Well, here's my first post, after my introduction at the welcome area. I hope someone can help me out.

I own a H-1 Van, it has double A/C, one in the front and one in the back, everything works fine, except that when you put hot air. It continues to blow, but no hot air, not even warm air. I've checked the hoses in the engine, everything seems to be fine. All the hoses are there. How does the system in this Van, is it mechanically or electrically controlled. Perhaps all the hoses are full of air, how can I bleed it? All the info would be gratly appreciated.
