2004 Mercury Mountaineer - Page 4 Questions & Answers
Was driving my 2004mountaineer tool light came on and jumped out gear now won't do nothin bug grind
There are several possibilities. If you have a 4x4, the unit could be between the 2 wheel drive and 4 wheel drive modes. There is also a 4 wheel drive low and 4 wheel drive high mode. On some models the selector switch is similar in appearance to the blower motor selector switch. Someone could reach for the blower speed and turn the 4 wheel switch instead.
Another possibility can be a burned out led indicator switch on models which use electric shift solenoids to position the drivetrain between 2 and 4 wheel drive. The voltage gets messed up because of the burned out bulb and the shift plunger does not go into the correct position.
