On start up the engine leaked some fumes that I think were coming from the AC. Prior to this I had the AC on and I think I left it on and then started up the engine. I saw some fumes come from the passenger side, what could have been the cause of this?
one possible reason could be your heater core has a leak please explain what these fumes smell like as it could be numerous things like a/c condensation tray drain is clogged so the smell is it sweet,musty,burning etc and you said you saw fumes ?? what do you mean smoke etc?? exterior or interior ?
