2005 Cobalt_Front power windows won't operate anymore

Power Windows Description and Operation
Power Windows System Components
The following components are used to control the power windows:
• Driver Door Module (DDM)
• Passenger Front Door Module (PDM)
• LH Rear Door Module (LRDM)
• RH Rear Door Module (RRDM)
• Driver Door Switch Assembly (DDSA)
• RH Front Power Window Switch
• LH Rear Power Window Switch
• RH Rear Power Window Switch
• LH Front Power Window Motor
• RH Front Power Window Motor
• LH Rear Power Window Motor
• RH Rear Power Window Motor
• Class 2 serial data circuit
• Power door serial data circuit
• PWR WDO 30 Amp Circuit Breaker
• DRVMDL Fuse (10 amp)
Driver Door Switch Assembly and Driver Door Module logic, Driver Door Module internal driver operation
• PASS MDL Fuse (10 amp)
Front Passenger Door Module logic and internal driver operation
• RRDR MDL Fuse (10 amp)
Left Rear Door Module and Right Rear Door Module logic and internal driver operation
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.

Did you hook up a scan tool an check for DTC'S in the driver door module ?

DTC B3142, B3147, B3152, or B3157

The switch that failed and generated this diagnostic trouble code (DTC) is wired to either the driver door switch assembly (DDSA) or the passenger door module (PDM). The DDSA or the PDM includes the switch state in the message it sends to the driver door module (DDM) via the power door serial data circuit. The DDM sends the switch message to the rear integration module (RIM), which is the master of all lock operations, as a class 2 message. The RIM checks all conditions and if all conditions are correct, sends its OK to the DDM. When the OK message is received, the DDM sends the required signal to all other door modules via the power door serial data message system.

its the driver control switch

the switch is bad or lose. can it be opened from both the driver side and the passenger side controller? One switch may be bad and not the other or if both switches are good than it is in the wiring to the power window or motor.

Check all your wires ,make none have rubbed and exposed the bare wire .vibrations might cause the wire to short out on metal

Window regulator is bad in the drivers door . Do you know what a regulator is ? The Trainer 24 Power Window Troubleshooting Do you know anything about automotive electrical testing ? How to read an use a wiring diagram ? Do you know there are two side to a electrical circuit ? B+ voltage an a ground side . Plus there is electronic control modules and class 2 serial data network involved . When you push the switch for a window othen then drivers window on the drivers door . a class 2 message is sent to the other doors modules . The correct module will then open it's window .
http://www.bbbind.com/free_tsb.html Check out free wiring diagram here .Enter vehicle info . year , make , model and engine size. Under system click on body & accessories , subsystem click power windows . Click search button , then click each link one at a time .

make sure your parking brake is off first then if you take a hammer and hit the side of the drum while you tug on opposite side and do this all around it pulling evenly it will come off. hope this helps.

Your Cobalt is not equiooed with a Power Steering Pump. It has electric power steering. See the description below.

Power Steering - System Description and Operation
The electric power steering (EPS) system reduces the amount of effort needed to steer the vehicle. The system uses the body control module (BCM), power steering control module (PSCM), torque sensor, discrete battery voltage supply circuit, EPS motor, serial data bus, and the instrument panel cluster (IPC) message center to perform the system functions. The PSCM, torque sensor, not the EPS motor are serviced separately from each other or from the steering column. Any EPS components diagnosed to be malfunctioning requires replacement of the steering column assembly, also known as the EPS assembly.

ABS could be acting up. Have chk' asap.

Hi. the windows no longer work from drivers switch or each switch on the doors? I would turn key on not starting vehicle with door open (drivers) push each switch one at a time while watching dome lamp if dome lamp dims the motor is stuck if no diming occurs start witha window switch.
