2002 grandcherokee power windows,mirrors,locks will not respond when useing the control buttons but other components such as power seats,moonroof,overhead instrument panel all seem to work fine

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.

Check the wire bundle coming in to the door at hinge side. It is a short or broken wire

Power mirror switches are usually located on the driver's door armrest forward of the power window and door lock switches, but some Troopers have this control mounted on the center console behind the shifter lever.

The power windows on your vehicle are controlled by an electronic control module , as are the power mirrors !
Power Window System Components
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)

Your best bet , take your vehicle to a qualified repair shop.

Sounds like the master switch is not plugged in properly, this is the switch in the driver's door.

Do you know anything about automotive electronic's , control module's , using a factory or professional scanner to communicate with said control modules ? Here is a list of componets involved in controlling the power windows ,lock's , driver an passenger door mirrors .
Power Window System Components

• Driver door module (DDM)
• Passenger door module (PDM)
• Body control module (BCM)

• Door lock switches in driver and passenger doors (switches are integral components to the DDM and PDM)

I don't think the switch would be the problem , more then likely broken wire's inside the flex boot from the body to the driver's door . See this more often then the switch going bad . Just replacing parts could get expensive . I would think a power wire or a communicate network wire broke .

How To install Replace Power WIndow and Lock Switch 2002 09 GMC Envoy and...
Free wiring diagrams here http://www.bbbind.com/free_tsb.html Enter vehicle info. year , make , model and engine size. Under system click on body & accessories ,then under subsystem click on power windows or power lock's ,doesn't matter . Click the search button ,then the blue link . Tell me if you think you know whats going on here . Do you know what class 2 serial data network is ? It is a module to module communication network .

Do you know anything about automotive electronic's ? Serial data Communication network ? Electronic module's inside the vehicle doors , communicate commands ! No relay ,no fuse .
If the passenger mirror is selected and a direction switch is activated, the DDM sends a serial data message to the PDS indicating that the passenger mirror was selected and the direction to be commanded. The PDS will then supply battery voltage and ground to the appropriate control circuits for the direction selected.
DDM - driver's door module

Door Lock System Components
The power door lock system consists of the following components:
• Driver door module (DDM)
• Passenger door module (PDM)
• Door lock relay--Located in the instrument panel (I/P) fuse block and controls the locking of the rear doors.
• Door unlock relay--Located in the I/P fuse block and controls the unlocking of the rear doors
• Body control module (BCM)
• IP BEC
• Reversible door lock actuators in each door

Power Window System Components
The power window system consists of the following components:
• Driver door module (DDM)
• Body control module (BCM)
• Passenger door module (PDM)
• Rear door power window switches
• Power window motors in each of the doors (circuit breaker protected)

Your best bet , take it to a qualified repair shop that has a diagnostic scanner that can pull code's an view input data form these systems . There is one circuit breaker for the window's an fuse's for the lock's . I would think a data network problem . But that would be a guess , without testing anything is possible on these .

CHECK FUSES FOR POWER WINDOW,CHECK FUSE FOR POWER MIRROR AND CHECK FUSE FOR POWER DOOR LOCK.IF FUSE OKAY DOOR CONTROL MODULE FAULTY ITSELF.

have you checked what voltage the vehicle is ?/ many vehicles from japan are 24 VOLTcheck that first
