Ford Mustang GT Problems

A/C Fan Speed Changing Constantly

The 2010-2014 Ford Mustang GT with automatic climate control may have a problem with frequent fan speed changes when using the heater or air conditioner. This includes all performance models including the GT500, BOSS 302, GT, GT350, GT-H, and CA Special Ed.

Normally, the fan speed changes only to maintain a selected temperature, but when the fan speed changes frequently and needlessly, there is an issue with the fan speed control unit. 

The fan speed control unit, sometimes erroneously called the blower motor resister, regulates the speed for the blower motor in order to maintain the temperature set by the driver. When it fails, the fan will run at random settings, and the climate control will be inaccurate.

Note: this does not affect the temperature of the air that comes from the vents, it affects the amount of air that comes from the vents. 

The repair is simple, and quick. The control unit is located behind the glove box in most models, and removal and installation takes only minutes.

Also note: this only applies to vehicles with single or dual automatic climate control.

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.

Ford Mustang GT Reviews

I love my '09 GT. Of course, it has had a couple of issues, like a mysterous buzzing in the rear. I figured out that it was the trunk tension springs. I fixed the problem with felt spacers. I love the sound of this car. This is the fourth GT I've had and have loved them all. All had minor problems, but so has every car I have ever owned regardless of marque. Unless I hit the lottery, I...
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...
Noisy car due to duel exhaust,no mufflers. Also, V-8 4.6l engine not good on gas (esp in winter). And rear-wheel drive must have snow tires in winter for northern states. They are not cheap,so, get warranty. Seatbelt also no good. Pretty good sound for radio, adjustable driver seat also nice. Not enough room for big guys.
