    A few days ago while driving AC In the front started blowing warmer and warmer air. Now blows hot and sometimes slightly cool air.

    The dash diagnostics I’m getting when I turn AC on is SSAM 520640 AC compressor circuit open.
    Did battery off for 15 mins reset, did AC reset and checked all AC related fuses. AC compressor is visibly operating/spinning

    any ideas what I could check?
    By the way a couple of days after this started I ended up having a battery go bad and had to replace4 of them that day. Voltage looks normal 14.1-14.2V
