obstructing or preventing seat movement.

  • Inspect the fuse or circuit breaker if both front power seats fail to op

  • Turn on the ignition switch, but do not start the engine. Operate the power seat switch and listen for the motor running under the failed seat. If you do not hear any sound coming from the motor, lift the switch from the door panel or the side of the seat.
  • Check for incoming voltage at the switch using a test light. If there is no voltage, check the wiring between the switch and the fuse panel for an open or short.
  • Unplug the switch and test it for continuity using a multimeter. If there is no continuity, replace the switch.
  • Test the relay if your circuit has one between the switch and the failed motor. Operate the switch and make sure the relay is receiving voltage from the switch; also, test for outgoing voltage from the relay to the motor using a test light. Make sure the relay is properly grounded. Remove or move the seat to the side if possible for this test. If one of the voltages is not present, check that part of the wire for an open or short. If there is no outgoing voltage, test the relay for proper operation and replace it if necessary.
  • Check for incoming voltage at the failed motor or motors using a test light. If there is no incoming voltage, test the wire or wires for continuity between the motor and switch or relay, looking for an open or a short.
  • Unplug the failed motor and test it outside, connecting the motor to the battery using two jumper wires. If the motor still does not operate, replace it.
  • Inspect the drive assembly-transmission, gears and tracks-and make sure the mechanism is in good condition. Make repairs as necessary.

    No fan for the heater


    First check the fuse for the blower motor in the fuse panel if it is blown replace it and see if blower works.If still not working you will need to buy a test light from your local auto parts store and check for voltage at the blower motor red wire if the test light shows voltage you might have a bad blower motor. There's a trick to test the motor called the tap test start the car and turn the heater fan on high using a mid size screw driver tap on the blower motor and see if it comes on if it does you need a new motor.

    2000 dodge dakota sport blower motor won't work


    Hi my name is Allen!

    This is a very hard motor to get out!

    This will save you time, if you have a test light and jumper cables, hook the jumper cables to the battery, then hook your test light to the positive side of the jumper cable, turn the ignition key on and turn the blower motor on. Next at the blower motor connector touch the test light to the negative side of the connector if the test light, lights up you have a good ground. NEXT; move the test light to the negative side of the jumper cable and test the positive side of the connector if it lights, you have power coming to the motor, if you have both power and ground you need to replace the motor, if no light on one side you need to repair the one that doesn't light up.

    For further assistance contact me at FixYa!
