2005 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 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.
The intake manifold O-ring gaskets commonly leak, causing stalling and poor idle quality; the Check Engine Light will illuminate.

2005 Mercury Mountaineer Reviews
Very reliable and nice to look at. Comfortable and quiet. The only problem I had with it was one of the back windows stopped going down. Quickly repaired by the dealer. Hasn't had a problem yet I've had it for a year and a half. I recommend it to anyone. Just if ur going to buy it used completely check and test it out before signing anything.
