    yep you were exactly right! stupid Heater core went out the next day after you posted urs. so we bypassed the H-core just so i could drive it - now we're having O-heating problems! added coolant, but still reads 230 although engine is cool to touch. We're currently trying to burp the system but its very slow going and doesnt seem to work. Y didnt VW put a stem valve or somn in the hose for this? This sucks! Dunno if the T-stat or W-pump, or both is bad. any thoughts?

Bad heater core. What is happening is when you turn on the air you are getting fumes from the heat of the engine and the heater core leaking causing you to get a smell and also fumes. I would suggest that you take it to the dealership or a mechanic and have the problem fixed ASAP due to the health issue

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

Strong gas fumes outside of car


Possibly the vent line that routs fuel vapors from the gas tank to the charcoal canister has come loose. Check the hoses and lines around the fuel tank for leaks. There will be a fuel feed line to engine, a fuel return line from engine, and the evap. line or hose that carries the fuel vapors.

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!

Truck is blowing vapors out of heating vents...fogs inside of truck


This is usually a sign of a heater core that has a leak. check for low coolant level in your radiator. there is a condensate drain for the blower box, see if coolant is dripping from the drain under the truck. To make a temporary repair, after confirming leaking heater core, loop one of the heater core hoses back to the engine, bypassing the heater core. I say after confirming because the heater core hose nipples break easily when removing hoses. The smell in the cab would be a sweet smell from leaking coolant.

On a very humid day fog can be seen coming out of vents when using the AC. This would be a normal condition.

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.

Coolant vapors coming through vents


Sounds to me like a leaking heater core, probably just started. Quite an extensive operation to replace. If you happen to be in a cold climate, the windows will undoubtedly fog up. Hope this helps
