Chrysler LHS: Fans and AC don´t work

Yesterday I just bought a Chrysler LHS 1995. It's awsome ride and the interior is crazy.

I started to overheat when I was parked with engine running (waiting for my friend) and a white steam came from the engine.

Both fans are not working and the seller told me that day before yesterday he noticed the AC stoped blowing hot air.

I also noticed today that the smaller fan belt (the left one connecting AC, CS) is missing. I was told by one engineer that that's not the problem so buying that belt won't make the fans to run.

Any advice or ideas?
