    I Think we got the problem solved.

    We took the cables off for a few seconds from the battery and pushed the numbers on the key pad on the driverside door, from 0 to 6, The doors all locked, we open them up again and the lights inside the car went off and also sprayed the switch inside the door.

    We have been watching for over 24 hours and didn't notice any lights going off or on.

    Thanks so much for giving us a push in the right direction.

    Thats more than the Ford Garage did.

Just bought sh 1999 Ford Focus - at 45mph traction control light flashes.

The light flashes because the module that controls the system is detecting a fault, you need a scanner hooked up and then drive it and record the results. Yes that takes a dealer or a very well equipped shop.

2000 Ford E350 van has the lights staying on with the light switch off and the key removed. Is there a relay that could be causing this or would it be the switch?

Call ford. There is a massive recall on lighting control modules. My '03 Crown Vic started having the headlights come on with the switch off in the daylight. If it's not covered under the recall, you can repair this module by obtaining and replacing 4 ice cube relays on the board inside. I had already bought the relays to fix mine when I learned of the recall. Ford dealer did all the work for free. If you have to replace the relays, they were about $12.00. Better than the 350.00 for a new lighting control relay. By Ford's own admission, 97% of the problem with these is the failure of the mechanical relays of one or more. There are you Tube videos showing how to do this repair if you get stuck with it...

the garage for not reading the fault codes and you paying for guessing
the light is showing a fault and reading the fault codes would have shown that fault
now there is an engine control module on the fuel pump that could be the problem take it to a specialist diesel shop and have the codes read

Gas and Theft light comes on when pressing the break.

Cluster warning lights

Whenever this warning light or any other stays on in the dash it is indicating that the systems control module (or the system sensor in the case of lights like low oil pressure, door open indicators etc.) has detected a fault, it then disables the system (this applies to ABS,TCS, TCM, SRS and BCM faults and others) as long as the light is on. You must now have the dealer hook up a special electronic diagnostic tool and "scan" the system for the fault code that is stored for the problem(s)

Ford Focus Engine Light Comes on, the next day turns off again

When the service engine soon light (Also called the check engine light) is turned on this is to alert you to the fact that powertrain control module (computer) has detected a failure somewhere in the systems it controls, this can be the transmission or the engine or emission system, there are fault codes set in the modules memory for these faults. What needs to happen now is to have the powertrain control module scanned with a special tool called an OBD2 electronic engine control scanner or a OBD2 code reader. Once the code(s) are read then you must perform the diagnostics for each code and make the appropriate repairs based on the findings of the diagnosis that was performed, this is called doing "Pinpoint" testing.

Headlight will not come on, high beams will not come on , the passing lights work, brake lights work. and then randomly the headlight will start to work

You most likely have a failing Lighting Control Module. Search the Internet for "Crown Victoria Lighting Control Module" and you will find hundreds of references, from how to repair it yourself (requires soldering and technical expertise) or how to replace (reasonable cost of $100-$200) or how to buy replacement modules on eBay, and other sites.
