Power Window in 99 Grand Am came down and won't go up

There are a few possible reasons why the front and back passenger side windows on your 99 Durango aren't rolling down:

1. Faulty window regulator: The window regulator is the mechanism that moves the window up and down. Over time, the regulator can become worn or damaged, making it difficult or impossible to operate the window.
2. Electrical issue: It's possible that there's an issue with the electrical system that powers the passenger side windows. This could be caused by a blown fuse, a faulty switch, or a problem with the wiring.
3. Window motor failure: The window motor is responsible for moving the window up and down. If the motor is faulty, the window won't move.
4. Window switch problem: The window switch could also be the culprit. If the switch is damaged or not functioning properly, the window won't roll down.

To diagnose the issue, you can start by checking the fuses related to the power windows. If the fuses are intact, you can use a voltmeter to check if the switch is receiving power when it's pressed. If the switch is getting power, the problem could be with the window motor or regulator.
If you're not comfortable performing these diagnostic steps, it's best to take your Durango to a qualified mechanic or automotive electrician for further inspection and repair.

Did the switch work before replaced battery ? 2008 CTS ? Cadillac ? These switches are inputs to a control module , DDM - driver door module . a computer of sorts . A lot of thing's can go wrong with these systems , broken power or ground circuits inside the rubber boot from the body to the driver door . Communication problems between control modules etc... Plus the power windows don't use fuse's , has a circuit breaker for front windows - PWR/WNDW circuit breaker 25 amp located in the fuse box under the back seat , Fuse's are used for rear windows - two 15 amp fuse's LT/REAR an rear ,both are in the rear fuse box under back seat. These rear windows are controlled by the BCM - body control module .

The power windows system consists of the following components:
• Driver door module (DDM)--GMLAN device that receives and transmits messages and signals for window functionality. The DDM contains the driver door switch (DDS) which is integrated into the module. The DDS contains the driver, front passenger, RR and LR window and window lockout switches.
• Passenger front door module (PDM)--GMLAN device that receives and transmits messages and signals for window functionality. The PDM contains the front passenger door switch (PDS) which is integrated into the PDM. The PDS contains the front passenger window switch.
• Left rear power window switch--Provides switched voltage and ground window switch signals to the left rear window motor for left rear passenger window operation
• Right rear power window switch--Provides switched voltage and ground window switch signals to the right rear window motor for right passenger window operation
• Left front power window motor--Contains position sensors and a module that receives signals from the DDM and provides a status signal to the DDM
• Right front power window motor--Contains position sensors and a module that receives signals from the PDM and provides a status signal to the PDM
• Left rear power window motor--Contains position sensors and a module that receives signals from the left rear power window switch
• Right rear power window motor--Contains position sensors and a module that receives signals from the right rear power window switch
• DRIVER DR MOD fuse (15-amp)
• PDM fuse (15-amp)
• PWR WNDW Circuit Breaker (25-amp) -- front
• LT/REAR/WNDW fuse (15-amp) -- rear
• REAR/WNDW fuse (15-amp) -- rear


Power Window Operation
The driver and front passenger doors are equipped with power window motors that contains its own module. Each power window motor receives a hot at all times battery supply voltage and constant ground source. When the right front passenger window switch on the DDS is activated to the up or down position, the DDM will interpret the signal and send a GMLAN serial data message to the PDM. Upon receipt of the message, the PDM will send a signal to the front passenger window motor module on the GMLIN serial data circuit. The window motor module will then supply battery voltage and ground to the window motor to drive the window motor to the up or down position.
The DDM communicates via the GMLAN serial data circuit with the body control module (BCM) to control the rear window functions from the driver master window switch. The BCM is hard wired to each rear power window switch with circuits for window up, window down, and an enable circuit. The rear window switches contain internal logic that when supplied with voltage from the BCM over the enable circuit will driver the appropriate window in the direction commanded.
The rear power window switches are supplied with battery voltage from individual right and left WNDW fuses located in the rear fuse block. When a rear power window switch is activated to the DOWN position, voltage is applied to the motor down circuit and the motor up circuit serves as the path to ground. The window motor will drive in the downward direction until the switch is released or the window has fully opened. When the window switch is activated to the UP position, voltage is applied to the motor up circuit and the motor down circuit serves as the path to ground. Ground for the left rear power window switch is supplied at G200 and the right rear power window switch receives ground at G201.

The power locks work the same .

After replacing the driver door switch (DDS) or passenger door switch (PDS), perform the programing procedure.

If you don't know any of what i posted your best bet , have a qualified repair shop check it out .

Switches could be faulty try replacing them.

Window motors bad but if you do end up replacing it, first check for power at the plug going to the window motor when you use the switch.

replace the window regulator the cable prob. broke

How To Diagnose your Power Window Problem Is the Switch or motor bad

Have you checked the door switch?

If they sound like they are trying to do something it's not the lock out switch . But to be sure pulling out the switch an testing for B+ voltage to and from the switch . Plus pull the other door switches to see if they have B+ voltage and good grounds would be the thing to do.. If you don't know how to check automotive electrical circuits your best bet , take it to a qualified repair shop .
Passenger Power Window Operation
The passenger power window switches incorporate window up and down relays. The relay coil feed and supply sides are powered through the RAP fuse supply voltage circuit. The normally closed contacts of each relay is connected to ground. The load side of each of the relays are connected to either side of the power window motor through the power window up and down circuits. The up and down relay control circuits are connected to the normally closed contacts of the passenger window switch. These contacts are wired in series with the power window master switch, through the power window master switch up and down signal circuits and then to ground when the power window master is placed in the up or down position. This allows for the up and down operation of the passenger power window from the power window master switch. The center pole of the passenger power window switch is also connected to ground and will energize the relay when placed in the up or down position.

Driver Power Window Operation
The driver power window is unique from the passenger power windows in that it does not use window up and down relays. The driver power window is operated directly from the power window switch.
The normally closed contacts of the switch are connected to ground and the center pole is connected to the RAP fuse supply voltage circuit. By placing the left power window switch in the down position, voltage is applied to the power window motor left front down circuit and to the power window motor. The other side of the power window motor is connected to ground through the normally closed contacts of the left power window switch through the power window motor left front up circuit and drives the window down.
By placing the left power window switch in the up position the polarity of the motor is reversed and the motor drives the window up.

Has circuit breaker for B+ power
• PWR WDO CB 25A (fuse block) (System power for left and right windows 2-door vehicles. System power for LF and LR windows 4-door vehicles)
• PWR WDO CB 25A (IP wiring harness junction block) (System power for RF and RR windows 4-door vehicles)

Could be passenger door switch .

check the wires that run from the door to the body near the hinges. they always break inside that rubber boot.

Test the window switch for proper operation at both switches, if neither works then you will have to replace the power window motor.
