My A/C and heater only blow out top window vent.How do i fix. I am assuming its some kind of problem with the ducts but want to know for sure before i go to take dash and **** out to fix

 

what year is it

 

89

 

u have a vacuum problem. the heater control uses vacuums to change the vent location. check the vacuums

 

is it something i can fix or will i have to replace the vacuum

 

he means check the vacuum connections and the lines. and they are not hard to replace.

 

cool cuz i would like to fix it already. Since it just comes out the one vent i let run up the windshield and then put my visor down at angle so its goes off that and blows in my face. Works for now but is getting kind of old
