Nissan Repair: ac heat, short answer

Question
hi i have a problem with my ac -and heat it wont work but the defrost will what do you think i should do

Answer
Hi Ryan -

Need to know the year, make and model of your car.

The short answer - Usually this means there is a vaccuum hose off, or the A/C duct door is stuck behind the dash. That is usually run by vaccuum depending on what year vehicle you have.

Does the A/C work OK, or is it just the heater that is not working. Not blowing air thourhg the vents?

Please clarify -
