i have an 89gt and i put a new heater core in awhile back and a vaccum line on the dial came off. its the one that controls the vent, ac, defrost. there is a yellow vac line that came off. it is only blowing out of the defrost, even the ac blows from the defrost. does anyone know where this yellow vac line goes? thanks

ALMOST STOCK

Try laying your head on the gas pedal and look back at the dash, you'll see a gold looking cannister that's where the end of the yellow line goes to.
