2001 IS300. Really disappointed, just spent close to $50 on a can of AC Pro with the gauge, followed all the instructions I've seen on here and no dice. Car is blowing hot air and its hot as hell here. I've attached an image I found of the location of the low pressure side, is this not it or something?? There was no cap on it, I think it broke off if there is supposed to be one. Anyhow I turned the car on cranked the AC plugged into the port shown in image, the pressure was about 25 psi, so I pulled the trigger and rotated the can back and forth and kept checking the gauge until it got to about 45 psi or middle of green on gauge. The can is about empty at this point. I checked the air and still blowing hot. I then turned the car off before removing it from the AC port(which maybe I was supposed to remove it with the car still running??). When I removed the plug(with the car now off) it started violently spraying out of the AC port shown in image. What the heck did I do wrong?
