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.

Speaking of this,, What does it mean ( if anything) when the compressor is doing the clicking and start/stop cycle very quickly? My AC works great as far as I can tell ( 94 SSE ) Sometimes mine does this like every 5 or so seconds. Not often, but now and then.

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.

Orbitz, do the aluminum AC lines under the hood get cold or wet after the AC has been on for a few minutes? You DO have it on AUTO, right?

Hey again. No the A/C lines do not get wet or cold at all. And yes I have it on Auto.

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?
