On my 96 civic heat only blows throught the vent when you push the button for defrost or ac or whatever it does nothing just keeps blowing out the vent. Just wondering what all it could be I know the climate control switch could be bad i guess any other ideas?

 

somebody must know something.

 

r u sayin it only comes out the defrost not on the floor nor the vents on the dash?

 

only the vents when I push a different button nothing happens the light comes on but thats it.

 

Sounds like the mode door is just stuck. Normally if something breaks it would just go to defrost since that is the default.

 

where is that at?

 

Behind your dash, around the blower fan. It could just be behind the glove box but really I have no clue on your car. You will need a service manual for your car to know what to test.
