In response to YOUR remarks -
re 2) Yes, when my wire is plugged in the clutch engages and disengages every 30 seconds - couple minutes. On/off, On/off, On/off....
re 3) I have lots of mechanical know how, especially with engines and transmissions, and most other car related stuff. Can I change the switch with the compressor where its at? Or do I need to remove my belt, unhook the refrigerant lines, THEN remove the compressor so I can change the switch?
Another question for you-
How do you test the parts to know if it's the clutch, or the switch that needs replaced?
thanks again,

If the compressor is cycling frequently its overfilled, or clutch is bad. I would hook up some guages and check the refrigerant level. Sometimes a switch "can" cause it.
To change the switch is easy, no unhooking lines or anything just the switch will come out.
To test the switch is very easy, take a jumper wire and run it to the plug that plugs into the switch (directly from side to side on the plug) Turn a/c on and see if it stays engaged. If it still cycles you know the switch is good and the problem lies with the clutch or compressor. But if the compressor stays on the whole time its jumped the switch is faulty.
Hope this helps.
