2003 Dodge Grand Caravan Q&A
2003 Dodge Grand Caravan Question: I am not getting any hot air. The blower motor is working perfectly.
Are both of the hoses to the heater core too hot to hold onto with the engine running and at full temperature? If not you might have an air pocket in the heater core or it may need flushed out or replaced. - cardocIII
