Problem with the heater. No heat in my jeep!

Hi guys, I'm new in here and I have some problem to share for my Jeep Wrangler Sahara year 2000 inline engine 4.0L.
I'm trying to turn the heat in the car and I'm getting nothing but a cold air. Also the antifreeze is being consumed . I'm checking underneath the car for any leaks, but there's nothing . Guys, I need help to find what's the problem. I'm driving cold in my jeep!

Most frequent cure is to flush out the heater core.
Unhook hoses from engine (pass. side of block) and mount a garden hose, back and forth, on each one, flushing core in both directions.
Do this severl times and see what happens.

That fixed 90% of the no/low heat problems.

Consumed antifreeze is not good....unless it's just a leak in the overflow bottle. Let the bottle run down and see if it keeps disappearing in the radiator. If so, most often a head gasket problem....if no external leaks!

Good Luck
