Air Conditioner Compressor Question

[turismo177]

I just spend $70 to have a repair shop look at my AC and another $50 for R134 oil. The air is still not blowing cold air. When I opened the hood and turned the AC to max cold, the clutch at the very front of the compressor is not turning. Shouldn't this be engaged and spinning when the AC is on?

I would appreciate any advice you can give me on why this may not be turning. As a side note I noticed I have a wiring harness coming from under the breather element. This harness has 3 plugs on it and two of them are plugged into the AIR compressor and the other one (the shorter of the three is not plugged into anything). Based on the length it looks like it would plug somewhere on the back of the AC compressor but I don't see a male end to plug it to. Note: There is a plug in on top of the compressor (just behind the clutch) plugged into the AC.

Thanks in advance everyone.

Thanks for the help Junkie. I had a loose connection and now it is blowing 60 degrees at the vent. Much better.
