If by cycling you mean turning off and coming back on again (sorry, I'm not too good with technical details) then I honsetly don't recall if it was doing this or not. All I remember is that when I bought the car, I was told the A/C needed to be charged up. I got it home and it was blowing cool air, but not cold. I bough a recharge kit from a local store (the same kit I have used several times before, all with complete success), charged the system up and now I have no cold air. As for now, I have never owned a 3800 II engine so I don't know how to tell yet if the A/C compressor is on, but I don't recall hearing any noise difference between when I have it on max-heat and max-air, which is why I thought that maybe the climate unit itself was bad.
Sorry for the terrible explaniation, but as you can tell, I am not too good with technical stuff.

Follow the A/C lines down to the compressor. With the car running and A/C on max, see if you can hear a click and watch the outside part (only real visable part) start spining, and then click again a few moments later and stop.
Also, for what its worth, I had to replace my outside temp sending unit last week due to high temp redings, The dealer sells them new for about 15 dolalrs/

I did as you said but did not hear any noise from the compressor nor did I see anything spinning. Any other idea'*?
Thanks again for all your help, guys.

I don't know if my post got through to anyone as I can not see it myself so I am writnig it again. You said to follow the A/C lines down to the compressor and look for movement and see if I hear anything. I did that and didn't see anything moving and didn't hear anything either. Where should I go from here? Any idea'*?

Interesting. Sounds like you looked at the compressor and didn't see the clutch engaging and disengaging as the compressor should cycle on and off.
When you turn on the a/c do you notice the engine rpm increasing and decreasing? As my compressor kicks on and off the engine is put under a load and should increase rpm by 2-500 to compensate.

I have not noticed any change in RPM when the A/C is on, but I will check it when I go out to the car. I have the auto climate control, could that be causing all of this? It seems that when I set it on Max-cold, it doesn't realize that I have set it at that, and it keeps blowing out hot air.

I was playing around with the A/C again today and noticed that the RPM'* do change a tiny bit when the A/C is turned on. When I first turn the A/C on the RPM'* drop 100 or so. Any help there?
