2003 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 rear window wiper may not fully contact the rear window. To fix, replace both the wiper blade and wiper arm.
The intake manifold O-ring gaskets commonly leak, causing stalling and poor idle quality; the Check Engine Light will illuminate.

2003 Mercury Mountaineer Reviews
I bought a brand new 2003 mercury mountaineer and have had to replace the transmission 3 times!!!! COSTING THOUSANDS OF $$$$!!! The first time, it only had approximatly 50,000 miles on it and was just out of warranty. The second time, it had approximately 100,000 miles on it and just out of the 2 year warranty. The 3rd time, it had approximately 130,000 miles on it. I will NEVER purchase a mercury mountaineer again. In fact, the manufacturer should give me my money back!

Its been a great car for 107,000 miles.Have replaced one hub bearing and routine maintainence.Excellent in the snow.We have towed two different boats with it,a 17 foot bayliner and a 20 foot bluewater cuddy the car survived and so did the wife.
I have a 2003 mercury mountaineer with 189,xxx miles on it and it has been a great truck. Just had to have the transmission rebuilt for the first time. Other than the transmission which was my fault for running mismatched tires with an all wheel drive system it has needed just regular maintainence and 1 hub bearing.Truck is great in the snow and big enough for family i would recomend it to anybody.
Just bought this with 112,000 miles. Took it to mechanic for evaluation, invested $1,200 in suspension and rear axle bearings. The vehicle is very comfortable and plenty of power in the 4.0 V6.
My son on his way to Navy in Florida reported the transmission 1 & 2 gear went out in Alabama. It would move in 3rd, drive and reverse. Oh it needs a rebuild of the transmission $ 3,000.00. The transmission SHOPS report this is common problem with the transmission. Hmmm Ford why not stand behind your vehicles, recall them so we get what we pay for. When you know you have a part defect, correct it in a timely manner before more fall victim.
