Seems to cycle properly, but i do not have the A/C button pushed to the on. When i turn the blower motor to off the compressor does turn off.

Welcome to 2CarPros.

Either you have a short to power, or the defroster is on. When the defroster is on, it uses the AC to help dehumidify the air. Is that a possibility?

Let me know.

Welcome back:

You are very welcome. That is a common concern. Most people don't realize the defrost uses the AC to work better.

Take care and let us know if you have questions in the future.
