Question
my car has no heat though the vents but the defrost does work. it work the first night but when i drove it the next day it wouldnt work the blower moter still kicks on. what can i do to fix it?

Answer
Has there been ANY work of any kind performed in the engine compartment or on the inside of the vehicle.

If NOT, This sounds like a vacuum problem whereas you have a broken vacuum line and the AC/heater programmer is not getting any vacuum.

This will require more pictures than this website which is not mine allows. Therefore, E-mail: onlineautohelp@msn.com
