For the past few weeks, the AC has been working erratically (works fine for days at a time, then at a seemingly random time, the air flow goes very low and very warm, then back to normal) again for a few days, or a few minutes. Like I said, it's random. With the codes above, is it just a matter of replacing the control module for a fix? If so, is this a difficult thing to do for a regular guy who's not a professional mechanic? Thanks guys.
