AC smells like gas

[Mephisto]

kicked on the AC while i was on the freeway today, and after about 5 minutes i started smelling gas, so i turned it off, and the gas smell went away. turned on the AC about 10 minutes later, and sure enough it smelled like gas... anyone ever heard of this? or know what a cause could be? it doesnt smell like gas when i use the heater. or the regular air vent, just when i use the AC

I'm guessing you have a fuel leak under the hood. Check to make sure the hose to the carbon canister is connected.
