When I drive my 94 Pontiac GrandAM with the AC on, it runs fine and
the AC air smells good. But after about 30 minutes driving with the AC
on, the AC air starts to smell like petrol. I tried to leave the rear
window open a bit (like maybe it has to do with cabin pressure) to no
avail. Actually, I'm not sure if it's petrol or oil that I'm smelling,
but I don't want to take chances. But it's definitely
hydrocarbon-based (but not burnt-oil-like).
I can bring it to my mechanic, but he'll have to drive it for half an
hour before the smell appears. Anyone have a clue why this is
happening? I can imagine a fuel leak or exhaust leak, but WHY is it
appearing only AFTER 30 minutes later?
Summer's gonna be a scorcher. Help!
