Freon smell coming through vents on 323ibmw

I don't think there is any smell put into refrigerant,so
you may be smelling coolant from a heater hose or
heater core leak or system valve, somewhere

The A/C cycling could be low refrigerant, in which case
you have it leak tested & system repaired

You don't try to add yourself,it will leak out & pollute
the atmosphere

My 2004 pontiac grand am had acheck evaporate code 0442 . I tried the first easiest part and also mine was very worn out was the fuel cap. I replaced the fuel cap with a new one. Check engine light had...

OK, P0442 is an evaporative leak fault. The gas cap may well have corrected that issue. If you smell gas from the engine area you almost certainly have a fuel leak. You should be very careful - you don't want your car to catch fire and put people's lives in danger. When a car catches fire it goes up very quickly, and if it's near your home....

Look by the fuel injectors and fuel rail for signs of a leak. If you don't see anything there have a professional technician look at it.

When my intrepid is on and running it starts smelling gas from the engine to the inside of my car what could it be

Hello, This could be dangerous to you and your family here. There could be a number of reason it sell like fuel in the car/truck. All vehicles are a close operating system on the fuel circuit, that means no leaks or leaky fumes of fuel.

Don't drive it. Get into a certified shop to get this condition taken care of now.. If there are excessive amounts of fuel fumes in the vehicle it can and will create a condition it will flash over. Burning everything inside of your vehicle. Which includes you and your family. Don't mess with it.

These fuel injected cars/trucks have high pressure on the fuel system and it could have a leak from the fuel tank all way to fuel manifold rail which set on top of the fuel injectors in the engine.

Please, for your safety, get it check out. GB you...stewbison

Gas leaks are serious. If it was in the evap system the engine light would be on. So you need to check or have checked the entire system. From the top of the fuel tank, the lines under the vehicle up to the engine(mostly steel) At the engine they turn to rubber or hard plastic. Also check the fuekl rail and injectors. There are two Orings per injector. And check the fuel regulator. I lost my van to a gas leak that ignited from a faulty spark plug wire.

When you turn on the A/c you'll smell fuel. I think i need to regulate the fuel control cause there is no leaking in the car.can i know more about fuel injection in this car ?

don't know for sure but a lot of the gm cars have the fuel lines running though the firewall so it would be under the dash and could be leaking.
I would ask the dealer about this problem.
could be a hazzard in the making.

Check your fuel regulator.Pull the vacuum hose off the regulator and look for fuel inside hose.If you see fuel inside the vacuum hose replace regulator.
