SOURCE: gas smell
I would check to see if you have any leaks also. But what is more important is, is this happening when the vents are on recycle air or just when you have them on fresh air. If its when the vents are on recyle air. You not only have a leak, but the gas is getting in the cab of the car as well. This is a very serious problem.
start by going to a news paper company, and get a big roal of printing paper. They give this away when the roal is almost used up. It is white and durable. Put the paper under your car and secure it with rocks or something. Run the car until the problem starts to happen. Now let it idle for a few minutes, and start looking on the paper to see if you get any gas drops. Make sure the hood of the car is closed, so it doesn't evaporate before it falls to the ground. If after a few times you still cant find the problem. Meticulously go over every inch of your fule lines. especialy around the filter. The plastic clips are very easy to break with some age. Hey guess what this could be a great time to REPLACE your fuel filter. follow the lines especialy around the top of the engine where there are a lot of rubber lines and plastic connections, that can be disolved after years of use, or days of using fuel with fingernail cleaner. DONT USE FINGERNAIL CLEANER IN YOUR CAR. THIS IS A URBAN LEGEND, AND HAS KILLED MANY CARS.. let me know what you find and how this goes.

SOURCE: Car Heater smells strange
from he Popular Mechanics site if the smell in your car is like maple syrup:
(1) SMELLS LIKE: MAPLE SYRUP
WHEN: After the engine has warmed or possibly even after it's shut off for a few minutes.
THE CULPRIT: Coolant containing sweet-smelling (but toxic) ethylene glycol is leaking from somewhere. It could be coming from a radiator or heater hose, a failed intake manifold gasket or cylinder head. It might be coming from a leaky radiator cap or the radiator itself, especially if you smell it outside the car. A strong odor inside the passenger compartment probably means a bad heater core.

Usually a smell of antifreeze in the cab when the heater is running is a sign the heater core is leaking. Just becasue you dont see a leak at this time doesn't mean there isn't one. It might small enough that the haet from the core is burning off the leaking antifreeze. I would suggest replacing the core before you get in one day and there is a puddle on your floorboard. Or if you go to a local parts store and rent a cooling system pressure tester, wait until the vehicle is cold, pressure the system to 12 lbs and then check for leaks. Hope this helps you out......

Testimonial: "that is what i also thought, no puddle yet, just waiting. I tried a sealant for now, but will get a heater core"
Hey man odds are you have a small fuel leak under the hood probably like a pinhole in a fuel line. When you turn on the ac you are pulling air from the front of the vehicle in turn pulling in the fuel smell. Find and stop the leak and that should get rid of the smell in the cab when the ac is running.
