hot air on one side only when heat is on
Sounds like a broken blend door or recirculation door. You will have to have a mechanic check into this. Something is blocking the driver's side from receiving hot air.
Not sure,cause one day it's hot on the passenger side, then 2 days later it's hot on the drivers side. At the same time the cold air is switching as well. 2013 Impala Ltz
