Can not find any leaks and car temp stays normal at all times. Heater fans blows cool to warm air out of heater vents and defroster. Will get a little warmer as car is driven or moving. All heater controls seem to be opening and closing as they should be. No leaks or small in side or out when car is in use. Does anyone have any ideas where to start to check for the problem.
