I have a 1990 trooper 2.8L V6. I have had it now going on 3 years and it never came with a owner's manual. I figured out how to engage and disengage the 4wheel drive, but I have a winter and power botton's just below the shifter, which is on the floor. I don't know what they do. Can someone help??? Also have looked around on line to try and find a OWNER'S manual, and can't seem to find one. I do have the repair book already but it doesn't give as much info as you would think it should. If anyone has an idea where I can get one, that would be helpful. Thanx

If you have a shop repair book you should have more than enough info. they usually run about $40 on ebay.
