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.

2001 Mercury Mountaineer RecallsRecall 07V336000
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.
Ford has recalled certain 1999-2001 Explorer, Explorer Sport Trac, and Mercury Mountaineer vehicles for a possible binding speed control cable. If the cable binds, throttle return could be affected, causing a sticking accelerator. Dealers will inspect the cable and replace it if necessary.
