Check to make sure you fan is working it is usuallt either on the firewall on the passanger side under the hood. it will have a cover over it with a hose going in it. if that is not kicking on than you need to replace the fan.

Defrost blows constantly? How do i fix it?


does it blow through the defrost vent only when you switch to vent/floor or does it blow through defrost and vent/floor? is it a switch that is just electric or a manual lever that you slide? the manual type will have that problem if the diverter or the linkage behind the lever(in the dash behind the panel......may be able to access underneath) becomes broken or disconnected so that the air is diverted to defrost regardless where you move it.if you can get to it, you will see what is broken or maybe a fastenerr fell off.
