20 Most Recent 2003 Ford Crown Victoria Questions & Answers


you need a new module. it costs about 300 to 400 dollars to replace. I had the same problem. First time the lights went off I was on the Pa turnpike. only way to handle the immediate problem was to hold the high beam knob on until you hear the click that the regular lights are back on. then release the high beams. until the problem occurs again. invest in the module its safer.

Does the cooling fan come on at 225F? Have the fan tested by the dealer with a scanner.

The fuse number for the compass light is fuse number 16 have you checked that?The fuse is located in the inside fuse box.

Passenger compartment fuse panel

The fuse panel is located below and to the left of the steering wheel by

the brake pedal. Remove the panel cover to access the fuses.

To remove a fuse use the fuse puller tool provided on the fuse panel
cover.
If the fuse checkes ok then either the Compass is defective or the tiny display light has burnt out.

I believe it will be up under the dash, to the right of the steering column. Here is a link to a picture, it was in reference to a light control module but shows the part your looking for as well.

Looks like the wiper motor uses G102 as the grounding point, should be close to the fuse box in the engine compartment. If you lift it and it stops then you may have a bad switch in the motor.

if you have to hit the solenoid with a hammer it's a sure bet that the starter is junk. however you can save cash by going to Napa or Oreilly's and and get the starter. don't go to a dealership part counter because it will cost you 3 times the amount. in order to be prudent just check to make sure the ground cable to the trans housing is tight this serves as the ground for the starter. good luck and please rate this..thanks

Which insturment cluster does your's have ? electronic instrument cluster or standard instrument cluster !

Standard insturment cluster - speedo / odometer
Speedometer/Odometer
The speedometer and odometer provides speed information based on a speed/distance pulse signal from the vehicle speed sensor (VSS). The VSS is mounted on the speedometer driven gear in the transmission.
Could be the VSS is bad .
Horn The horn system includes the following:
  • horn relay
  • horn
  • clock spring
  • steering wheel control switch harness
  • steering wheel pad horn switch, which is part of the driver side air bag module. For additional information, refer to Section 501-20B .
The horn is located behind the front bumper mounted to the radiator support.

Is the air bag light lit on the insturment cluster ? If it is the clock spring could be the problem . If not lit check the circuits from the horn relay .

VEHICLE RELAYS Operation Diagnosis .

Which headlamps don't work ? Low beams , high beams , both ?
  • The high beams are inoperative
  • Bulbs.
  • Circuitry.
  • Multifunction switch.
  • GO to Pinpoint Test C .
  • The low beams are inoperative
  • Bulbs.
  • Circuitry.
  • Headlamp switch.
  • Multifunction switch.
  • LCM.
  • GO to Pinpoint Test D .
Principles of Operation
NOTE: Due to varying wattage ratings and resulting current draw, certain aftermarket headlamp bulbs may cause the lighting control module (LCM) to shut down the short circuit protection, resulting in the low beams becoming inoperative. Verify that the headlamp bulbs meet Ford specifications.
Headlamp System The headlamp system consists of:
  • two aerodynamic halogen headlamp bulbs and retainers
  • headlamp switch
  • multifunction switch
  • lighting control module (LCM)
  • circuit wiring and circuit protection
In normal operation:
  • With the multifunction switch in the low beam position, power is supplied by the LCM to the low beam elements through the multifunction switch.
  • With the multifunction switch in the high beam position (forward detent), power is supplied to the high beam elements and to the high beam indicator in the instrument cluster.
  • When the multifunction switch is pulled toward the steering wheel, the flash-to-pass switch (part of the multifunction switch) is closed and power is supplied to the high beam elements. When the switch is released, they return to low beam operation.
  • The battery saver feature of the LCM will automatically turn off the courtesy lamps, demand lamps, headlamps, or parking lamps under the following conditions:
    • The ignition switch is in the OFF position.
    • The headlamp switch is in parking lamps ON or headlamps ON positions.
    • After 10 minutes.
Headlamp Switch The headlamp switch is a multi-position switch.
  • The positions include OFF, PARK, and HEAD.
  • With the headlamp switch in the PARK position (first detent), a signal is supplied to the LCM which powers the front parking lamps, the tail lamps, the side marker lamps, and the license lamp.
  • With the headlamp switch in the HEAD position, power is supplied to the headlamps through the LCM and the multifunction switch.
  • The panel dim switch (part of the headlamp switch) is located above the headlamp switch. The panel dim switch operates only with the parking lamps or headlamps on.
  • When the panel dim switch is held in the up position, the instrument panel lighting will progressively brighten.
  • When the panel dim switch is held in the down position, the instrument panel lighting will progressively dim.
For additional information, refer to Section 413-00 .
Headlamps On Warning Chime If the headlamp switch is left in either the PARK or HEAD position and the driver door is opened, the LCM will sound a headlamps on reminder chime when the following conditions occur:
  • The ignition switch is OFF with the ignition key out.
  • The driver door is ajar.
For additional information, refer to Section 413-09 .

Inspection and Verification
  1. Verify the customer concern by operating the system.
  1. Visually inspect for obvious signs of mechanical and electrical damage.

Check the timing. It may be off slightly. I would up the octane on an engine that big too.
