Sounds like you have a manual HVAC system. If so,, theres a resistor board in the HVAC Air Box that has blown resistors. It look like this:



It lives in this hole on the bottom of the Air BOX:



This is what it will look like when you see it installed:



Hope this helps.

If you have a Dual zone,, the controlle looks simular BUT,,,,,, its WAY more expensive:



NOTE!!! You do NOT need to completly remove the rear screws. The plate in the controller is slotted.
