Heater blows cold air, there's no anitfreeze leaking into truck. Just wanted to check the fuses to see if there is a related fuse that might need replacing. Can't think of anything else short of taking it in to a mechanic. Pulled off fusebox cover but don't have an owner's manual that shows the configuration. Does anyone know if there is a fuse for the heating system and where it's located and the fuse rating? Thanks! Steve

P.S. Here's an idea. Start the truck up and let it run for a while. Is the temperature gauge the normal area? Also, feel the radiator hoses. They should be hot. If they are cold or barely warm then it could be a thermostat that is stuck open. Good luck!
