SOURCE: power windows stopped working on '03 mountianeer

There may be a relay or perhaps a switch to replace in the panel that houses the window switches on the driver's door. That panel comes off by prying it up from around the switches. You will see all the wires and perhaps the relay to replace when you pull it away from the door itself. The switches should simply unplug and you can replace whatever looks burned out.

SOURCE: air conditioner not working properly

I have just ordered the part to fix this. It is the A/C vacuum actuator (not sure why they call it a vacuum actuator because it is an electric actuator). It is under the dash on the driver's side close to the radio. There are two in the same area. It is the one closest to the floor. You can verify by taking it out (pull out duct that runs from center of vehicle to the outside to get better access), and actuating the vent by hand with the blower on to see if you now get air out the middle vents.

The part number is 1573596 from Rock Auto on the net. It cost $40.79.

    Where is the courtesy light switch in the drivers door on a 1998 Navigator


    courtesy light switch , is door ajar switch an it's part of the door lock actuator . Light on coming on ? Not going off ? The ajar switch is a input to the GEM module , fords BCM - body control module . The GEM will energize a relay to turn on the lights .
    The GEM will illuminate the interior lamps when any door is open or ajar. The interior lamps are; the dome lamp, the rear cargo lamp, the door courtesy lamp and the side rail lamps. The courtesy lamps will shut off when the doors are closed and the illuminated entry feature is not active or when the vehicle speed is greater than 5 mph (8 km/h). The interior lamps will not be reactivated until the vehicle speed is less than 3 mph (5 km/h) and a new door open warning lamp switch is received.
    The GEM controls the interior lamps illuminated entry function by activating the interior lamp relay.
    Mite be a good idea to have it check for DTC'S - diagnostic trouble codes .

    2000 navigator relay clicking and windows only work with dome light on when vehicle is shut off the dome lights flash for several seconds the wipers quit working also where do I start?


    All these components are controlled by a computerized module. You can try disconnecting/reconnecting the battery as this may reset the module. If no results you will have to have this modules operation checked for any codes/failures with a scan tool to possibly pont you in the right direction

    Principles of Operation
    Power Door Locks
    The generic electronic module (GEM) controls the power door lock and keyless entry system. Lock and unlock operation is achieved through the use of internal relays in the GEM. The relays are all door lock, all door unlock and driver door unlock. The normal path of the relays is to ground.
    Pressing the door lock control switch to lock or unlock sends a ground signal to the GEM. The same GEM pin is used for unlock and lock input. The unlock signal is a direct connection to ground. The lock signal is altered by an internal resistor in the door lock control switch. This varied resistance identifies lock or unlock command to the GEM.
    The door locks can also be controlled by the door key cylinder switches. For the liftgate door lock switch, turning the key to lock or unlock sends a ground signal to the GEM. The GEM will then ground the all door lock or all door unlock relay supplying voltage to the actuators. Turning the driver door key cylinder to the lock position sends a ground signal to the GEM. The GEM will then ground the all door lock relay supplying voltage to the actuators. Turning the driver door key cylinder to unlock sends a ground signal to GEM. The GEM will ground the driver door unlock relay and supply voltage to only the driver door actuator. If a second unlock ground is received within three seconds of the first, the GEM will ground the all door unlock relay supplying voltage to the passenger door actuators (if 2-stage unlock is equipped).
    Keyless Entry
    The keyless entry remote transmitter sends a signal that is received by the GEM internal antenna. Depending on the signal received, the GEM module will ground the appropriate internal relay and lock all doors or unlock the driver door. If the unlock signal is received again within three seconds of the first unlock, the GEM will ground the internal all door unlock relay unlocking all doors. The lock and unlock relay output to the actuators is controlled by the GEM, the same as power door lock operation from the control switch.
    If the signal received is for the panic button, the GEM will cycle ground to the park lamp relay coil and horn relay coil. The park lamps and horn will continue to cycle until the panic button is pressed again or the ignition switch is turned to the RUN position, or after the timer expires.

    Fuse or what


    Your multifunction switch on the steering column controls your exterior lights. The GEM module controls the interior lights and other stuff. If bad, it would not blow fuses. WHich fuse blows?
    Your Ford dealer might be familiar with this issue, so call the service dept and ask them and get a quote. It may be wiring.
    reoprt back.

    • The high beams are inoperative

    Principles of Operation
    Generic Electronic Module (GEM) The generic electronic module (GEM) receives inputs from the following:
    • door ajar switches
    • liftgate ajar switch (wagon)
    • liftgate glass switch (wagon)
    • headlamp switch
    • keyless entry keypad switches
    • the powertrain control module (PCM) (vehicle speed signal)
    • ignition switch
    • remote keyless entry transmitter
    The GEM uses these inputs to control the output to the battery saver relay and interior lamp relay. Both relays are integral to the central junction box (CJB) and cannot be accessed directly.
    Interior Lighting Systems The GEM grounds the battery saver relay and interior lamp relay coils when any door ajar switch or the headlamp switch is closed. The interior lamp relay then supplies power to the interior lamp circuit. Vehicle speed must be less than 15 kph (9 mph) for the GEM to ground the interior lamp relay. The interior lamps will remain illuminated for a period of up to 25 seconds after all doors are closed or until the ignition is switched from the OFF position, or the GEM receives a vehicle speed signal. Actuating the interior lights from the headlamp switch will operate at any time.
    Illuminated Entry Illuminated entry is activated when a keyless entry keypad switch provides ground on the GEM input or when the GEM receives an unlock signal from the remote keyless entry key fob. The GEM then provides ground to the battery saver and interior lamp relay coils. Illuminated entry is deactivated when the GEM receives a lock signal from the remote keyless entry key fob or if the GEM receives ground inputs from the keyless entry keypad switch lock code. Illuminated entry will also be deactivated when the GEM receives input voltage from the ignition switch.
    Battery Saver The battery saver is activated when the GEM is not receiving voltage input from the ignition switch (off position). The GEM will then provide ground to the battery saver relay coil for a maximum of 30 minutes depending on the state of the interior lamp switch inputs to the GEM. The energized battery saver relay switches voltage to the demand lamp circuit and the interior lamp relay coil. After time-out, the GEM removes ground to the battery saver relay disabling the demand lamp circuit.
    Puddle Lamps The puddle lamp relay operates reverse from the battery saver relay and the interior lamp relay. The puddle lamp relay coil receives voltage when the ignition switch is in the START or RUN position, which disables the circuit to the puddle lamps.
    Inspection and Verification
    1. Verify the customer concern by operating the system.
    1. Visually inspect for obvious signs of mechanical and electrical damage.
