Why with the heater on does the Chevy Impala blow cold air thru the driver side vent while hot air blows thru the passenger side vent?

you probably have a faulty drivers side temp door actuator
OR
The problem you have is the GM heater control unit has lost it's calibration, which can happen from time to time. The way to reset it is, start your car and turn your heater off, and shut off the car, pull out the keys. Then with vehicle off, disconnect the battery, (or batteries if two). Let sit for 10 minutes, then re-connect battery. Get in and start the engine, DON'T touch anything, let the heater control unit re-calibrate for at least 40 seconds, (by the clock), then try turning on the heater. Usually problem over, ! Note: make sure the radio is turned off before disconnecting the battery and if this does not solve the problem, chances are that the vent accumulator has gone bad. It's common for the gears in the accumulator to crack and seized, if your luck it's just to reset or just to lubricate the gears. Good luck Let sit for 10 minutes, then re-connect battery.
