After filling my radiator I cranked the engine and let it run to operating temp so I could check the heater. I have read about the trapped air issue and wanted to make sure I didnt have it. When I turned the heater on I got cool air from the dash vents. But I swapped to floor and defrost and it was hot. The ac slider was off and there is no freon in the system yet. Could it be a vacuum problem making the dash vents not properly swap to heat? How could hot air come from the other positions but not the dash? Cdover73
S83's only blows heat on window and bottom floor. Will not blow heat out dash vents. Why? Cant tell you but it is what it is.
Well I wont argue with that! At least nothings wrong with it. On the plus side I got the ac blowing ice cold...
