Anyway, it ´s fully loaded (strobes, siren, radio, bars, Motorola Workstation, radar etc.) and I ´m using it as a show car. Beside it is my daily driver. The people love it at U.S. Car Shows which are very popular in Europe (photo).
About one year ago the headlights started to go on and off as they liked together with a "Click" noise. First I ignored the problem and put some extra wires to the headlights together with fuses and a seperate switch.
That helped for several month but then one evening I couldn ´t switch off the instrument cluster lights anymore. They went off by themselves over night. Shortly after that I had a total shutdown of the lighting control module (LCM) - no turning lights, no parking lights, no dome lights, no instrument cluster lights, even the key reminder signal was dead - only the brake lights were working - and so I replaced it using a brandnew LCM (I think it was a 2006 manufactoring date).
From then the headlights stayed on but after 3 months, when I started the car in the morning, the headlights went on at the same time - but just for a moment - and went off again when the car was running. Once the horn honked and the headlights flashed for a sec during the starting process.
Shortly after that I had a total malfunction of the new LCM as I had had with the old one: Suddenly all the lights were dead - no turning lights, no parking lights, no dome lights, no instrument cluster lights, even the key reminder signal was dead. Only the brake lamps were working - so I replaced the LCM once again, this time I used a 2008 module.
But some days later there was the problem again: I heard a "Click" during daylight driving and then I realised that the headlights were on - then they went off after some time. Two times at night the LCM went double "Click!" and the instrument cluster lights went off and on within a second. Twice, without the lights on it went double "Click!" and the horn honked by itself - nothing but trouble.
The best thing happened two days ago: The dome lights stayed on, then they started to glow and suddenly the airbag lamp flashed and stayed on! After starting the car once again the airbag lamp went off and the dome lights stayed also off.
I have also realised that the brake lamps failed from time to time. I don ´t know if this has anything to do with it, but this problem started at the same time together with the LCM / multifunction switch (MFS) troubles.
I thought that it might be the brake switch but I ´m not so sure anymore...
I know that the brake lamp cable goes through the MFS.
Here in the forum you can read that you should change the LCM and the multifunction switch. So I did so, I exchanged the MFS (by using a used one, with generation 2 serial number) yesterday, but this didn ´t help either!
On my way home I heard the familiar "Click" again and the instrument cluster lights flashed once within a second as usual. The brake lamps are working normal at the moment. Now I ´m waiting for the total blackout which is going to come, I ´m quite sure and I ´m afraid of night driving.
Do you think that I should buy a brandnew multifunction switch or is this a different electrical problem?
The unmotivated activation of the horn is maybe a hint.
Does the horn cable go through the multifunction switch as well?
Could it be a short circuit somewhere in the steering column?
This really makes my sick, because I have spent already a lot of money and I still can ´t trust my lighting system during night rides.
I have been driving old Fords (1971 Ford LTD Sedan, 1971 LTD convertible, 1978 Ford LTD II, 1977 Ford LTD Hearse, 1993 Mercury Grand Marquis) since 1994 but this is one of the most annoying problems I have ever had. Seems that the newer Fords don ´t have the same quality anymore...
So one question comes in my mind: Have you driven over a Ford lately? I think in that context this would be the right solution...
So I really need some good suggestions - thanks a lot for reading my long text and best regards from Austria!
have the same problem?
