Exterior / motorized / adjustable mirrors not working

2002 Grand Marquis; the switch that operates the adjustable mirrors for the driver and front passenger doors does not opoerate the mirrors Could this be a fuse problem or relay. Or is something wrong with the switch itself. There mirrors have separate motors.So it has to be the switch itself, or a relay or a fuse. I'm thinking a common problem that other owners encounter.

Usually a bad switch would only fail in a couple positions..left to right both sides.if mirrors are completely inoperable I would look at a possible wiring concern, but I don't want to scare you, it could still be switch and they're comm

10 year old remotes go bad often, especially due to moisture retention.

Testimonial: "Thank you, yes both(2) remotes are bad. I found a testing machine at a local auto parts store, even with new batteries the remotes do not send signal."

SOURCE: Location of blower motor switch resistor on 2004 Grand Marquis

The blower speed controller is located under the hood on the right or passenger side on the heater housing just to the side of the heater hoses near the very back of the right cylinder head.
Yes that would cause the concern you are having.

SOURCE: 2002 Mercury Moutaineer-- Power window problem

Go through your fuse box and check for any burned out fuses also they may take a relay which may also be out. You can pick up a HAYNES or other brand repair manual at any auto parts store. Auto Zone sells mainly Haynes books, they will guide you to your repair in a step by step repair. The books are kind of like "repairs for idiots" they are really detailed and easy to follow.

Wing mirrors will not adjust

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 .

Which fuse controls front windshield wiper pump

Do the wipers work ? Fuse for wipers is same as washer pump .
Principles of Operation
The wiper motors receive inputs from the following:
  • Multi-function switch
  • Powertrain control module (PCM)
  • Ignition switch
  • Smart junction box (SJB)
The following components are integrated in the wiper motors:
  • Windshield wiper motor module
  • High/low speed relay
  • Run/park relay
  • Washer pump relay
  • Park sense (Hall-effect sensor)
Washer System
The windshield washer and the rear window washer are activated by the internal wiper motor modules when it receives a ground from the multi-function switch between the washer inputs. Depending on the correct ground, the internal wiper motor modules activate either the windshield washer or rear window washer relays (internal) by grounding the respective relay coil. When either module is activated, it connects voltage to the washer pump while the deactivated module provides ground to the washer pump. In this manner, voltage polarity is reversible to achieve directional change of the washer pump and washer fluid.
  • The washer pump is inoperative
  • Circuitry
  • Washer pump
  • Multi-function switch
  • Windshield wiper motor
  • Rear window wiper motor
  • Go To Pinpoint Test I .
Does your expedition have programmable/recall memory option for seats an mirrors ?
Driver Seat Module
The power driver seat and power exterior mirrors are controlled by the driver seat module (DSM) only when the vehicle is equipped with the programmable/recall memory option.
On the Expedition Limited, the power fold exterior mirror option is controlled by the DSM. Before running a self-test or retrieving codes, the power fold switch must be inactive for at least 30 seconds.
This is a complex vehicle , electronics , control modules an serial data communication networks. You mite be better off taking it to the dealer or some other repair shop . There could be DTC'S - diagnostic trouble codes stored in the SJB - body control module !

Normal Operation During normal operation, when the front wiper wash is selected, the windshield wiper motor provides power to the washer pump through circuit CRW14 (BU/WH) and ground is provided to the washer pump through circuit CRW12 (GY/OG) and the rear wiper motor. If rear wiper wash is selected, the rear wiper motor provides power to the washer pump through circuit CRW12 (GY/OG) and ground is provided to the washer pump through circuit CRW14 (BU/WH) and the windshield wiper motor.
    Possible Causes
  • Multi-function switch
  • Open in circuit CRW14 (BU/WH), CRW12 (GY/OG), CRW07 (GY/BN), CRW20 (GY/YE), SBB49 (RD) or GD149 (BK/GY)
  • Short to ground in circuit CRW14 (BU/WH), CRW12 (GY/OG), CRW07 (GY/BN) or CRW20 (GY/YE)
  • Washer pump
  • Windshield wiper motor

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 !

My side mirros dont work

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.
Driver Seat Module
The power driver seat and power exterior mirrors are controlled by the driver seat module (DSM) only when the vehicle is equipped with the programmable/recall memory option.
---------------------------------------------------------------------
Power Exterior Mirror Operation
The power exterior mirrors are controlled by the DSM and are operational all the time, whether the ignition switch is on or off. Using the power exterior mirror switch, the driver can adjust the driver and passenger exterior mirrors four ways.
