I have a 2007 chevy Impala. I get heat on driver's side of the car, but only cold

defrosters.

Dual control HVAC systems are notorious for broken blend doors and or servo motor failures, so that is your air problem, a HVAC code scan will tell the tale. Now if it’s steam on the windows and you get a slight sweet smell it is usually a leaking heater core. But if it is just moisture then the AC drain hose is most likely plugged. It’s under the car on the passenger side about midway up the bulkhead.
