A malfunction has been detected with the Anti-lock Braking System ( ABS )
could be a fuse , an ABS sensor , or some other problem
* in my case , the ABS light suddenly came on and the first ABS fuse that I
checked was not installed all the way . I touched the fuse with my finger ,
heard a " click " and the ABS light went out ( just lucky I guess , but also
suspicious of how that could have happened )
An ABS fault.
A malfunction in the air bag system has been detected
On a 2002 Mercury Mountaineer : The " check gage " light comes on if the engine coolant temperature is too high , the engine oil pressure is too low , or the gas gauge is at or near empty
If the ((ABS)) Light is on then it's a good thing indicating that the Antilock brakes sensor is in good condition. I too have a 2002 mountaineer
I bought a used 2003 Mountaineer in November come to find out that the AC doesn't work. I have added freon but still blows hot air. I bought a rebuilt AC compressor off Ebay and will have it installed soon.
If you are going over an uneven surface, the light may come on because one wheel is spinning faster then the others.
A door panel on a 2004 Mercury Mountaineer is held on by several screws. Once all the screws are removed the panel can easily come off.
One of your front wheel hubs is bad and the ensor is sending a bad reading to the computer.
It didn't come with a cabin filter.
the blend door actuater is bad
The 1999 Mercury Mountaineer either has the ( 4.0 liter Single Over Head Cam , V6 engine or the 5.0 liter V8 , which is an over head valve / pushrod design engine ) Helpfull
Your engine oil could be low check it when it cools and if level is fine your oil pressure sending unit could be bad or engine in need of rebuilding
