Having problems with your 2000 Chevrolet Blazer ?
My heater wont get warm? The temp gauge gets up to around 180 degrees. What should i check first?
There are two rubber hoses, about has big around as a thumb, going into the firewall just above where the front passenger's feet would be. First thing I would check is to see that both are warm after the car warms up. These are the coolant supply and return lines for your heater core. If it is plugged, one will be warm and the other cool. Generally interior heating problem where the engine is otherwise normal will be a heater core issue.
