I just bought and picked up my newly purchased 2003 Ford F-250 Superduty XLT Sport Package. It has 120k on it. And I got it as a as is deal from NH. And the 4/wd wont work. It has the dial for a 4/wd shift. When I go to shift it into 4/wd it will not engage. And the 4/wd light does not show up on the dash. If you can help me on what this can be. If you know how to electrical test the switch can you let me know also. I will like ot be able to use the 4/wd since it came with a plow. I don't have power from the switch to the wiring on the transfer case. I am wondering if the switch is any good. THANKS! you can email me at eatmytailpipe@yahoo.com or just repost here.[/align]
