Side mirrors do not operate

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.

On the '04 MDX the mirror adjustment selection switch has to be in the middle position of L & R, for the mirror to re-adjust when the car is in reverse. I hope this helps.

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

remve teh black plastic cover from the door then remove the door panal undo the conector if its power mirror remove 3 10mm nuts revers for instolaton

Could have a DDS an PDS .depends on what RPO code yours has >
Outside Mirror Description and Operation (with RPO DL3)
Or
Outside Mirror Description and Operation (without RPO DL3)
Without
Heated Outside Rearview Mirror Operation
The REAR DEFOG relay controls the operation of the heated outside rearview mirrors. When rear window defogging is requested, the REAR DEFOG relay is energized and B+ is applied to the supply voltage circuit of the mirror heater element, located in the mirror face. A constant ground is also applied to the mirror face. Current will pass through the mirror heater element, warming the mirror, so long as the rear window defogger is commanded ON.

With
Heated Outside Rearview Mirror
The DDS and PDS control the activation of the mirror heaters. Upon receiving a serial data message indicating a request for heated mirrors, the DDS and PDS, will apply voltage to the mirror heater element supply voltage circuit. The mirror heaters will remain active until a new message is received indicating rear defogger is to be deactivated.
The power mirror system consists of the following components:
• Driver Door Switch (DDS)--An electronic control module with integrated switches and requires programming when replaced
• Passenger Door Switch (PDS)--An electronic control module with integrated switches, requires programming when replaced
• Power Mirror Direction Switch--Integrated into DDS and is a four position momentary switch that provides a signal input to the DDS for up, down, left/extend and right/retract with a mirror switch activation
• Mirror Select Switch--Integrated into DDS and is a three position switch that allows the operator to select the left or right mirror and also a neutral/fold position
• Mirror Extend/Retract Switch--Integrated into DDS and is a two position switch that allows the operator to select the mirror extend or mirror retract position
• Left Outside Power Mirror--Contains both the vertical and horizontal mirror motors
• Right Outside Power Mirror--Contains both the vertical and horizontal mirror motors
• Body Control Module--An electronic control module that requires programming when replaced, serves as the power mode master and is the main message handler
• Horizontal and Vertical Position Sensors, if equipped with memory mirrors--Supplied a 5-volt and low reference by the DDS/PDS and provide a variable voltage signal to the DDS/PDS that is proportional to mirror position
• Folding Mirror Motor, in each of the outside mirrors, if equipped with power fold mirrors--Provides extend and retract movements of the mirror and is serviced as a complete mirror assembly
Your best bet mite be to take to a qualified repair shop , i really don't think you'll be able to do anything with it.
Do you have wiring diagrams so you know which wires to test ,do you know how to do electrical testing ?
The Driver Door Switch (DDS) and Passenger Door Switch (PDS) supply voltage to the outside rearview mirror heater elements upon receipt of a serial data message from the HVAC module indicating that the rear defrost system is active. The door switch supplies B+ through the driver/passenger mirror heating element supply voltage circuit when a request is seen. Ground is applied through the driver/passenger mirror heating low reference circuit.

First, make sure you do not have the mirror control switch in the "neutral" position. If it is, neither mirror will work. If the switch is in the correct position to operate each mirror and neither of them work, the next thing I would check would be the MIRRORS fuse (2 Amp) located in the Body Control Module Fuse Block under the right side of the dash near the blower motor. If the fuse is blown, you probably have one of your mirror circuits shorting to ground. In this case, I would replace the fuse and see if it blows again when I operate each mirror. If one side works and the fuse blows when trying to operate the other side, then you at least know which mirror circuit is shorted and you can diagnose accordingly. If the fuse blows immediately (without operating the switch), or if the fuse is not blown, then you most likely have a defective mirror control switch or a broken wire in the umbilical that goes between the body and the driver's door.

Do you know what DTC'S - diagnostic trouble codes are ?
DTC B1023
Circuit/System Description
The driver door switch (DDS) and front passenger door switch (PDS) each contain switches that control power door lock and window functions. The DDS also contains the control switch for the power outside rear view mirrors. These switches are integrated within the door control modules and are not serviceable as separate components. The DDS and PDS monitor these switch inputs for internal faults and set B1023 00 if any are detected.

You could have any number of problems an without testing , hooking up a scanner that can check DTC'S in the door module ,electrical circuit testing etc... we'd only be guessing . Your best bet mite be to take it to a qualified repair shop.

The exterior mirrors:

• are controlled by power controls on the LH front door trim panel.
• are of a foldaway design.
• may contain turn signal indicators.
• may be heated when the heated back window glass is activated.
• may have a programmable recall memory option.
