    thanks captmanny

    moving mirrors by hand they are quite firm

    I feel it has something to do with the switching as both sides are affected

    do not have a wiring diagram of remote mirrors

    jeep will not supply any drawings



    regards

Sounds like striped gears in the unit. Try moving the mirror by hand they should not have any play. Good luck.

Mirror has power ,but won't move up,down,left or right


It is possible that the actual "mover" or motor is not working or is not connected to the mirror properly. Can you hear the motor activating when you try to move it? If yes then check the mirror is attached correctly and nothing has broken away. If no (and it may be very difficult to hear it ) then the actual motor may be broken.

Dodge 3500 Diesel power mirrors work side to side but not up or down


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.

Memory seats adjust on there own as well as mirrors


BCM has nothing to do with this function , MMM - memory mirror module !
Memory Mirror System Operation
The MMM is capable of storing mirror position for 2 different drivers. Mirror position is determined by both horizontal and vertical position sensors in each of the power mirrors. The MMM supplies a reference voltage and a low reference to these sensors and determines mirror position through the horizontal and vertical position signal circuits.
The MMM receives power through the battery supply voltage circuit and the MIR/LOCK fuse and a constant ground source. Any time that battery voltage is disconnected and then connected from the MMM, the MMM will enter the mirror relearn mode. The mirror relearn mode can also be commanded using a scan tool. Refer to Memory Mirror Module Learn for further information.The memory switch receives power through the battery supply voltage circuit and the MIR/LOCK fuse. The MMM upon receipt of a memory switch signal input, a class 2 message from the SIC or a class 2 message from the PCM indicating that the transmission is in park, will then supply battery voltage and ground to the appropriate power mirror motors through the mirror motor control circuits to move the mirrors to the predetermined positions.

DTC B1586, B1596, B1616, or B1626
The mirror horizontal and vertical position sensors are potentiometers. The Memory Mirror Module (MMM) provides these sensors with a 5 volt reference circuit and a low reference circuit. The MMM monitors the horizontal and vertical position sensor signal circuits which change values based on mirror position. These voltage values are used to determine mirror position and can be set into memory. When the MMM receives a memory recall request, the MMM will control the power mirror to the memory position based on the horizontal and vertical position sensor signal values.

Install a scan tool.
Turn ON the ignition, with the engine OFF.
With the scan tool, observe the mirror horizontal and vertical position parameters in the Memory Mirror Module (MMM) data list.
Operate both the left and right mirrors through the full range of movements.
Does the scan tool indicate that the left and right mirror horizontal and vertical position parameters are within the specified range?

Memory Seat System Components
The memory seat system consists of the following components:
• Power seat switch assembly
• Memory recall switch assembly
• Horizontal adjuster motor
• Front vertical adjuster motor
• Rear vertical adjuster motor
• Recline adjuster motor
• Memory seat module
• Memory mirror module
• SEAT 25A circuit breaker
• MIR/LOCK 3A fuse

Your best bet , take it to a qualified repair shop !

2001 explorer sport trac side mirros not working"


did you check power mirror fuse? if ok, remove your power mirror switch at the driver side and clean the contact area, take a test light and check all wires for good connection. one by one test the voltage output,-/+ by pressing the switch, if all wires have output -/+ , and mirrors still not working, remove the switch connector, find out the three wires going to power mirror and direct it to - and positive voltage alternately, if the mirrors move, repair the wire that cut on the moving area, if still not moving repair or replace the two motors inside the mirror

Electric Mirrors do not work (Drivers & Passengers)


There are two power wires to the DDM - drivers door module .Both are orange ,one is powered by a fuse DDM fuse 15amp . in the left I/P fuse block , plus LT DOORS 25amp circuit breaker .
Power Mirror System Components
The power mirror system consists of the following components:
• The driver door module--Class 2 module with integrated switches and requires programming when replaced
• The passenger door module--Class 2 module with integrated switches, requires programming when replaced and also contains the RFA receiver
• The power mirror direction switch--Integrated into DDM and is a 4-position momentary switch that provides a signal input to the DDM for up, down, left/extend and right/retract with a mirror switch activation
• The mirror select switch--Integrated into DDM and is a 3-position switch that allows the operator to select the left or right mirror and also a neutral/fold position
• The left outside power mirror--Contains both the vertical and horizontal mirror motors and is serviced as a complete mirror assembly
• The right outside power mirror--Contains both the vertical and horizontal mirror motors and is serviced as a complete mirror assembly
• The body control module--Class 2 module that requires programming when replaced, serves as the power mode master and is the main message handler
• The DDM 10A fuse--Located in the I/P fuse block and is hot at all times
• The PDM 10A fuse--Located in the I/P fuse block and is hot at all times
• The memory switch, if equipped with memory mirrors--Supplied power by the DDM and provides a voltage signal to the DDM upon a switch activation
• The horizontal and vertical position sensors, if equipped with memory mirrors--Supplied a 5-volt and low reference by the DDM/PDM and provide a variable voltage signal to the DDM/PDM that is proportional to mirror position
• The park neutral position switch, if equipped with memory mirrors--Provides transmission gear selection information to the PCM and is used for memory recall and mirror tilt in reverse functions
• The powertrain control module, if equipped with memory mirrors--Class 2 module that requires programming when replaced and provides Class 2 message indicating transmission gear selection
• The driver information center (DIC), if equipped with memory mirrors--Part of the instrument cluster which is a Class 2 module that requires programming when replaced and is used to personalize the memory recall and mirror tilt in reverse 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 are ? Diagnostic trouble codes
DTC B1544, B1600, or B1605
DTC B1580, B1590, B1610, or B1620
• If DTC B1580 is set by itself, the left horizontal position sensor signal circuit maybe open, shorted to ground or battery
• If DTC B1590 is set by itself, the left vertical position sensor signal circuit maybe open, shorted to ground or battery
• If DTC B1610 is set by itself, the right horizontal position sensor signal circuit maybe open, shorted to ground or battery
• If DTC B1620 is set by itself, the right vertical position sensor signal circuit maybe open, shorted to ground or battery.
• If DTCs B1580 and B1590 are both set, the left 5 volt reference or low reference circuit(s) maybe open, shorted to ground or battery.
• If DTCs B1610 and B1620 are both set, the right 5 volt reference or low reference circuit(s) maybe open, shorted to ground or battery.
Need a factory scan tool to test !
Install a scan tool.
Turn ON the ignition, with the engine OFF.
With the scan tool, observe the mirror horizontal and vertical position parameters in the Driver Door Module (DDM) and Passenger Door Module (PDM) data lists.
Operate both the left and right mirrors through the full range of movements.
Does the scan tool indicate that the left and right mirror horizontal and vertical position parameters are within the specified range?
0.50-4.75 V.
Your best bet , take it to a GMC , Chevy , buick or cadillac dealer

Right Hand mirror doesn't retract


i would check the switch first and also the passenger side door jamb wire harness also i know it sounds simple but ALWAYS check ALL of you fuses before beginning any electrical fault tracing, try removing the switch and identify which wire powers the mirror and manually jump power with a paper clip to the mirror in question there should only be three wires one will have power and the others will be left and right mirror retraction if this works your switch is bad if not go to the mirror and power that manually and if no dice you got a bad motor -jeff

Electrical Problem


I would operate one by one mirrors left-right,radio, electric locks.
I would first dont operate side mirrors and observe if fuse remain then leave radio disconected (dont power on or remove its wire harness). If with radio disconnected fuse is not blown, i would use electrical locking and test again.
Good Luck
