2005 Ford Mustang GT Problems

Blower Motor Only Works on High

The 2005-2009 Ford Mustang GT with manual temperature and fan controls may have problems with the the blower motor only blowing air on certain settings. This affects the Mustang Bullitt, Shelby Mustang GT350 and Shelby Mustang GT500 as well. 

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.

Squeaking noise while turning due to worn outer tie rod ends

If a squeaking noise is heard while turning the steering wheel, the outer tie rod ends may be worn and should be replaced.

Spark Plugs May be Difficult to Remove

Our technicians tell us the spark plugs in this 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.

An interesting car. Car still has its original tires and the original battery and wiper blades were changed out in 2013. I bought this auto trans car from the original owner back in 2011 with 6k original miles. It was kept in a garage, covered, still smelled and looked new but it kept killing the battery. I bought it for a song after totaling my 1998 GT but that's another story. Did some r...
Best car I have ever owned. A few minor issues in the first year with TSB's which were fixed by dealer. Only routine maintenance, a couple set of tires, a battery, front brakes, and thousands of gallons of gas in over 100,000 miles of pure driving pleasure.
Nothing but problems with throttle body after the warranty was up. Rocking sound system but burned cd's skip to the point that they can't be played at all. Beautiful car but will not buy another one.
