2002 Chevy Tahoe power side view mirror issues

so did not scan the PCM to learn why it fails?
we never ever skip scans today modern cars MUST be scanned first
after fuses all good (endless posted here same words )

outside mirror electrics seen in the service manual
I am reading it now
left side front fails
the mirror runs off the DDS, model, driver door switch controls
so mirror left//right up down work but the fold motor is dead

well the DDS is bad or the wires to it are bad
or comms fail. not scanning the PCm/BCM means not seeing errors.
the DDS has 4 switches
2 for extend and retract
and 2 to drive the motor, so 4 wires there. can fail.

I say DDS is bad. or connectors rusty or wiring damage there.

puddle fuse ???? Puddle light's on door rear view mirrors ? I can't find the center instrument fuse box ? Doesn't have one in the center . Has two - one right an one left
Fuse Block - Right I/P
On the lower right side of the I/P
Fuse Block -Left I/P
On the lower left side of the I/P
These are not what your looking for any way .

Exterior Courtesy Lamps
The SEO 1 15 A fuse in the engine wiring harness junction block supplies battery positive voltage to both the exterior courtesy lamp relay switch contacts and the exterior courtesy lamp relay coil circuit. When the driver or passenger door is opened the body control module (BCM) energizes the exterior courtesy lamp relay. Current flow is from the exterior courtesy lamp relay to both outside rear view mirror exterior courtesy lamps. The exterior courtesy lamps are grounded at G200 and G203. When the remote function actuation (RFA) module receives a door unlock command from the remote function actuator transmitter, the RFA module will send a message to the body control module (BCM) indicating that an UNLOCK command has been received. The BCM must have inputs that indicate that the ignition switch is OFF, all the doors are closed. The BCM will activate the exterior courtesy lamp relay illuminating the power outside mirror exterior courtesy lamps. If the door locks are activated to the LOCK position, or if the ignition switch is turned to either the ON or RUN position the exterior courtesy lamps will deactivate immediately.
When an outside door handle is lifted or a door is opened, the exterior courtesy lamps illuminate.
I would think maybe a relay problem , not a fuse . The exterior courtesy lamps relay , located in the relay block body . Relay Block -Body
Under the left side of the instrument panel near the left kick panel
If this doesn't fix the problem you need to have a qualified repair shop that has a factory or professional type scan tool view code's in the BCM - body control module .
DTC B2643
The SEO 1 15 A fuse in the engine wiring harness junction block supplies battery positive voltage to both the ground illumination relay switch contacts and the ground illumination relay battery positive voltage circuit. When the driver or passenger door is opened the body control module (BCM) energizes the ground illumination relay. Current flow is from the ground illumination relay to both outside rear view mirror ground illumination lamps. The ground illumination lamps are grounded through the courtesy lamps relay at G200 and G203.
DTC B2642

Hi Michelle , what make model an year vehicle ? On some vehicles this is function is controlled by a door module .

In order to control outside rearview mirror operations, as well as other door functions, the front door modules must be powered up. For this purpose, battery voltage is supplied from the rear fuse block, through separate circuits, to each front door module. Each front door module is separately grounded through a ground stake. The front door modules also use these power and ground supplies to drive the mirror motors, and to provide power and ground to window and lock switches and door lock actuators. In addition, the driver door module (DDM) uses these power and ground supplies to power the driver door switch assembly (DDSA) and integral mirror control switches.
Could have DTC'S - diagnostic trouble codes stored in BCM - body control module .

The switch is a contact type. When you move the switch it complete the circuit by connect the two contacts points. After some time the switches wear out simply replace the switch.

sounds like a new switch is needed , 15 years of use is not bad going

The following is from 2002 Honda Odyssey factory manual page 20-70: Driver's switch panel removal. (This is the switch panel to the left of the steering wheel with TCS, cruise control, mirror, and sliding door switches.) Gently pull on the driver's switch panel bottom right corner to release the (2) right side clips, then detach the remaining (2) clips on the left side and the single top center clip. If equipped, disconnect the cruise control main switch connector, TCS switch connector, power mirror switch connector, and power sliding door connector, then remove the panel. Once the panel is removed, you can push out the switch from the rear. The switch has two bulbs in it, one is the cruise switch backlight bulb and the other is the cruise control function bulb.

Power windows an locks work ok ? Do you know anything about automotive electeronic control modules ?
Power Mirror System
Power Mirror System Components
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 4 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 3 position switch that allows the operator to select the left or right mirror and also a neutral/fold 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
• Memory Switch, if equipped with memory mirrors--Supplied power by the DDS and provides a voltage signal to the DDS upon a switch activation
• 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
• Powertrain Control Module (PCM), if equipped with memory mirrors--An electronic control module that requires programming when replaced and provides the message indicating transmission gear selection
• Driver Information Center (DIC), if equipped with memory mirrors--Part of the instrument cluster which is a an electronic control module that requires programming when replaced and is used to personalize the memory recall functions
• Fold 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
Each of the outside power mirrors contains 2 reversible motors to provide horizontal and vertical movement of the mirror glass. The vertical motor operates the up and down directions and the horizontal motor operates the left and right directions. If equipped with power folding mirrors, each outside power mirror will contain a reversible fold motor to operate the extend and retract functions. Each of the mirror motors are circuit breaker protected.

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.

If the drivers side does absolutely nothing, there is a chance that power plug that goes into the door has come apart. There is a rubber boot that goes from the cab to the door, that is where the wires run. The power plug is usually right before the boot or right after.

check releys and wires in door jam 1 might be broken failing that u need a new switch

the door panel near the mirror must be removed if not the entire door panel inside u will find 3 nuts to remove to get the old mirror off. hope this helps please rate me
