Did you disconnect the electrical connector from the A/C compressor?

i have to test it tomorrow, I haven't had the daylight as my wife uses the car during the day and doesn't get home till very late. I bought a new ignition switch just in case, though

My initial thought was that it is somehow associated with the cooling fan(*). I was keeping quiet though as everybody was running with A/C compressor, and wasn't sure what to expect. That would explain why you have to run it around the block after running the A/C, the cooling fans remain on for a minute or two after the A/C is shut off. I was also not sure as there was never any other times it was staying on. It would probably be a good idea to confirm if it is related with the fan running.
Now, if it is connected to the fan running, I have no idea where to even start from there.
I am not sure how this could happen, as the way the PCM controls the fans, is by grounding the negative on the trigger for the relay. The entire system is usually live when the ignition is on anyway.

to me it seems like the ign switch was marginal before and after it heated up from the extra load it needed time to cool down, the load could have been anything but the a/c is the biggest load in the car most times. i think now it went all the way

Order a new a/c clutch electrical connector WITH the diode in it.
