Ford F-150 Problems
RepairPal has identified the most common problems with the Ford F-150 based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
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.
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.
A ticking noise may develop from the engine due to a warped exhaust manifold. Damaged exhaust manifolds will require replacement to correct this issue.
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.
Catalytic converters can go bad and potentially plug the exhaust, hurting engine efficiency and performance.
New TSB may be available
According to Ford Bulletin 06-04-04
Some 2003 + INDEPENDENT REAR SUSPENSION (IRS) AXLE F-150 vehicles equipped with a 9.75″ or 8.8″ limited and Mustang vehicles equipped with limited slip rear axle, may exhibit a chatter, shudder, a binding sensation, or a vibration during low speed turns. On 4X4 vehicles, the sensation may appear to be originating from the front axle or the steering gear.
First verify the condition. On 4X4 trucks ensure that Modifier (XL-3) for fifteen (15) minutes prior to the vehicle is in 2WD, to isolate the rear axle. If the condition is verified to be in the rear axle, replace the limited slip clutch pack.
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.
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.
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.
