My 2001 GMC Jimmy blows hot air then cold. I have to keep adding antifreeze, but I can not see where I am loosing it. The passenger side floor is not wet, and there has been no antifreeze on the ground under my car.

the small radiator just inside the cab, where the hoses go to the heater is leaking. You may try using stop leak (many don't recommend this) or take off the heater radiator. it will probably get worse when you turn on the heater and fog up the windshield if not fixed. hope this helps.

Disconnect the heater hoses from the water pump and the intake manifold. Get a compressor and blow out the hose (put the air hose into the the hose that came off the mainfold. then flush the system and replace the antifreeze.

sorry not an easy fix, you must replace the freze out plug by taking out the old one and replace with a new one. needs to be done on a lift not a backyard job
