Are we talking in-car temperature sensors or outside temp sensors?  The 
5000 has two outside air temp senspors, one at the front grill and one in 
the plenum at the base of the windshield.  It uses one in-car sensor at 
the middle of the dash top pad.

The 5000 is completely vacuum driven except for the temp door inside the 
module which is driven by an electric servo motor through a bowden 
cable.  The cable BTW is prone to failure (since you can't push on a 
rope) but it is very easy to replace and only a couple bux at the dealer.
