Mystery : link between A/C compressor, "D" Drive position and fuse#15 under dashboard

Hello everybody,

I'm new on lincolnforums and I'm French, so forgive me in advance for my possible mistakes


I explain the situation because I really despair with this car and I hope you will have a solution for me.
Here , I realized my dream by purchasing a Lincoln Town Car limousine 2003. ( I've always been fascinated by American cars , especially those outsized !)

But shortly after I had purchased wholesale electrical problems : after a short circuit my LCM , my air suspension unit , my PCM , my dashboard grilled and my driver panel that controls all electrical equipment back ... As if that was not enough , I bought this limousine without knowing it lacked ALL climation system , so I do not risk to get some fresh air!

So I bought a new radiator , condenser, evaporator, compressor and two temperature sensors .

The car has spent more than 4 months in the garage and it was the longest , the most unpleasant and most expensive of my life (I 'm only 21 years).

I thought I was finally out of the woods after spending € 3192 Hand mechanic work + € 1,500 auto parts . But apparently not !

I only discovered today that my air conditioning compressor and all the air conditioning works very well ( same engine running) but as soon as I go into Drive mode, the compressor stops and so I no longer have cold .
Looking at my fuses under the dashboard, I noticed that the number # 15 of 15 amps (which manages the multi -function switch and turn signal by the the user manual) blow out systematically as soon as I walked in position "Drive", but not in "Parking" or "Reverse" position.

Looking at my fuses under the dashboard, I noticed that the number # 15 of 15 amps (which manages the multi -function switch and turn signal after the user manual) grilling systematically as soon as I walked in Drive but not in Parking or Reverse.

I tried several times by changing the fuse, and it's the same thing, it burn when I 'm Drive position and cut the air conditioning compressor ! What I do not understand is that the user manual indicates that manages the "multi function switch" and "turn signal " So , what is the relationship with air conditioning ???


Finally , my other problem (as if I did not have enough! ) , My headlights go out alone randomly while I drive ! While the LCM has been changed , what is the problem ? ( Relay ? )

Thank you very much for all the answers you can give me .
Oh, to clarify , I Live in French ( Bordeaux) so there is NO Lincoln dealer nor France , nor even in Europe so I turn to you who have used this brand , you are my last hope !

Cordially

Welcome.

Unfortunately, I don't think anyone is going to be able to give you quick answers to your problems, but only guidelines for troubleshooting.

First, I commend you for not putting a larger fuse to compensate for the blowing fuses. That causes fires, which kill people in limos, so it's great you are not doing that.

Do you have the actual shop manual for your car? You need the wiring diagrams to find out exactly what is connected to that 15amp fuse that could add more load when you switch to drive. Since you car had everything removed and re-installed, you need to confirm that the mechanic didn't wire something extra into the circuits. It's a real problem when you have to suspect that non-standard work caused the problem.

As for the headlights, it sounds like you have yet another bad LCM. Did you get a brand new one, or a used one?

Thank your for your response TownCars1,

I would not risk putting greater than those specified fuses since it is partly because of this that everything had blown. I was riding with a 20 amp fuse for the dashboard while the manual stated maximum 7.5 amps for example, my previous mechanic troubleshooting had put it to arrive to start the car ... I saw that it did ... He was totally incompetent.

LCM I ordered on Ebay was also used, but as I live in France costs referrals and shipping are high, not to mention the French customs.

I have the manual for the 2003 Lincoln Town Car provided on the official website of Lincoln, and I have some electrical schematics for Limousine by Royale Limousine but nothing that exactly corresponds to the fuse box. I just know that this fuse # 15 is the "multi-function switch" and "turn signal" referring to the owner's manual.

It sounds to me that you don't have the complete shop manuals. It sounds like you have the very simple owner's manual. Since you are in France, and away from mechanics that know Lincoln, you absolutely much purchase a copy of the full shop manuals. They are big books, and they are not that expensive, but invaluable for solving this issue and future issues cost effectively. With the manuals, if you find a friend that knows electrical engineering in detail, they can help you if you have those manuals. Something like this:

Yes, you need a new LCM is my opinion. And it seems that Lincoln has come out with an improved one, and they will pay you back the money you spent on replacing it when you have the symptoms you described.

Thank you for links, I do not even know there was such a complete manual!

But about new LCM, I do not see how Lincoln will pay me while I live in France and they are not present on the territory ?

Worth a try to contact Lincoln to see if they will help you. Try emailing them.

But maybe your limo has more than 150,000 miles, since high mileage would be common for a limo of that age.

Also you should join LimousinesOnline.com

Your limo is common there and when you have problems they will help some so this place is not your last hope.

Keep in mind that you really have 2 cars glued together. The front and back are really just a Town Car. The limo companies make as few changes as possible to the original car before they weld another vehicle in the middle. That is why you need the normal shop manuals and the manuals from Royale.

Ford/ Lincoln are unreachable by email because in the forms they ask for example ZIP code and I do not have because I'm not a U.S. resident, and I can not call them because I do not speak English! (Thank you Google Translate ) I have no chance to get anything from them especially for a small module like the LCM! It doas not matter.

My limousine has 200,000 actual kilometers, but the dashboard that I had bought used shows 223000 km because it is from another Town Car damaged, but its true mileage is 200,000 km, it is not huge for an engine like this one!

Thank you for website link, it's interesting !

Still worth a simple effort to try to email. Use zip code 10010. That is New York City. The closest thing we have to Paris here.

Hello,

After verification,
I'm guessing that he was the fuse number 14 (which manages transmission control switch, LCM, decklid AND A/C clutch relay!) and not the fuse 15 ! So the link between the different components is obvious!

The question remains as to why when I go into drive mode, this fuse blows, even when the air conditioning is off.

I searched various forums on google and one of them spoke to check the "inhibitor switch" on automatic transmission but it was a Nissan.

Do you have a synonym for "inhibitor switch" or something that corresponds to the automatic transmission of the Lincoln Town car? Because in translate in French I cannot find an equivalent !

I have an appointment Monday with my mechanic but if I can find some more information that may help us always!
