the heater blows heat from the passenger side only there is pleny of air on the drivers side but the air is cold. Also the defrost is only hot half way and the other half is cold.

 

not sure i understand.

1. when you have the heat on (what setting?) it only blows hot air on the pass. right? when this happens the air comming from the drivers side is cold? like a/c cold or not hot?

2. all newer cars have the a/c and defrost running at the same time. it helps to defrost the windshield faster. what half of the defrost is hot/cold?

3. helps to know what year, model (2-4dr), and eng you have. write back.
