Question about 2003 Honda Accord 2.4 LX
2003 Honda accord 2.4l, Wife was driving and car had no heat at all. She took a photo of the heat gauge for me and it was very close to the hot mark and has never pasted the half way mark before. So far have replaced the thermostat, water pump, and flushed the heater core which was not full of debris and has great flow. But now the car has no heat at idle and lots of heat while driving. I have done a full bleed of the cooling system as well. Very confused at this point and frustrated. What could be the problem??
Your heater core is partially blocked. I know you flushed it, but you can't get all of the sediment out and make it flow under low RPM because of the blockage caused by scale and oxidation caused by minerals in water/coolant. Try to flush it again using CLR, and if that doesn't work, you'll most likely have to replace it. Hope this helped!
