    4WD switching on and off!

    Okay, I use my 4wd very rarely, and I have high mileage. The last time I put it into 4wd it had a tendency to change in and out of 4wd, A4wd, and 2wd on it's own. Someone I spoke to told me that there is an electronic switch that needs replacing that controls this. Does anyone here have any...

    Not in park??

    Lack of lifted expeditions??

    I've always loved the look of a 4x4 on large swamper tires, cruising by me on local roads. Why do we not see more expeditions lifted up? And why is it hard to find product info on lift kits on this site? Do most of you not wish to ride high? Don't get me wrong, some things are meant to be...

    Passenger window?!

    What would be the first thing to check if my rear driver side power window won't respond to my driver's door control? All the other windows open and close with no problem. The one in question does not move, or make any sound at all. Would this be a motor thing?
