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.
Heater in 2003 crown vic stays on always ???? Blower motor ? Air blowing out vent's all the time ?
Blower motor speed control module .maybe ! If that is what your taking about . Can't turn blower motor off .
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
What popped ?????? Any light's lit on the instrument cluster , Air bag ? Do you know how to test automotive electrical circuits using a voltmeter ? How to read an understand electrical wiring diagrams ? Free wiring diagrams here http://www.bbbind.com/free_tsb.html Enter vehicle info. year , make , model and engine size . Under system click on engine , then under subsystem click on speed controls . Click the search button then the blue link . Do you know what a speed control servo is ,an what it looks like ? It's under the hood in the engine compartment . In the second diagram you'll see it an it's wiring connections . Check power and grounds for the servo. an switch input's . In the first diagram you see the switch ,inside the switch you can see different resistors ,You can test these input's to the speed control servo with a voltmeter . Check out some videos on youtube on electrical testing speed control systems an test the system .
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 .
The horn system includes the following:
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 .
Which headlamps don't work ? Low beams , high beams , both ?
The high beams are inoperative
GO to Pinpoint Test C .
The low beams are inoperative
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.
The headlamp system consists of:
two aerodynamic halogen headlamp bulbs and retainers
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.
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
Verify the customer concern by operating the system.
Visually inspect for obvious signs of mechanical and electrical damage.
