    This could be a leak in your heater core. Do you smell a sweet smell when this occurs?

If it's not the heater core it could be that your carpet is saturated with moisture.I have a 1985 Monte Carlo SS and I had the same issue. I removed the carpet and found that it was wet underneath due to a leak in the door seal. You may have some luck by putting a heater in it with the windows open a bit to let the moisture out. Or try putting a De-humidifier in it for a night or two and see how much water is collected.

Hope This Helps..........Keep me posted with a comment here. Weather my suggestions help or not it's nice to know so i can pass it on if i have someone else with the same issue!..........thanks,,,,,six

White smoke from air vents while ac was on,greasy film on window while defrost is on/heater coil?


Yes. The heater core is leaking bad. The white smoke is the coolant and steam. Be sure to add water to the radiator before you burn up the engine.

if the "steam" leaves an oil film on the glass, your heater core may be leaking coolant.

Window fogging up


try cracking a window, or set the heater to pull in outside air, check your heater core for leaks. Heater core being my first thought, as the leaking coolent/steam will dampen the whole interior of the truck.

Smoke coming through air vents


Is it smoke? Or is it steam? If it's really smoke, it will smell like burning wires and you have an electrical short somewhere. You're going to have a fire unless it's fixed.
My guess is that it's probably not smoke or you would have already had a fire.
With that said I'm going to say that it's steam in which case your heater core (which is a small radiator located under the dash) is leaking coolant and the resulting steam is rising through the vents. The steam will have a sort of sweet and yes, a steamy smell to it. It will also leave a funny film from the radiator coolant coating the inside of the windshield.
The heater core should be replaced if my assumptions are correct.

Windows fogging inside car, maybe a vaccum leak?


If you feel warm air blowing up on your windshield and If your heater is working, I would guess its a coolant leak, probably the heater core. Usually a coolant leak will leave a kind of "greasy" fog that is more difficult to wipe off. It is basically steam coating your windows. You should be able to smell coolant if its leaking.
If no warm air is blowing, I would guess an issue with your heater control module or a vacuum problem of not supplying vacuum to move the plenum door.

Hope that helps.

My windows started to steam up do the moisture outsides and the rain,so I turned on the window defrost button and blast cold air,bu the windows kept fogging up further, I used the windshield wipers to...


to clear the interior of fog you must put the fan on recirc and #3 fan position.with the a/c on HOT.it will clear as soon as any heat from the engine is allowed to the heater matrix to dry out the interior.if you allow fresh air into the car with fogged up glass,they will get worse as the temp is warmer inside the car than out.(they collect condensation).
