IF ALL THIS IS GOOD....YOU HAVE A BAD WINDOW REGULATOR OR RELAY...MOST LIKELY THE REGULATOR

2003 gmc envoy Windows fuse


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.

My power seats and only the power windows on right side quit working on my 2007 silverado classic lt1500 I replaced the circuit breakers already and it did not fix the problem


Does you truck have Memory Seats ? There are 2 options of power seat systems available in full size trucks. The first is 6 way driver and passenger power seats without memory. The second is an 8-way driver seat plus 4-way lumbar with memory, heat and optional cool function.
If you replaced the circuit breaker , did you check for B+ voltage at the switch ? If you have memory seats there is a control module that is in the mix.
For the power windows same thing here ,the BCM - body control module is involved .A factory Tech 2 scan tool is still the best tool to use ,checking data parameters .
The switch for the front passenger power window has 2 positions UP and DOWN, and it's position is a direct input into the PDS. Upon receiving a request for power window operation (switch activation), the PDS supplies voltage to the power window motor right front up or down circuit and grounds the opposite and the power window motor runs to drive the window UP or DOWN.
The front passenger power window can also be operated from the driver master control. The front passenger window switch on the driver master control has 2 positions UP and DOWN and it's position is a direct input into the DDS. Upon receiving a request for front passenger power window operation, the DDS transmits a GMLAN message indicating the changed switch position. When the PDS receives this message, the PDS supplies voltage to the power window motor right front up or down circuit and grounds the opposite and the power window motor runs to move the window UP or DOWN.
GMLAN - is a data bus communication network that vehicle modules talk together on.
Rear Passenger Power Window Operation (RPO A31/AN3/DL3)
The body control module (BCM) monitors the window UP/DOWN command from the DDS. When the rear window UP or DOWN command is received, the BCM sends a signal to the appropriate rear window switch. The rear window switches continuously monitor the up and down signal circuits, if no function is being commanded, the signal voltage is at approximately B+ voltage. If the UP or DOWN function is commanded, the BCM signal voltage drops approximately 5 volts and the appropriate rear window switch will then command the window in the UP or DOWN direction.
Your best bet would be to take your truck to a GM dealer !

You need a scan tool to diagnose these systems
Power Window Inoperative - Driver Door

1

Did you perform the Door Systems Diagnostic System Check?
Go to Step 2
Go to Diagnostic System Check - Door Systems

2

Operate the driver power window in the UP and DOWN directions.
Does the driver power window operate properly?
Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems
Go to Step 3

3

  1. Install a scan tool.
  2. Monitor the driver window status data parameter in the driver door inputs list.
Does the driver window status data parameter display an active state?
Go to Step 11
Go to Step 4

4

  1. Monitor the driver window status data parameter in the driver door module inputs list.
  2. Activate the driver power window switch in the up and down positions.
Does the driver window status data parameter change accordingly?
Go to Step 5
The data link connector (DLC) allows a scan tool to communicate with the class 2 serial data line. The serial data line is the means by which the microprocessor-controlled modules in the vehicle communicate with each other. Once the scan tool is connected to the class 2 serial data line through the DLC, the scan tool can be used to monitor each module for diagnostic purposes and to check for diagnostic trouble codes (DTCs). Class 2 serial data is transmitted on a single wire at an average of 10.4 kbps.

POWER WINDOWS NOT WORKING & POWER WINDOW/REGULATOR ISSUES


It can be issue with motor itself. If it's not going up, then how its working down. But still it feels like weak window motor or is issue with power window switch. Get the voltage tested at switch and motor. Also try another working window motor at not working window side.

My back automatic window went down and now won't come back up. No sound from motor. Checked fuses. Even took back seat apart but don't know what to do or what caused it. How can I get window to go...


it may need to be reset.

SECTION 501-11: Glass, Frames and Mechanisms 2001 Explorer Sport/Sport-Trac Workshop Manual
GENERAL PROCEDURES 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.

Every time i start my 98 buick regal ls my drivers window goes down


The only wiring schematic I could find for your car is for the 2000 Buick Regal, but I hope this helps,
since it gave me a reason why starting a car would cause the driver's power window to
go down, and no other window in the car - it has a special circuit component
(the "Express Down Module").

Its possible that the Express Down Module in the power window switch circuit has failed. This
module latches the "Express Down" switch in the "made" state until released by the "Express
Down Module." If the Express Down Module is latching the Express Down switch when it
shouldn't (at power-up) instead of when it should (at the window "down" limit), then the driver's
window would lower when the driver starts the car. The way to tell if this is the problem is to
note how fast the driver's windows goes down - if it goes down ALL THE WAY, then you know
that the "Express Down" circuit is involved (and therefore suspect the Express Down Module).
If the driver's window only lowers part of the way, then the Express Down circuit is exonerated.
See the various components of the driver's power window circuitry in the
2000 Buick Regal power window circuit schematic below.
