Hi. I have a 2008 Chrysler Sebring Convertible.
Trying to find out why there is barely any hot air blowing through the vents. The air blows strong from the vents but doesn't get hot. It's just blowing warm air.

 

Check coolant level.
What does the temperature gauge on the dash read?
Feel the heater hoses leading from the engine to the firewall. Are they warm? Hot? Cold? Are they both the same temperature?
Your heater core could be plugged.
A hose could be plugged.
There could be air in the system.

 

Coolant level is good. Temp gauge is hair under half way. Never goes higher. Haven't done anything to the system to get air in there.
Is there anyway the **** that rotates from cold to hot could be bad? I noticed that when I switch the fan to recycle air, the little air conditioner light that's on the **** comes on. If I push the ****, the light goes out.
When The **** is rotated to the cold side, the air cond works fine.

 

There are lots of ways the **** can "go bad". That **** sends a signal to the body computer which in turn sends a signal to a "blend door" in the plenum under the dash to mix warm and cool air to control the temperature. Things that can "go bad" are the ****, the connection to the computer, the computer, the connection to the blend door, the motor that moves the blend door or the door itself.
It could just be a calibration problem. Visit this site and ask the guy who runs the site about a calibration procedure for your model and year: Chrysler, Plymouth, and Dodge climate control computer fault codes
If that doesn't work, you may need to visit the dealer for some professional assistance.

Rule out things like a plugged heater core or blocked hose first.
