2004 Chrysler Concorde Q&A

2004 Chrysler Concorde Question: Why don't I get Hot air out of the Vents?

I can turn the temp dial all the way to hot and the air is still cold. The return heater hose seems cooler than the other @ the firewall. How can I test the temp dial switch or the valve that controls coolant flow through the heater core. -
Answer 1
I would start by checking the blend door operation -
