Hi, I have a Corolla S 2001 since oct 2013 and for the first time I've had to use the AC and I think it's either broken, or has no power.
There's something that I always found weird, even with the AC turned off, switching the temperature in the Temp Knob will change the temperature of the air coming out of the vents (if I turn on the fan of course). Even when it was a little hot outside, if I set the temp knob to the coldest, the air coming out of the vents with NO AC turned on was way colder than the air outside; which I found weird cause I'd expect that if no AC is turned on, the air coming in would be as cold as the air was outside (or actually even warmer cause it has to go through pipes or whatever)
Maybe that's the way it works and it always has some sort of "AC" turned on all the time (which I'd like to know how it works cause if it is turned on is draining power)
The problem I have is that setting the temp to coldest, and TURNING ON the AC, doesnt change ANYHTING, I tried it for like 30 minutes with AC on, no changes, i turned off the AC to see if it changed, nothing.
I cant find my thermometer so I can't know for sure if the temp is changing, but I'm pretty sure it's not even changing 1 degree.
How does the AC button work? Is it possible I have something wrong with my AC unit? I know for a fact that it has never been fixed/recharged/upgraded since the car was manufactured neither by me or the previous owner (one of my best friends )
I've read that recharging the AC would help get the air colder but before I even do that I want to understand how it works, cause right now, it feels like the AC button is just there for display
Thanks in advance for the help I always get in this forum, I know I ask a lot of questions but I love my car and want to get it working as good as possible both performance and comfort wise
