The sunroof may leak and the problem is the little drain ports may be clogged.

Checking and adjusting the AC compressor clutch air gap can extend the service life of the AC compressor.

Do not use air filters with oil-coated elements. They may cause premature failure of the mass air flow sensor; this is not covered under the warranty.

   A frozen shift lever may be caused by either a bad brake switch or a broken gear lever mechanism. If the switch is bad it will not send the correct signal to allow you to shift. The solution is to replace the switch. If the switch is good, you will most likely have to replace the shift lever mechanism itself.

A vacuum leak from the PCV grommet vacuum leak can cause the Check Engine Light to illuminate. The molded rubber hose connections may crack and collapse, causing the vehicle to run roughly. A damaged PCV hose will require replacement.

Erratic engine coolant temperature or intermittent overheating can be caused by corrosion inside the water pump. The impeller may spin on the water pump shaft or the impeller may corrode. Either condition reduces coolant circulation resulting in engine overheating.

Due to age and possible damage during removal, it is recommended to replace  the spark plug boots when replacing the spark plugs,

Check the battery cable ends frequently for corrosion. Corrosion can easily migrate under the cable insulation and cause numerous electrical faults and drivability issues.

An exhaust leak may develop in front of the catalytic converter. This type of leak should be corrected as soon a possible to avoid damaging the catalytic converter.

A cosmetic crack may develop on the plastic liftgate trim panel. Lincoln has released a service procedure to replace the applique without damage the the liftgate glass.

Incorrect cabin temperature can be a result of a broken temperature blend door. Our technicians tell us if this occurs, the complete heater case will need to be replaced.

In high dust areas, problems with the EGR system are common. The filter for the EGR solenoid may plug and cause the EGR to activate when it should not; this can cause the engine to stall. The dirty filter should be replaced to correct this concern.

When replacing the battery, make sure the battery height is correct; a battery that is too tall can cause a short circuit when the hood is closed.
If you experience poor running and low fuel economy after the starter has been repaired, it could indicate that an incorrect starter relay was used. A diode-suppressed starter relay may be needed.
Even though the manufacturer does not call for regular servicing, our technicians recommend servicing the power steering fluid regularly.
