i have a 2004 pacifica. i changed thermostat, checked heater actuators, flushed heater core. both hoses to core are warm still have cold air blowing out. im considering changing climate controls. any suggestion before i invest in climate control.

 

Hoses going to heater core needs to be as hot as your upper radiator hose if they are not you have a clogged heater core.

 

I have a little heat coming out of blowers that is low but if turned up gets cold.
