I would also peel back the split loom from the wiring on the high pressure switch to check the integrity of the wires. Mine has broken twice on mine and repaired. Just off the top of my head, not the AC guru here, but those are two problems I have run into that sound similar to your situation.

No the engine fan is not running i will peal back the covering and check it in the morning. How would it being overcharged keep the compressor running when I'm calling for heat.
