The system blows cold air when rpm's are below 2500-3000. Have already replaced water pump and thermostat. Still no heat at idle speed. Any idea's what else it could be

Do you
have the same problem?

EVERYTHING WORKS PERFECT EXCEPT AT IDLE NO HEAT. HIGHWAY SPEEDS HAVE HEAT. IF YOU FOUND FIX IT WOULD HELP ME OUT GREATLY.

THANKS
