Do the headlamps work ? Are they bright ? Turn the key to start position ,do the headflamps dim ? I am assuming that when you turn the key to the start position nothing happens ! Starter doesn't spin . What engine size ? 4.0 or 4.6 L ?????
Do you know how to do automotive electrical system testing ? How to use a wiring diagram to find point's in the circuit to test from . When you turn the key to the start position a B+ voltage signal is sent to the PCM - engine computer , to signify that start is requested > If there are no problems with the anti-theft system the PCM will supply a ground to the starter relay . Has to have B+ voltage supply from fuse F2.29 10 amp in the central junction box . Voltage from this fuse goes to the park neutral safety switch an through to the starter relay if the park safety switch is good . Then there is the load or starter side of the relay , If the switch an relay are good an the pcm energizes the relay B+ voltage from fuse F1.12 a 50amp fuse goes to the S terminal on the starter solenoid .

There is one for the 2003 Mercury Mountaineer. If you are smellign a "vinegar" odor, mix a solution of 1 part bleach to 3 parts water and pour it down the grid at the base of the windshield. It will take care of the smell.

Check your brake fluid level first. If it is fine then you probably have a bad abs brake sensor.

2003 mercury mountaineer check charging system won't start


How can you decide if it is worth fixing if you have no idea what is wrong, it could be major or minor issue. Have it diagnosed before you decide. If it is not running the value of the truck is zip.

The mountaineer won't start. When i turn on the headlights the lights on the dash board goes dim and the gauges be moving fast.


Sounds like you have a low voltage problem.Take a volt meter and battery voltage first it should be 12-12.7 volts not running and key off.Then start engine and check the voltage coming out of the alternator it should be 13-14.7 volts.If one of these are not within these specs then replace which everone that is bad.

The rear brake lights won't go out no matter what we do. (2003 Mercury Mountaineer) We tried starting the car...putting it in gear...backing up...going forward...turning headlights on and...


You have a faulty Brake Light Switch, and it is stuck on.

Replace your brakelight switch. Until you replace it, you could pull the breaker out of the fuse panel in order to keep your battery from dying.
