I suspect that the clutch was the original problem. Clutch slippage is more common than one might think. Checking the air gap is very easy and quick to do.
When the air gap gets on the outer edge of the specs it can randomly engage or disengage without any warning or reason.
Often engaging initially when engine is cold then drive a couple of miles and no more cool air when the gap is just past specs. Reving the engine doesn't reengage, going faster doesn't help but often you can "bump" the center of the pulley and you now get cold air until the electric to the clutch is removed and you have to bump it again.
Have ran into that myself with a '03 Ford..
OP most likely added a new problem by adding refrigerant when it wasn't really needed (to much air gap mimics the same symptom as too low on refrigerant)which leads to overfilling.
