Known Problems

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.

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 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.

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.

The gears for the timing chain can strip, causing the engine to crank but not start.

Failure to change the power steering fluid can cause the fluid to become gray with metal particles. The contaminated fluid can damage the power steering pump resulting in a growling noise when the wheel is turned; the damaged pump will require replacement to eliminate the noise.. Life of the power steering gearbox and pump will be shortened if the fluid is not serviced regularly.

On higher mileage vehicles, one or more EGR orifice in the intake manifold may plug with sludge. This can cause the engine to misfire when first accelerating because too much exhaust gas is directed into the cylinders where the orifice is not plugged. Cleaning the clogged passages should correct this concern.

The EGR orifices in the intake manifold may plug with sludge. If the truck has high mileage, this may cause engine misfire when first accelerating because too much EGR gas is directed into the cylinders of the unplugged orifices. This makes the mixture lean, which causes a gradual stumble that increases in severity until repaired.

Tubes for the EGR system (exhaust gas recirculation) can break, causing an exhaust leak and noise under the hood.

If there is a vibration or noise at highway speed, it could be from the frontdrive shaft and may require replacement of the double cardan joint. A double cardan joint is a type of driveshaft joint that uses two universal joints.
