Get the sales manager and the service manager by the balz! Let them know how PO'd you are that someone from the dealership you once trusted to work on your vehicle has let you down. You have asthma! The odor of ignorance and disrespect of this misshap. sent your lungs into an aggrevated hell!!!!!
I cannot believe that you grabbed your inhaler while driving and almost ran over some old lady in a wheelchair.
I would let them know how your trust and expectations of their dealer service has gone to $hit at least.
Do make them clean out your whole AC system!!!!!! Steam clean the entire vehicle... esp. the headliner and under the seats. if you have leather... forget it.. every time that truck heats up inside, your going to smell smoke!
Good luck! I'm pi$$ed off just thinking about it!
