Ford F-150 Problems

A/C Fan Speed Changing Constantly

The 2009-2014 Ford F-150 with automatic climate control may have a problem with frequent fan speed changes when using the heater or air conditioner. This includes F150 Harley Davidson, King Ranch, SVT Raptor, FX2, FX4, Platinum, Lariat, and STX editions. 

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 2004-2014 Ford F-150 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.

little or no heat in cabin

Turned on heater and got cold air. set it to 90 and the the temp guage got to half and only got a small amount of heat. vehicle started to have windows fog had to turn on A/C to clear them. It was working fine just two days ago last time used.

I leased a 2015 Ford F150 in February 2016. At this moment, it has 6164 miles on it. Last week, I left my house to run errands and got about 5 minutes from home. I stopped at a stop light and when I accelerated to go, the truck started shimmying and I lost acceleration. Thankfully, I was at a place that I could pull over and get off the street. I turned off the truck, sat for about 5 minut...
