So I noticed about last week that the only
way I had heat in my 2001 Dodge Intrepid is
if I hope the idle at 2000 RPM now it doesn't
seem to matter where I hold the title at I
have no heat any ideas on what is wrong I
think it's the heater core but don't want to
tear into it tell I know
First check the coolant level when it is cold, refil if needed, if that is not it then it is possible you have an air pocket in the heater lines and or the core, then get the vehicle up to operational temp and check the heater hoses they both should be hot to the touch, if one is hot and the other just warm then the flow is restricted through the core. Another thing to check is how fast the cooling system makes pressure when first started, if it makes pressure within the first 2 minutes then it is likely that you have blown head gaskets, a block check will confirm or deny this.
Just to add to what Tennisshoes said,all so check your thermostat.
