I've noticed that my car has been running remarkably cooler this year, even in the heat of the day. Straight up needle, rock solid. But, my a/c was less and less effective, barely working. I had the a/c checked out, no leaks, compressor is running like a champ. No problems that they could find. It was 2lbs low on freon, so, rather than convert to less effective freon, I had it recharged with R12. It didn't work when I picked it up, so they "put more vacuum on it" and it blows like friggin' ice now without even being all the way down.
What I've noticed since then is that the car runs a little warmer. Not alarmingly warmer, but it gets up to the middle of the "M" (wish there were temp degrees on the gauge), where it used to be straight up. Does the work on the a/c put more drag on the compressor causing the heat by slowing things down? I wouldn't think it would do that, or at least not enough to raise the temp.
Is that normal?
