2008 Lincoln Mark LT Problems

Blower Motor Only Works on High

The 2006-2008 Lincoln Mark LT with manual temperature and fan controls may have problems with the the blower motor only blowing air on certain settings. Most commonly the fan will only run on the highest setting. This is a well documented problem, and is caused by a failing blower motor resistor.

Correcting the problem is straight forward, and requires replacement of the small resistor. The resistor is normally found behind the glove box, next to the blower motor.

Ticking Noise From Engine

A ticking noise may be noted from the engine caused by one or more stuck or collapsed valve lash adjusters. The repair involves inspecting and replacing lash adjusters as necessary.

Spark Plugs May be Difficult to Remove

Our technicians tell us the spark plugs in the 5.4L V8 engine can be very difficult to remove. Ford has issued a service bulletin (08-7-6) to address this issue, which includes a recommended procedure on how to remove the plugs. Failure to follow the recommended procedure can result in the one or more spark plugs breaking off in the cylinder head.

The recommend procedure is as follows. Using this procedure will greatly reduce the chance of breaking a spark plug.

1. Break the spark plugs loose when the engine is warm.
2. Turn each plug 1/8 to 1/4 turn and soak the treads with 1/2 to 3/4 teaspoon of Motorcraft Carburetor Tune-Up Cleaner or a quality penetrating oil. Do not try to remove the plugs at this time.
3. Let the threads soak for at least 15 minutes.
4. After the soak period, tighten and loosen each spark plug, working it back and forth until the turning effort is reduced. Then, you can remove the spark plug.

There are special tools available to remove the broken spark plugs and repair shops will often charge additional labor time, over and above the quoted spark plug replacement cost, for the removal of each broken spark plug.

When shifting from 4WD to 2WD the truck sometimes goes back into 4Wd partially (3 answers)

The 2WD does not always stay engaged, sounds like it is partially in 4WD and I have to recycle several times, sometimes it will then stay in 2WD.
