2003 Mercury Mountaineer Problems

A cosmetic crack may develop on the plastic liftgate trim panel. Our technicians tell us the Ford has released a service procedure to replace the applique without damage the the liftgate glass.

A failed heater blend door or actuator can cause the temperature control for the HVAC system to stop working. A clicking sound from the dash area would commonly indicate an actuator fault. If the heater gets stuck on the hottest setting, the heater blend door may be broken requiring replacement of the heater box to repair the issue.

The composite (plastic) intake manifold may crack near the thermostat housing and cause a coolant leak. Ford released an updated manifold that was reinforced to prevent a recurrence. No recall was issued for this problem but Ford did extend the warranty to seven years on some models from the date of purchase.

This vehicle has nice features and it is comfortable to drive. That's where the positive stops. In the five years that I have owned it, the air conditioner has stopped working 4 times, over 4 consecutive years (not a good thing in Arizona). The CD player has quit working 3 times. The rear hatch window became disengaged and shattered. Months later the rear hatch cracked down the middle. The gas ...

The transmis...

I AM IN THE PROCESS OF CONTACTING MERCURY ABOUT MY REAR HATCH WHICH ALSO HAD THE PROBLEMS WITH THE STRUT CAUSING MY REAR HATCH TO SLIDE DOWN AND SHATTER THE GLASS (ALL OVER MY 13 YEAR OLD DAUGHTER). MY TRANSMISSION IS ALSO JERKING WHEN IT SHIFTS. MINE IS A 2003 AWD AND IT HAS 115,000 MILES ON IT. THIS IS BULL AND I AGREE THAT FORD NEEDS TO DO SOMETHING ABOUT IT.
