Known Problems

The engine oil pan gasket can develop a leak. Leaking oil may accumulate on the exhaust system resulting in a burning smell. Replacing the gasket should correct this leak.

The battery light may illuminate on the instrument panel because the alternator wire harness connector is damaged. A new connector kit is available and should be installed to correct this concern.

If a noise from the rear end is heard when going around turns or after driving at highway speed for an extended period, this could be caused by a failing differential clutch kit. An updated differential clutch kit available.

Intermittent rough idle may be caused by the EGR sensor sticking, causing the EGR valve to stay slightly open. The valve and sensor must be replaced together to correct this concern.

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.

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.

If a noise from the rear end is heard when going around turns or after driving at highway speed for an extended period, there is an updated differential clutch kit available.

A ticking noise may develop from the engine due to a warped exhaust manifold. Damaged exhaust manifolds will require replacement to correct this issue.

Catalytic converters can go bad and potentially plug the exhaust, hurting engine efficiency and performance.

An oil leak may develop from the the right side head gasket.  Oil from this type of leak will commonly drip onto the starter. Our technician tell us an updated head gasket is available to correct this concern.

The front brakes may stick, bind, or grab. This can happen when the front brake caliper pins become corroded. Cleaning or replacing the caliper pins will be necessary to correct this problem.

Intermittent rough idle may be caused by the EGR sensor sticking, causing the EGR valve to stay slightly open. Our technicians tell us the valve and sensor must be replaced together to correct this concern.
