WHERE IS THE AIR CONDITIONING UNIT? UNDER DASHBOARD OR IN DASHBOARD

MY TRAILBLAZER IS MAKING NOISE FROM THE AIR CONDITIONER. SOMETIMES IT DOESN'T BLOW AIR OUT OF THE FRONT VENTS, BUT I CAN HEAR IT BLOWING SOMEWHERE. NOW WHEN I START THE CAR IT NOCKS ABOUT 3 OR 4 TIMES AND THEN TICKS FOR AWHILE, THEN IT STOPS.

The AC Compressor is located in the engine compartment, it is a belt-driven accessory.  It sounds like you may have a blower motor problem, or a problem with the blend door.  Have this checked by a mechanic as there is a lot of disassembly involved in this repair.
