Passenger window will go up but not down

The passenger window will not go down but it will go up, when i check for power i find that i have both power on both wires going to the motor when i push the switch for up and down. when i pulled the motor off the window can be pushed down easily. and the motor will only turn in one direction when i push the switch to go up but will not work when i push it to go down even when it shows power is going to that terminal.

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.

Why does the power window button blink on and off and the automatic feature doesn't work in the 2008 Toyota Sienna?


NOTE:
Anytime the batteryterminal has been disconnected, please initialize the driver's door power windowand front passenger's door power windowafter reconnecting the batteryterminal.

With ignition switchin the "ON" position, do the following:

1. Push down and hold the driver's door power windowswitch to completely open the window.
2. Pull and hold up the driver's door power windowswitch until the window closes.

Continue holding the switch for approximately one second until the switch changes from blinking to a constant illumination.
3. Check for proper operation of the "one-touch open and close" function by fully pushing the switch briefly to the "DOWN" and "UP" positions.

At this time the power window switchfor the passenger's door windowshould be blinking.
4. Push down and hold the passenger's door power windowswitch to completely open the window.
5. Pull and hold up the passenger's door power windowswitch until the window closes.
Continue holding the switch for approximately one second until the switch changes
from blinking to a constant illumination.
6. Check for proper operation of the "one-touch open and close" function by fully pushing the switch briefly to the "DOWN" and "UP" positions.

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.

If your vehicle has these other options an they work , you have power to the door . There is an electronic module inside the door ,called passenger door module ! where did you check for power at , the window switch ! These are computer controlled an you would only see a few volts when pushing the switch !

  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.

Passenger electric window will go down but not up


The master switch is the one located on the drivers side. If this switch has a malfunction it can rob power from the passenger side causing the problem you have. If the regulator/motor are in working order and you know the passenger switch is ok then that could be the problem. Another couple of possible problems could be a broken wire in the harness traveling from the car to the door (inside the rubber protective boot or a weak window motor (1990 is pretty old for a motor of that type.

Passenger window switch works but the drivers side switch does not


was regulator bad? did it work from drivers side switch before you did regulator repair?..if so passenger side switch wiring has issue and is not sending signal through it back to the drivers side master switches.. otherwise you need to pin test for power up power down on drivers side switch and repair that if issue going to the window on passenger side.. (possible pinched at door jam area common)

My passenger window won't go down


you should check the fuses first, then ensure power to the motor in the passenger side if no power check the switches for the power windows. Also it is common for window motors/ regulators to fail and have to be replaced. If the driver's one is running slowly remove door panel and lubricate the cables and tracks with some rust check or wd 40 etc, etc... and silicone lube on the guide tracks at either end of the window. hope this helps

Check the fuse panel first, after that check your fuse relays under the hood, if not then it might be a wiring problem.
