Side Mirrors problem

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.

You have a short in the wiring of that fused circuit, or less likely that one of the mirror motors has a short. A short is an unintended path to ground, like an exposed wire touching body metal, or an internal motor failure. If that fuse is only for the mirrors and nothing else, it will be easier to find. A likely place will be in the door openings where the wires can get stretched and chafed. Pull the protective boot away from the wires where they enter the door, and check carefully. You may need to get to the mirror motors and to the switch for them. If everything looks okay, better get a multi-meter to check sections of the wires for continuity. A wiring diagram will be needed to find the right color wires that you will be looking for. I am guessing that each motor will have 4 wires to it, 2 for side to side, and 2 for up and down. These 4 wires will come from the switch on the driver's door that operates them. Power travels from the fuse to the switch, and then to the mirrors, as the switch operates them. The ground wire for the mirrors will originate at the switch, or it may be a shared common ground at the driver's master switch for the mirrors and the power windows. The short may be in any of these wires, or in the switch (evident at the connector to the switch as melted plastic, perhaps), or a short in one of the mirror motors. Good luck and good hunting.

Check for voltage on the vertical power output at the switch when operated. If no voltage, try lubricating the switch contacts. Still no voltage? Replace the switch.
If there is voltage, open the mirror assembly and check for voltage there. Is there voltage? Do you hear the motor sound when you operate the switch? If you hear a motor sound but the mirror does not move, it is a mechanical problem which can be easily fixed. If there is no motor sound despite the presence of voltage, the vertical axis motor has burned out or seized. Try lubricating the mechanism and, if still a no-go, replace the motor or the entire mirror assembly.

If the mirrors only move down and not up I would suspect the mirror switch , the mirrors use one motor to move the glass up and down,and another motor to move them in or out , and if the mirrors move down the motors are working.the only other possible problem would be a wiring but highly unlikely due to the fact that the turning the motors in a different direction is done by switching the polarity to the motor which requires both wires to be good to make the motors move in the down direction ..check the mirror switch I am sure you"ll find that"s your problem

Usually there is a switch issue. The switch that allows you to select right, left or nuetral can go bad or get dirty and not allow power distribution. If you feel comfortable doing so, remove the trim and gain access to the switch. Using a test light or the schematics, find out which wire is the voltage supply and ensure it has power with the key in the on position but the motor need not be running. If no, suspect a fuse issue, if yes then suspect a switch issue. You can use a jumper wire to apply power to the mirror feeds (again a schematic would be greatly reccomended) and if the mirrors move, viola! I hope this helps

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.

sounds like a switch as common error oboth sides unlikely

hey
it could be a bad switch if they both malfuntion the same way the only thing they have in common is the switch so most likely the switch.bad plug can also cause this.
