Question about 1999 Buick Regal

2 Answers

Left rear power window does not operate properly on my Buick Regal. Window was operated down and unable to close window. I removed panel and diconnected plug connector from window motor and with use of voltmeter was able to read 12 volts when switch was operated in down position, even though window will not open completely. When switch was operated in the closed or up position I had reverse indicator or minus sign on my voltmeter with no voltage shown on digital readout of meter.

You need to replace switch . You can get from dealer or ebay, Once they start acting up , you might as well replace, it
is quite simple . If you break the plastic
clips . look at them so that you understand how your new switch is installed . plug wire harness back and your done.

The leads should be reversed to get a reading on down position ,tap the window motor gently as you push the switch and see if that helps .
If so the motor is bad.........also on alot of vehicles the rear windows don,t go all the way down ,it,s a safety feature for kids or pets in the back seat.

Power Windows Operation
The vehicle is equipped with power windows controlled by the door modules. Each passenger door window can be operated, either from a switch built into the driver door switch assembly (DDSA), or from a switch mounted locally to its associated door. The driver door window can be operated only from the driver door window switch built into the DDSA.
When a window is operated from the DDSA, the DDSA interprets the window switch signal as a specific window switch request and sends the information to the driver door module (DDM) via the power door serial data circuit. The DDM examines the request and checks to see if it has received any class 2 serial data messages from any of the other vehicle modules (i.e. ignition switch position) prohibiting the movement of the window. If the window being operated is the driver door window, and if no prohibitive class 2 messages have been received, the DDM then applies voltage and ground to the driver door window motor to move the window glass as requested. If the window being operated is a passenger door window, and no prohibitive class 2 messages have been received, the DDM sends the request, via the power door serial data circuit, to the appropriate passenger door module. The passenger door module then applies voltage and ground to the passenger door window motor to move the window glass as requested.
When a passenger door window is operated from the power window switch mounted locally to its associated door, the passenger door module first checks to see if the DDM has received any prohibitive class 2 serial data messages. If there are no prohibitive messages, the passenger door module powers the associated passenger door window motor.
Both front door windows have the express down feature. This allows the front door windows to be fully opened by momentarily pulling the appropriate window switch lever to the second detente and then releasing.

Are all windows not working ? Two separate circuit breakers left & right . Both in rear fuse box . Fuse Block - Rear Beneath the left rear seat
Check for broken wires inside the rubber boot from body to doors.
Do you know about electronic control modules ?
The power window system consists of the following components:
?€¢
Driver door module (DDM)


?€¢
Passenger door module (PDM)


?€¢
Body control module (BCM)


?€¢
LR power window switch


?€¢
RR power window switch


?€¢
Window up and window down relays in each of the rear passenger window switches


?€¢
Window lockout switch


?€¢
Reversible power window motors in each of the doors (circuit breaker protected)


?€¢
LT DOOR CB 25A (System power for left rear window)


?€¢
RT DOOR CB 25A (System power for right rear window)


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 DDM contains 4 power window switches which are integral components. Closing any of the normally open, rocker type switches provides the DDM with a request for power window operation. The switches for the 2 front windows have 3 positions Up, Down and Express Down, while the switches for the rear windows have only 2 positions, Up and Down. Each of these switches and their positions is a direct input into the DDM. Upon receiving a request for power window operation, the DDM, transmits a class 2 message indicating the switch and it's changed position.
The PDM contains a single power window switch that is an integral component. Closing of this normally open, rocker switch provides the PDM with a request for the front passenger power window operation. The switch for the front passenger window has 2 positions Up and Down. Each of these switch positions is a direct input to the PDM.
The 2 rear passenger doors have there own switches. Each of the switches contain a power window up and down relay. A switch activation alone can control the up and down functions of the rear windows. However the BCM, upon receiving a class 2 message from the DDM, can control the set of relays which will activate the rear window motors.

There is no relay for power windows !
Power Window System Components
The power window system consists of the following components:
?€¢
Driver window switch


?€¢
Front Passenger window switch


?€¢
Left Rear window switch


?€¢
Right Rear window switch


?€¢
Window regulator motors in each of the doors


?€¢
PWR WINDOWS PWR SUNROOF Circuit Breaker 30A


When the ignition switch is in the RUN or ACCY position, or Retained Accessory Power (RAP) is enabled and the lockout switch is disengaged, battery positive voltage will be available at the passenger window switches. When an individual window switch is pressed in the down position, battery positive voltage is applied to the window regulator motor causing that window to open. When the individual window switch is pressed in the up position, voltage is applied to the window regulator motor in the opposite direction causing that window to close. The return path to ground is supplied through the inactive control circuit being normally grounded through the driver window switch.

How do I get my right rear window to go up?


Take the door panel off, Try hitting the motor to jar it as sometimes the motor jams as it has went down too far. Hook up the switch and jar the motor if that don't work you can remove motor and get window up and reinstall the motor. (No power, a wire is broken usually in the drivers door as the wires go thru door jams you will have to remove the rubber and pull on the wires individually and one will come into, the splice it back together, sometimes you have to add some wire. You must cut the bad out first. Good Luck!

Where is the rear window relay located on the 2002 Ford Explorer sport trac. Not the rear door windows but the very back window.


  • The power rear window is inoperative (Explorer Sport Trac only)
  • Circuitry.
  • Battery Junction Box (BJB) fuse 3 (30A).
  • Central Junction Box (CJB) fuse 20 (7.5A).
  • Power rear window control switch.
  • Rear window glass motor.

NOTE: The power rear window motor is not on the multiplex link. Any diagnosis and testing carried out on the power rear window will not involve the GEM module. NOTE: The reinitialization procedure must be carried out when repairs are performed on any part of the power rear window system including when the power rear window motor is removed from the window regulator drum housing, a new power rear motor is installed, a new power rear window regulator is installed, a new power rear window module is installed, and any operation in which grease or lubricants are applied to the power rear window system.

Rear Window Motor Initialization s1r~us~en~file=ani_caut.gif~gen~ref.gif CAUTION: Make sure that no obstructions are present in the power rear window system when carrying out this procedure.
NOTE: This procedure must be carried out when repairs are performed on any part of the power rear window system including when: the power rear window motor is removed from the window regulator drum housing, a new power rear motor is installed, a new power rear window regulator is installed, a new power rear window module is installed, and any operation in which grease or lubricants are applied to the power rear window system.
NOTE: All power rear window components (window glass module, window regulator, window motor, and glass runs) must be installed and torqued to specification before carrying out this procedure.
NOTE: Steps 1-6 must be completed within 30 seconds. The entire procedure must be completed within five minutes.
NOTE: Once the ignition key is turned to the ON position in Step 6, it must remain on until the entire procedure is completed.
NOTE: Steps 7 and 9 require that the power rear window control switch be held in the closed position until the power rear window motor stalls the window in the upper header seal. Step 8 requires that the window control switch be momentarily turned to the open position.
  1. Start with the ignition in the OFF position.
  1. Turn the ignition to the ON position.
  1. Press the power rear window control switch vent button six times.
  1. Turn the ignition to the OFF position.
  1. Press the power rear window control switch vent button six times.
  1. Turn the ignition to the ON position. The power rear window will move up-down-up-down approximately 20 mm (0.8 in). This movement indicates that the power rear window motor has entered initialized mode.
  1. Rotate and hold the power rear window control switch to the closed position until the window stalls in the upper header seal.
  1. Momentarily rotate the power rear window control switch to the open position and release. The power rear window will carry out a one-touch down operation until the window stalls at the bottom of the travel stop designed into the window regulator.
  1. Rotate and hold the power rear window control switch to the closed position until the window stalls into the upper header seal. Once this operation is complete, the window will move up-down-up-down approximately 20 mm (0.8 in). This movement indicates that the power rear window motor has been successfully initialized.
  1. Verify correct operation of the power rear window by moving the window to the fully open, vent, then fully closed positions

I have just replaced the window motor on the right front door of my 93 regal custom and the switch from the drivers panel will not operate it


Hi, if the window switch on the left door operates the window its one of two problems. 1. an open circuit from the drivers side switch. 2. the drivers side switch is bad. You can check the connector on the back of the Right window switch these are know to make poor connection. Good Luck.
