2003 Ford Explorer 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.
A ticking noise may develop from the engine due to a cracked exhaust manifold. Damaged exhaust manifolds will require replacement to correct this 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.
