My air conditioning has been working fine. Yesterday when I was driving I had both sides in the front set on 60 degrees. The driver side started blowing hot air, but the passenger side kept blowing cold air. After it sat over night, it has worked fine today with both sides blowing out cold air when it is set at 60 degrees. Any ideas on what is wrong?

Thanks in advance.

Check system for a full charge.
Post back low and high side readings at idle and at 2K rpm.
