Hi,
You should be able to do this on your own. What I suspect has happened is the air mix damper cable has either come disconnected, damaged, or something it attaches to (controller or damper lever) has broken.
Do me a favor. I attached a pic below. That is the HVAC box/heater control unit. I highlighted the cable and lever related to the air temperature entering the vehicle. Locate this part and adjust the temperature switch from cold to warm a few times to see if that lever is moving.
Let me know what you find.
Note: I am basing this on a Sebring Coup because the sedan didn't show a V6. If I am incorrect, let me know.
Take care,
Joe
