1998 Mercury Mountaineer Problems

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 rear window wiper may not fully contact the rear window. To fix, replace both the wiper blade and wiper arm.

The rear wiper may stop working. This could be due to a rear wiper motor that has failed requiring replacement.
