What would cause smoke to come from the vents of a 1991 Cadillac DeVille?
Check the Heater Core? Did it smell like oil or antifreeze. My Heater Core went, started blowing out smoke from the vent. Most Likely the Problem. "smoke" poured into my 1991 when the ac blew out all the freon and froze up the outside temp gage.

Smoke is coming through the vents of your van Then the ac quit Could there be a connection?
The smoke is most likely a leak in prestone. Is the antifreeze level going down? OR, if the smoke has stopped, then something blew on the a/c. and now there is no more freon.
What is causing the air to come through the defroster vents and not the AC vents in a 1995 Ford Mustang GT when the AC or vent knob is turned on?
I am sorry, I am not technical on this stuff, but we had the same problem on our 95 Mustang GT. We had to take it into the dealer and the problem was that one of the hoses had come loose, so it was not blowing enough air pressure to force the vents open.
