Your vent relay switch is bad and you will need to replace it. It is located underneath and behind the glove box.

Heat and AC vent problem.


most likley you have a vaccume leak somewhere but also the linkage to the door that that directs the air flow may be in a bind. another possability is the hvac controlls. hope this helps

No heat, when I turn on heater- all cold air flows out


sounds like you have a stuck blend door in the HVAC system. If its not controled by vacuum the servo motor is bad or the vacuum line is bad. This door moves back and forth to go from vent to floor to defrost. and you have one to go from cold side to hot side. Hope this helps you
