SOURCE: Exhaust fumes in car when heater is running and car is at a stop.

Hi, What you have is a leak in the exhaust system. What you need to is take the vehicle to a repir shop (anyone that can weld) Drive the car up a ramp, and start it, you will see the fumes emitting from the hole in the exhaust and entering the heater ventilation system(thats how its getting in the car) simply weld the leak shut. Ps It can also be the exhaust manifold gasket that needs replacing, check for a leak first.

SOURCE: exhaust fume check light

Is the car juddery when you start?  The same light came on mine with power loss issues at higher revs and it was really juddery- it was the coil pack.  Was replaced at the garage (don't take it to the main dealer they WILL rip you off) in half an hour.

Sounds like you need to do a A/C deodorizing kit. May be able to find one at your local parts store. Or, run your A/C without your recirc, and hope the mildew gets off the EVAP core. It is possible you have a dead mouse in your heater box if it smells really bad.

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

What is it when gas fumes comes through the vents

You probably have an exhaust leak up by the exhaust manifold or catalytic converter that is releasing fumes to the engine compartment which makes it's way into your "fresh air" intake for your climate control.

Find that leak for your own safety

I smell exhaust fumes in the cabin. What could be causing this?

The most common cause is an exhaust leak in the engine compartment near the engine. The exhaust fumes are pulled into the passenger compartment thru the heater vents. Switching to Rec might cut off the intake of air from outside.

I have a 2010 Chevy Equinox. The air vents in the vehicle all work except for the drivers side right vent ( to the left of the radio and to the right of the driver ). All vents were working but it seems as...

The exhaust inside the car would suggest the vents in question have fallen apart somewhere in the dash between the engine compartment and the interior allowing fumes to enter the cabin. Get that checked at a garage right away. Very dangerous to breath exhaust fumes.

2004 VW Golf, smelling fumes. The fumes come from the vents. The smell is NOT there when I have the heat, AC or circulation on. I'm confused because I do not hear anything different and would assume it...

I emphasize with you on this problem. If you are smelling fumes you are inhaling car "exhaust" which is extremely dangerous as you know. I have a 1999 Passat that had a "fume" issue that baffled me for over a year. Your description of the conditions that you smell the fumes may not be complete enough for me to definitively say what your problem is but I will tell you what I experienced and discovered on my car. I only smelled the fumes when my heat or AC was on and the car was NOT moving forward. Also, if the AC recirculate button was on I didn't smell the problem as bad. So, what I found was that the car's emission control piping was leaking the exhaust fumes that bypass the pistons and go into the crankcase. These fumes are normally piped back into the intake manifold to be re-burned to reduce emissions. With a completed disintegrated rubber emissions pipe coming off the engine block, the fumes entered into the engine compartment which is sealed from the interior of the car. So, how did the fumes get in my car? Well, when waiting at a red light and with the heat or AC on (no recirculate) the fumes would fill the engine compartment and overflow out the wheel wells and wrap over the hood to the intake vents (near the wiper blades) of the car's interior air system. If the recirculate button is pressed with the AC on, the car's interior air (no exterior air) is recirculated inside the car to cool it faster and I didn't smell the fumes as bad. Also on windy days the fumes didn't get a chance to wrap over the hood and get into the intake vents. Because of the unique conditions that had to occur in order to smell or not smell the fumes it was a difficult problem to solve. By the way, the disintegrated rubber pipe was almost impossible to see and there is no real reference material to read that describes the location and depiction of the emissions plumbing. I hope this helps you!

Fumes in 2000 Toyota Sienna

On the dash there is a switch/lever that allows you to select fresh outside air or recirculate the air in the cab. Any smell may be coming in the freash air position which would allow smelly air from the engine to come into the car. Check for broken flexible exhaust piece or leaking gaskets around the cat converter to start with or a hole in the exhaust pipe inself

Engine light is on autozone evaluation says where is this found and can it be fixed at home?vent valve sylinoid curcuit

Yes you have vent valve and a purge valve its part of what is called your EVAP system. what it dos;e is simply tranfure gas fumes that come from the gas tank and then are stored in a charcoal canster.The vent valve opens and close;sto allow gas fumes to go to the canster then the purge valve also opens and cloese;s to let the fumes from the canster go into the engine to be burned The vent valve is around the gas tank and charcoal canster and the purge vavle it on the intake manifold Iwould check bolth it could be there clogged or stuck But there not that expensive and not hard to replace
