Better yet, can someone tell me how to positively identify whether a truck has auto temp control on it when looking at a picture of the dash? Is it distinctly different than the 3 manual control knobs?

they started it as an option in 2001. In 2001 and 2002 it had three knobs and no digital display, but it said "computer climate control" on it I think, and the fan knob has like 30 positions (speeds) instead of 5.

in 2003 they changed to the digital display on the auto climate models.
