I went to drive the IS today and the A/C was blowing hot air. It was working perfectly fine the previous time I drove it (which was about a month ago). I'm hoping it just needs a recharge since it was sitting for a while and working perfectly before. Anyways, I used a gauge that came with a recharge can and it showed that the pressure was high with the A/C on. The clutch does visibly engage and disengage when the A/C is turned on and off respectively so I'm wondering why the gauge shows the pressure being so high on the low side port. The gauge shows high when the A/c is on and off, which has be concerned because the 'Ez Chill' instructions state to take it to a mechanic if it shows high with the A/C on. Does the IS300 compressor have a special feature which won't let the compressor turn on if its low on refrigerant? The sight glass near the headlight doesn't show bubbles (or possibly nothing at all). Would a simple recharge solve this issue or is there a mechanical issue with the compressor?

Thanks!
