Re: 2000 Cadillac Seville STS

luvmy, Do a search for "aspirator" and "cabin air temperature sensor".
You're looking for the procedure to R&R the sensor and tiny muffin fan behind the 1" square grille just left of the steering column. You go in through the panel at the left (door) end of the instrument panel, the one with the round window duct sealer which mates with the door duct. Listen at the grille during cold start.

If that's not the problem, then look for the A.I.R. secondary injection pump, located in the l/f fenderwell, used to light off the cat on cold start.

Move this up to Seville..............fairly common problem.
