1999 Mercury Mountaineer Problems

Heating & Air Conditioning -- Verified

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.

Electrical & Lights -- Verified

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.

Miscellaneous -- Verified

The rear window wiper may not fully contact the rear window. To fix, replace both the wiper blade and wiper arm.

Miscellaneous -- Verified

The rear wiper may stop working. This could be due to a rear wiper motor that has failed requiring replacement.

Engine -- Verified

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

1999 Mercury Mountaineer Reviews

I bought my 1999 Mercury Mountaineer with 52000 miles in 2003. I currently have 245,700 miles on the vehicle. It has the original water pump and alternator. I've replaced the brakes on it, the A/C Compressor clutch and oh yeah the A/C has never had to be recharged! Almost unheard of these days! I've pulled a 28 foot travel trailer with this vehicle coming from Georgia up through the mountains and difficult countryside in New Hampshire. The vehicle runs and drives as good as ever. I recently put new lower ball joints on it as one of them was a little loose. Not bad for a quarter of a million miles.This vehicle is without a doubt the best vehicle I've ever owned and I've owned over 20 different cars and trucks! LOVE MY MERCURY!
