Q: Broken heater

asked by on November 13, 2016

When running my heat it comes out cool/Luke warm. My coolant levels are where they should be and I've even tried to release air pockets within the system nothing is working. My car gets to operating temperature just fine and both the in and out hose on the heater core get hot. I've considered a flush but since both hoses are warm I assumed there wasn't any blockage. Any advice? SOS it's getting cold outside

My car has 140000 miles.
My car has an automatic transmission.
