2006 Chrysler 300 Q&A
2006 Chrysler 300 Question: Why does heat stay on even when thermostat turned to cold (AC off).
About a month ago I started to hear a clicking sound from under the dash when turning on the AC. I had to play with the zone, fan speed, etc to get it to stop. Now the clicking sound is gone but the heat never goes off unless I turn the AC on. With no AC on and the thermostat turned completely to blue the heat still comes out. - Fixsqueak77
You have a bad blend door actuator. It also could be a bad climate control head. - PARTS GUY
blend door actuator went bad thats what the clicking noise was - globalhelper
