All the gauges work except the speedometer and odometer. the horn won't work and the headlights won't turn on but all the other lights work. i checked all of the fuses, under the hood and the dash. could it be one connector that is making all 3 things not work? these are the only things that i have found that arent working properly except the blower motor only works on high, i thought that might just be a faulty switch though.
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:
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 ?
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:
In normal operation:
Headlamp Switch
The headlamp switch is a multi-position switch.
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:
For additional information, refer to Section 413-09 .

SOURCE: The gauges have stopped working ? Fuse under dash seems to be OK ?
Behind the dash is what they call a constant voltage regulator. It controls the guages. It's small and located behind the dash near speedo.
SOURCE: 2004 F250 No brakelights/turn lights on trailer
You will need to get a 12 volt test light and check the trailer connector for a voltage signal to the trailer, it may also have seperate fuses under the hood for the trailer lights if the system is factory installed, federal law requires the 2 systems be isolated, if there are blown fuses find the short in the trailer before replacing fuse(s), with no exceptions the short is always in the trailer. Hint, check the fuses 1st.
SOURCE: escort 55 van...lighting problems
Check Main power fuses in engine bay bolted onto front of battery. Some supply the central fuse box (drivers footwell). As the central box is sort of split into 3 main sections 80A 60A and 60A fuses supply the central fuse box Other fuses are 40A or 50A for cooling fan 50A heated windscreen (model dependent) and 50A glow plug (diesel). The central fuse box can be up latched from a metal clip right at the front above the narrow gap directly in front of the fuses themselves. With the central fuse box undone inspect all around wires for shorts. Also check to see if higher amp fuse had been put into lower amp socket and black arcing had occurred. Fuses may seem OK but connector is now fouled. F29 is 15A Interior lights, cigar lighter, Clock and radio. By the way Escorts were notorious for the stalk failing on the left hand stalk (Indicators and Headlights) Spray some good quality contact cleaner with the NEGATIVE BATTERY TERMINAL REMOVED as the substance is flammable and could spark while you carry our several on and off motions for penetration purposes. Got no idea of the year of your 55 van but wires to most Escorts which carry power to the instrument cluster illumination are as follows post 95 are Orange/yellow, Indicators (on stalk) Blue/Yellow and Blue/black, One side of fuel gage sender unit is Black/yellow and other is straight black to ground. Control Lights are Fuse 11 (10Amp) which supply most components in the instrumental panel this wire will be Violet/yellow and finally violet going into the instrument panel. .High Beam and indicators on separate circuit. Final illumination wire maybe Orange/blue. Check all sides for power is any of the wires have no voltage when lights on trace to faulty wire or fuse. Lastly in the fuse box there is a diode (well several) but if my memory serves me right it joins Violet/blue and violet/yellow which leads to the dip relay (standard check for short or open circuit) Cathode is side with silver stripe and black lead of multi tester. if1 or 000 is displayed on digital meter diode is faulty should read a figure eg 075 but that is not an actual reading but example. This is as accurate as I can remember and have some diagrams but remember there's a hell of a lot of wires some with the same colour there maybe 10 violet wires or 5 violet/yellow and not even remotely significant to one another. trace to fuse of control to be sure. Good Luck
SOURCE: 1998 ford contour blower motor not working
I have a 1998 Ford Contour. Believe it or not the ABS and the Blower Motor share the same fuse. It's a yellow 60 amp and you have to take off the battery to get at it. Of course this happened twice in the 6 years I had the car, both times in the dead of winter. Tires Plus in Pennsauken, NJ replaced it. Other than that, no complaints with my Contour.
SOURCE: Gauges, Power Windows, Auto Lamps radio interior lights dont work
Sounds like an ignition switch problem, maybe even at the key.
