congratulations on your first time. i used to have problems with my electronic 4wd switch, but mine wouldnt disengage. my first time was with my 93 s10 blazer which had a sunroof. i put the windows up and opened the sunroof. went boggin through a big mud pit near one of my hunting spots. even with the windows up i still got mud in my vehicle through the sunroof, landed on my shoulder and center console. good job again.
