Thank you for the breakdown!

[@melindawhitakerlancaster1756]

This was bad ass very easy to follow

Thank you so much. The issue was indeed battey not getting adequate voltage. This was due to a faulty phone charger that I was using. As soon as I removed the charger, AC started blowing cold air.
Keep up the good work.

I have a faulty AC and dont need it and dont want to repair it. It is constantly running, I can't switch it of. Can I dissble it by removing the AC fuse?

[@jgconnelly]

Yes.

4:20 blown fuse... can a blown fuse still have ac blow cold air every morning for several hours before blowing hot air?
