1998 Mercury Mountaineer ProblemsHeater Stuck on Hottest Setting Due to Broken Heater Blend Door
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.
A rattling noise from the engine may indicate that the timing chain cassette is worn. Our technicians tell us that installing an updated cassette and timing chain tensioner should correct this concern.

1998 Mercury Mountaineer RecallsRecall 06V286000
Ford has recalled certain 1998-2002 Explorer, Explorer Sport Trac, and Mercury Mountaineer vehicles for an issue with the driver's seat recliner mechanism. The upper bolt that attaches the recliner mechanism to the seat back frame could fracture. If this happens, the seat back could fall backward and disrupt the driver, possibly causing an accident. Dealers will replace the upper bolt and, on some vehicles, replace a lower bolt as well.
