All,
I have a 98 GMC Jimmy with 75K miles. This is the second winter in which I don't have heat. With the heater on and no fan, I can feel hot air. When the fan is turned on, the air is cool. Last year I pumped water into the heater core and the heat was very hot. I don't think I am getting the flow to the core. All summer the truck ran fine and ran a normal temp. I saw a few articles in the past about bleeding the system. Does anyone have any ideas or suggestions?
Thanks in advance,
