#4 of 35 Mercury Mountaineer
Feb 26, 2008 (6:36 pm)
I recently discovered that when I used E85 fuel in my 2003 "Flexfuel" 4.0 V-6 Mountaineer, it destroyed the spark plugs in about 5000 miles, watered down the oil to the point of irreparable engine damage and gave me poor gas mileage. The vehicle was under warranty and the complete motor, throttlebody and fuel pump were replaced. The dealer advised me not to use E85 fuel anymore unless I switch to a synthetic motor oil, Why? I use regular gasoline now and get much better mileage anyway.

I have a 2006 Mountineer with 42000 miles on it and the Instrument Cluster went on it and my child was stranded in MA. I had to spend $500 for parts and labor because my bumper to bumper warranty was up at 36,000. The service at the Ford dealership in Great Berrington MA was horrible. Has anyone else seen this electrical problem in any of their vehicles before?
#6 of 35 Light Issue
Sep 13, 2008 (6:20 am)
I have a 2000 Mercury Mountaineer. When you turn the head lights on and have the fog lights on, the fog lights do not work at all. Also, the turn signals will not work with the fog lights on and the headlights on. I could only get the turn signal to work with the running lights on. Another thing is that with the lights on and the fog lights on, the left headlight/ fog light would be really dull. and the left turn signal light stays on.
I was wondering if anyone else has had a problem like this or if they have any ideas.

#9 of 35 Headlight adjustment
by le roy

I have a 2000 Mountaineer. I want to adjust the headlights. I opened the access flap and notices there are two adjustment screws(?). Facing the passenger side light, there is one in the upper left and one pretty much in the middle of the housing on the right. I would like to make the beams a little higher and am not sure which one to adjust.
Does anyone have any photos?

Been like it for years (about six now) for our 99 Mountaineer 4.0 Liter - pretty much as soon as it was off warranty of course.
The green LED segments on the display fade in and out and for the most part now are off most of the time now. So you never know which radio station you are on until they call it out.
Apparently it is a common electrical fault (have heard exact same complaint from otther owners on line) but the dealers of course prettend like they know nothinng about it.
As you may have guessed, after six years with it I have given up on getting it fixed.
In any case I have a new more serious issue - the car is not recognizing my key. So while it opens the electric lock doors and cranks the engine, the "Theft" indicator remains on and so will not allow the engine to start. This used to be intermittent (approx once every 50 starts and was temporary. Now it is permanent!
If other Ford makes are this reliable - no wonder they have lost market share.
#11 of 35 My 1999 Mountaineer cranks but will not start!
Jan 18, 2009 (8:12 am)
The car cranks well despite the current cold snap but will not start.
I noticed that even with the key in the ignition that the "Theft" light is still flashing just like when you lock the car up. The owners manual says that this indicates it is not recognizing my key and if flashing will not allow the car to start.
This used to be intermittent (approx once every 50 starts and was temporary. Now it is permanent!
Next step for me is to try and find the spare key to see if that one works.
Anyone else have the same issue?
If so, did it mean getting the key re-programmed at the dealer or was there some other fix?
Any suggestions welcome
#12 of 35 2002 Mountaineer - Front Power outlet not working
Mar 29, 2009 (12:33 pm)
I have a 2002 Mountaineer and the front Power Outlet has stopped working. there is also one for the rear seat that works fine and another hidden one under the rubber mat in the center consile that works as well. I've pulled and checked fuse number 24 and it looks perfect. Is there a fuseable link under the console? something else I need to check? I've attempted to remove the console buy haven't found all the screws yet.
Any help would be appreciated.

I have a 2000 with a tach that works intermittently. The shop they would have to send it in and it would cost a lot. Any ideas?
