Ya'll...I'm confused.
Yesterday I recharged the a/c in my car (feels great!). Then I proceeded to have some overheating issues ALL day. At speed, at idle, everywhere. on a clock-type guage, normally the needle is just to the left of 12, it went to about 12:30/1 position at most. I had to go over 2 mountains on my way home (rte 211). I overheated on first one, pulled off, and I had no coolant leaking anywhere. I did notice quite a bit of clear liquid coming from around the heater core area, and then noticed that the a/c lines were condensing like crazy. Which is weird, because the a/c switch hadn't been on in over an hour. I had noticed some water dripping the other day, but didn't take much note of it, but now it got me thinking...Is my a/c on despite my switch being off? So I unplugged the a/c comp from the harness, started the car, and then plugged it in with the switch off again, and boom, a/c comp kicks in. Also, both fans are running....So, a couple questions:
Would a constantly running (not cycling, just ON) a/c comp cause the car to overheat? I know these have relatively weak cooling systems, but I feel like the cooling system should be able to keep up with the a/c. but what about if the a/c is constantly running?
Why is the a/c comp on, when the switch is off? Relay? interior switch? A/c clutch or comp?
Moreover, now the car feels completely different. Like it has a few extra hp (makes sense, since the a/c is DEFINITELY off), idles quieter, runs smoother, doesn't stall sometimes coming to a stop.
I also noted this morning that the heater seems to work differently. Up until this morning, if I had the heat on anything other than full heat, the upper vents would blow colder while the feet vents were blowing hot. Now, there is much more variation in the heat level on the upper vents.
I believe the a/c has been stuck on since I bought it, but it hasn't been a problem since it's been cooler. Suprisingly, there is very little on a/c's being stuck ON in miatas, usually they are stuck off apparently. Has anyone had experience with this type of issue?
