Windows and mirrors inop, fuses OK, no fault codes

Mirrors are separate from the other things.

Driver and Passenger Outside Mirror Operation
In order to control outside rear view mirror adjustments, two switches are contained within the driver door switch assembly (DDSA). The DDSA contains a built in mirror select switch and a built in mirror position switch. The DDSA reports the switch activity to the driver door module (DDM).
The mirror select switch is used to select which mirror, left or right, is to be moved.
The mirror position switch is used to move the mirror that has been selected to the desired position. When the mirror position switch is activated in a Up, Down, Left, or Right direction, the DDSA recognizes the input and sends this data on to the DDM via the power door serial data circuit. Depending on which mirror has been selected for adjustment, the DDM either moves the driver door mirror to the requested position, or sends a power door serial data message to the passenger door module (PDM) indicating that the passenger door mirror needs to be moved. The PDM then moves the passenger door mirror to the requested position.
Each mirror has two reversible motors for position adjustment. The door modules control the reversible motors by supplying Battery Positive Voltage (B+) and ground to these motors.

Outside Mirror System Components
The power outside mirror system consists of the following components:
• Driver door switch assembly (DDSA)
• Driver door module (DDM)
• Passenger door module (PDM)
• Driver outside mirror
• Passenger outside mirror
• Power door serial data circuit
• DRV MDL 10 A fuse (door module logic and internal driver operation)
• PASS MDL 10 A fuse (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 power window can be operated, either from a switch built into the driver door switch assembly (DDSA), or from a switch mounted locally on its associated door. The driver door power window can only be operated from the driver door window switch built into the driver door switch assembly (DDSA).
When the driver door module (DDM) receives a window switch request from the DDSA, the DDM checks the Class 2 serial data to see if the status information is correct (i.e. ignition switch position) to permit window operation to occur. If the status information is correct, the DDM, either supplies power and ground to its associated window motor, or, if the request is for one of the passenger windows, sends a command via the power door serial data circuit to the passenger door module (PDM, LRDM, or RRDM) controlling the window. The passenger door module (PDM, LRDM, or RRDM) controlling the window then supplies power and ground to its associated window motor to move the window as requested.
When one of the local window switches mounted on one of the passenger doors is operated, the associated door module examines the request and checks to see if there are any messages from the DDM prohibiting the movement. If conditions are correct, and no prohibitive messages have been received from the DDM, the associated door module then supplies power and ground to its associated window motor to move the window as requested.

The thing to do first would be to hook up a factory or some other type professional scan tool an check for DTC'S - diagnostic trouble codes.

DTC B3377, B3382, B3387, B3392, B3397, B3452, B3457, B3462, B3467, B3472, B3477, B3482, B3517, or B3522

Circuit Description
The switch that failed and generated this diagnostic trouble code (DTC) is part of the driver door switch assembly (DDSA). The DDSA contains a microprocessor which takes the signal generated by this switch and assigns a digital message to it. The DDSA then sends this message over a power door serial data circuit to the driver door module (DDM).

Same thing for locks.

The DDM must be powered and must not have DTCs B1327-Battery Low Voltage or B1328-Battery High Voltage set for this DTC to set.

Your best bet might be to find a good auto electrician.

Look at the end of the dash and between the drivers side door for a second fuse panel. I think everything you mention works on one data bus. You can remove the button pad on the drivers door. Since it gets used all th3 time i# might have gone bad messing up the works.

• All power windows are inoperative

• Fuse(s).

I could see one window not working from a broken wire inside the door flex , but not both back windows . Back windows are controlled by LF door module . Both back windows have different grounds - LR G200 an RR G201 . Also both rear window switches have different power supply's .RR switch fuse # 18 30 amp . LR is fuse b# 9 40 amp . Both window motors or switche's going out at same time ???? wouldn't think so .

  Inspection and Verification
  
  1. Verify the customer's concern by operating the power windows/heated back window to duplicate the condition.
  1. Inspect to determine if one of the following mechanical or electrical concerns apply:
     
     
     VISUAL INSPECTION CHART Mechanical Electrical
     • Front door power window regulator damaged.
     • Front window run damaged.
     • Front door window glass out of window run.

     • Scratched grid.
  1. If inspection reveals an obvious concern that is readily serviced, correct the concern before continuing with Inspection and Verification.
  1. If the concern remains after inspection, connect the Rotunda New Generation Star (NGS) Tester 007-00500 or equivalent to the data link connector (DLC) located beneath the instrument panel to perform DATA LINK DIAGNOSTICS test. If the NGS responds with NO RESPONSE/NOT EQUIPPED for the driver door module, go to Pinpoint Test A . If the NGS responds with NO RESPONSE/NOT EQUIPPED for the lighting control module, go to Pinpoint Test B . If the DATA LINK DIAGNOSTICS test is passed for the drivers door module and lighting control module, retrieve continuous DTCs and execute Self Test Diagnostics for the driver door module and lighting control module to retrieve current DTCs.
  1. If self test is passed and no DTCs are retrieved, go to the Symptom Chart to continue diagnostics.
  1. If DTCs are retrieved, go to the Driver Door Module (DDM) Diagnostic Trouble Code (DTC) Index or Lighting Control Module (LCM) Diagnostic Trouble Code (DTC) Index to continue diagnostics.
  1. If the driver door module cannot be accessed by the NGS, GO to Pinpoint Test A . If the lighting control module cannot be accessed by the NGS, go to Pinpoint Test B .

Vehicles equipped with remote keyless entry (RKE) have an illuminated entry feature, which enables the instrument cluster module (ICM) to illuminate the interior lamps (and if equipped, the puddle lamps in the exterior mirrors) when an unlock signal is received from the vehicle security module through the UBP network, or when any of the doors are opened. The ICM controls the interior lamps illuminated entry feature by activating the battery saver relay.

You'll need more then wiring diagrams ! A good scan tool for starters .
Youl

The thing to do first is have the vehicle hooked up to a professional grade scan tool an have it checked for DTC'S in the driver door module , an to see if the scan tool will talk with the module !
Then if no codes are present check for battery power an good grounds at the module ! You have to take the door panel off the door to get at the module . I have one of these modules out in my tool box , I got it at the auto salvage yard . $10.00
In order to control window operations, as well as other door functions, door modules must be powered up. Battery voltage is supplied by the rear fuse block, through separate circuits, to each door module. Each door module is separately grounded through a ground stake. Additionally, the door modules use these power and ground supplies to provide voltage and ground to their associated window switch, and to provide voltage and ground for door lock operations. The front door modules also use these power and ground supplies to power the window express up sensors, and for outside rearview mirror operation .

How to test computer controlled door locks

Instrument cluster problem maybe . Without testing we'd only be guessing . Have seen this a lot at the dealer . The best thing would be to hook up a factory scan tool an check for DTC'S - diagnostic trouble codes first. The electronic's on these vehicles are complex to say the least . All the warning light's , gauge's etc.... are controlled by a module an data network . GM class 2 serial data buss. Power windows also are controlled by a module . DDM - driver door module.
