It's more than the head. My Grand Marquis had a sensor in front of the
rad for outside temperature, one on top of the dash to see if the sun
was shining, and I think there was also one in the dash to sense the
inside temperature. If you're thinking of changing it, investing in a
manual may be worthwhile, so that you're sure of what's involved.
