I just had a special run ti Idaho Falls. Normally I am out and back home daily. When driving the wife was microwaving some potato's for dinner and all of a sudden the a/c started blowing warmer. I keep a temp prob in the vent cuz I like to see what the temp is coming out. The temp is normally 42* it rose up to 60*. I clicked over to volts on dash and it dropped to 12.5v. I was running 1300 rpm then dropped down a gear ran it up to 1600 rpm and volts went back to 13.9v and the temps went back to 40ish. I will be putting in an amp gauge this weekend to actually see what is going on. Just wondering why the a/c temp would climb like that is it controlled by ecm and lowered it because of voltage drop? Normally only run the micro for a min or 2 to warm lunch so this doesn't really matter, just wondering WTH.
