I have a 2004 Chevy Impala 62K miles with the same issues and I took my vehicle to the Dealership as I'm not a mechanic and they deteremined it was the temp actuator on the 04 model there are 3 as I was getting warm air on the passenger side;however it just blew cold air on the driver's side. I ended up paying $301.72 just to have this plastic piece replaced. The price on the part alone was $54.88 the labor $213.95.
Good luck, I'm now having other issues with my battery light and a few months ago I just replaced the battery, alternator and at 32K miles the waterpump also went out? I'm not happy with this vehicle.
