heater blowing cold air
I just finished replacing the heads on my 2000 4,0 explorer, flushed the system with a radiator flush, refilled with 50/50 prestone and now it blows cold air. Both heater hoses feel hot to the touch. Is there a fuse or something I might have blown? The blower motor works fine. Any advice greatly appreciated.

could be blend door, but seem like a real concidence since yo were just working on the radiator.... park the truck on an inclilne, nose up so the radiator is at the top of the hill. remove the cap and filll it up, let it idle and get all the air out. when you think its full, drive a few miles down the road and let it set overnight to cool, then check the radiator and fill tank again.
