Sounds like an exhaust leak either at manifold or collector pipe. Exhaust is being sucked in through fresh air intake for hvac system. Must scan to determine what code is setting check engine light.

I would check the connection on the back side if the turbo some time that clamp fails and the down pipe losens up you can get some fumes that way or check the other end of the down pipe it could be leaking there. a good way to tell if it is leaking on the back side of the turbo is look for black around the clamp.

Air vent schematic


air for the inside of the car comes from the vent at the base of the windscreen or is recirculated inside the car
if you see what appears to be mist, fog or smoke from the ac vents ,it is extra cold air from the ac system that is seen as fog when it hits the air in the car
you will know exhaust fumes by the smell

Exhaust smell coming in from vent


In most cases fumes coming into the cabin thru the vents is from a leak near the engine. If the exhaust is leaking around the engine it should be fairly loud.

I have a 2005 Ford Escape - this past week have noticed exhaust fumes coming in through the heat vents- has been very cold here - could it be something frozen or another problem?


chec the entire exhaust area for leaks or smells--cold will often break worn parts--dont use car till its fixed--carbon monoxide is 200 times stronger than oxygen

Fumes escaping from ac vents inside vehicle while driving and leaves a film residue on inside of windshield whenever the heat or defrost are used.


Hello dedunwoodie.
Your heater core is beginning to leak coolant.
As the fan blows through it it is picking up the liquid and depositing it on your windshield.
It will need to be replaced to solve your problem.

MPV 2002. Black particles come out from air vents


I get the feeling this is the first time you've used the heater? Its probably accumulated dust. As long as you don't get a burning smell or smell exhaust fumes you should be ok after a few hours use.
