Dodge Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.The problem you are describing is very likely as you have been told. The heater core is a very common cause on the Nitro and it is a big job, the heater plenum will need to come out and to do this you will need to remove the instrument panel. Before you consider doing this try placing your hands on the heater hoses at the firewall with a warmed up engine and check and see if both hose are getting nice an hot as they should be.
