I installed 2 new thermostats on 2010 Dodge caliber engine run cold and no heat what should i do next

 

Welcome to the forum.

Does the temp gauge rise as it should?

 

No it gose less then half way. i also flushed the heater core. they should have never put 2 thermostats in that engine.

 

Ours runs a little under the 1/2 under half way when up to temp. I am wondering if you actually have a blend door problem in the dash as to why you are getting no heat. In 2010, they switched from the tried and true cable actuated to electric actuators that tend to break from time to time.
Is the top heater hose hot after it gets up to temp on the gauge?
