2004 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.

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.

Shuts down when on cruise control, idle goes up and down, transmission hits hard when shifting and one window does'nt work. Never again will i buy a ford product.

Seems Ford just started cranking out junk because things were selling well back then. Amazing the hood is rusting out already, the hood release cable jams the hood catch open most of the time you open the hood plus there is rusting under the body too.
