Heater full blast but no hot air?
Hi I have Opel Corsa utility 2007 model my problem is the heater is not working,I replaced the thermostat and the water pipes leading into the cabin are hot but the air is cold.I also notice the temperature gauge is always on cold most of the time.
Change your thermostat. It is stuck open and the radiator fluid is never getting hot. It's just circulating around in a constant circle.
