Does anyone know why my heat only works on my passenger side and not my driver side. it blows cold air out my driver side and hot air out my passenger side.

 

if you have the dual controlls on the car take it to the dealer you might have a fualty switch so it is not regestering the movement of the ****. sounds crazy but try pushing it down see if it was instaled upside downb on one side. Those have a ele. switch in them the causes it to heat or cool not the old cabel styles.

Also if you get adventrus pull the dash apart and see if you have good connections on all of them in the bcak of that pannel.

other wise you might have a vent that is sticking under your dash or a vac. leak ifg you dont have warrenty you can stick you head under there and see if you can hear it or find it.
