The a/c compressor will not turn off, here is what I have done so far:

I unplugged the green wire going to the compressor and it turns off

Plugged green wire back in and unplugged a/c relay and compressor is still on!! I know what you are thinking-must have the wrong relay?-however the relay I unplugged has wires going into it from both the blower motor switch and the a/c switch on the dash so it's gotta be the one.

I then unplugged wires from a/c toggle switch on dash as well as unplugging the connector from the back of the blower motor switch, fuse #12 and brown connecter under hood behind receiver/drier unit and compressor is still humming away!

If I unplug the connector from the high pressure switch on top of the receiver/drier then the compressor turns OFF.........

What next

Thanks
