AC poblems continue with the 80q

[Tom Love]

I had to disconnect the power to the compressor because the clutch would keep cycling even though the ac switch was in the off position. No cold air but it just kept engaging for 2 seconds then popping back out then cycling again every 5 seconds. Turn the switch on and the radiator fan would kick on and I would get some cooler air out of the vents but the compressor would still cycle at 2 seconds on and 5 seconds off. What would make this thing run with the ac switch turned off?
The ac guys tell me they charged it (127.00 later)
Thanks again for the help received and for any further input.
