I thought the system needed to be recharged so I took it to a shop. They said the system had a full charge and the compressor comes on and stays on, and they didn't have enough info in all the data to continue. So they said I had to take it to the dealer or a specialist. If you have any idea what this could be I would apprieciate the help. Thank You

Does the ac compressor run continuosly even in the "heat mode"? If yes, pull the ac compressor relay. Does the compressor stop? Please advise.

There is a connector on the AC compressor clutch. It may be a little hard to get to, but unplug this connector and see if the compressor stops. If not, try to turn the very front part of the compressor clutch and see if it turns. The compressor clutch may be stuck together.

I disconnected the plug and it was still running, and I tried to turn the front part of the compressor clutch but I can't turn it.

OK, it appears your compressor clutch is locked up. It takes a special tool to change it. You will probably have to take it to a shop for confirmation.
