2005 Chevrolet Tahoe Power Windows and Power Locks not working.


The power windows an power locks are controlled by a module , DDM - driver door module . As far as the locks locking when you put the vehicle into reverse an unlocking when you put the vehicle into park , that's how there are suppose to work , automatic lock an unlock feature . When you put the vehicle into any gear from park the locks should lock . Did she hit window lockout function ?

The power door lock system consists of the following components:
• The driver door module (DDM)
• The passenger door module (PDM)
• The body control module (BCM)
• The driver information center (DIC)
• The rear door lock switch
• The door lock relay
• The door unlock relay
• The liftgate lock relay--utility vehicles with liftgate only
• The reversible door lock actuators in each of the doors and liftgate
• LOCKS 20A fuse (rear lock/unlock relay supply voltage)
• ECC 10A fuse (liftgate lock relay supply voltage .

Programmable Automatic Door Locks
The automatic door lock feature can be programmed to control the door lock system. The automatic door lock feature is factory programmed to have all doors lock and unlock. For detailed instructions on programming the automatic door locks, refer to Vehicle Personalization in Personalization.
When the automatic door lock feature is programmed to control the door lock system, the driver door module (DDM), passenger door module (PDM) and body control module (BCM) will lock the vehicle doors if the following inputs are true:
• Ignition 1 input is active.
• All door jamb switch inputs are inactive.
• Cargo door or liftgate/liftglass ajar inputs are inactive.
• Transmission is shifted out of park.
This automatic door lock function will only occur once per ignition cycle unless, a door jamb switch input changes state to active and back to inactive. Then the DDM, PDM and BCM will lock all doors again.
Once the automatic door lock feature has locked the doors, the BCM will then unlock all the doors when the transmission is shifted into park.
Driver, Passenger and Cargo Door Lock System Operation
The front power door lock switches are integral components of the driver door module (DDM) and passenger door module (PDM). The switches are two position normally open rocker switches. When placed in either the lock or unlock positions, the switches provide a direct input to the DDM or PDM. The DDM or PDM monitors these inputs and sends a Class 2 message indicating a change in the switch's respective position. Modules which activate the power door lock motors receive the Class 2 message and activate the motor in the appropriate direction to lock or unlock the vehicle's doors and liftgate. The rear door lock switch provides a lock and unlock signal to the body control module (BCM). The BCM upon receipt of a lock or unlock signal will control the rear door lock relays and also send a Class 2 message to the DDM and PDM to perform the appropriate function.
The modules which activate the power lock motors are:
• The DDM (driver door lock actuator).
• The PDM (passenger front door lock actuator).
• The BCM (both rear door lock actuators and cargo door/liftgate).
The DDM and PDM are directly connected to the respective door lock actuator through the door lock motor lock and unlock circuits. Once a door lock or unlock request has been received, the module will supply battery voltage to one side of the actuator and ground the other causing the doors to lock or unlock.
The rear passenger and cargo doors differ slightly in that they use lock and unlock relays. The relays supply and coil sides receive a constant voltage through the battery voltage supply circuit. The normally closed contacts are connected to ground and the control side is connected to the BCM. Once a door lock or unlock request has been received by the BCM, the BCM will ground the control side of the appropriate relay. This energizes the relay and allows voltage to be applied to either the door lock motor lock or unlock circuits. since the other side of the door lock actuator is connected to the normally closed contacts of the opposing relay to ground, the doors lock or unlock.

Power window switchs on 1996 gmc jimmy


Inspect or replace the window lock and unlock switch on the drivers door power window switch. There is a lock and unlock switch that will disable the switches to the other power window in the Jimmy. Check to make sure that switch is in the unlock position to have the other power window switch to work.
Thank you for suing fixya and good luck.

Camry 1996 automatic power lock doen't work, but windows work.


if you can here relays when unlocking/locking check for power at door lock actuators inside doors, if you have power on lock/unlock and good earth from connector actuators are faulty.
if no power on test light when operating check output from central door lock module while operating, none coming out of module then it might need replacing.
check 30Amp power fuse for main relay under bonnet (which goes to pin 8 white/blue on module)and 10Amp gauge fuse in cab(pin 1 blue/red on module),pin 15 is also power when relay is on(red/blue) with test light, and module/ actuators.
check outputs from module pin 3 & 4
blue/red
blue/black
that go to door locks

2000 explorer power window problems


There is a switch on some cars to lock out the windows to keep your kids from getting caught in them. This switch is a different shape than the others and is on the door or center console.
If you have a keyless entry system with numbers to push to unlock your car, sometimes the door switch forgets the numbers and needs to be reset. If you have a fancier car, the locks may have automatically locked as the car moved and once the door switch forgot the code it may have interferred with normal operation.

Rear side windows


This may be just a case of inadvertently hitting the window lock out n th driver door window switch by mistake. Check that first. Here's some background on window operation

Principles of Operation
The driver power window regulator motor is controlled directly by the master window/door lock/unlock switch (and its integrated "auto down" module). Power is supplied to the power window relay and the master window/door lock/unlock switch, and the passenger power window switch when the SEC/timer module grounds the coil side of the power window relay. The SEC/timer module will ground this relay when the ignition is in the ON position and will remain energized for approximately 15 minutes or until the driver or passenger door is opened.
The driver power window regulator motor is a reversible motor that is operated by applying power and ground to the motor leads to lower the window, and then reversing polarity on those leads to raise the window.
The passenger power window regulator motor is controlled directly by the passenger power window switch and can also be controlled by the master window/door lock/unlock switch. Power is supplied to the power window relay and the master window/door lock/unlock switch, and the passenger power window switch when the SEC/timer module grounds the coil side of the power window relay. The SEC/timer module will ground this relay when the ignition is in the ON position and will remain energized for approximately 15 minutes or until the driver or passenger door is opened.
The passenger power window regulator motor is a reversible motor, which is operated by applying power and ground to the motor leads to lower the window, and then reversing polarity on those leads to raise the window.
The power rear quarter glass is also directly controlled by the master window/door lock/unlock switch. The power rear quarter glass power latches also utilize reversible motors. The power rear quarter glass power latches are operated by applying power and ground to the motor leads to open the window, and then reversing polarity on those same leads to close the window.
