Hey, new to cars be gentle. I tried recharging my ac on my 2002 Lexus gs300, I turned the AC as low as it can go and set the blower as high as it can go. I checked the compressor was spinning so I put on the bottle and after about 2 seconds of charging the bottle told me it was at the correct charge but my ac is still blowing hot air. Am I stupid and doing something wrong?

Are you shaking the bottle as you put it in? Did you set the dial on the bottle to the current ambient temp?

If so, then the problem isn't in the charge of the system. The compressor could be bad or you could have a blockage anywhere in the plumbing for the AC system.

You may need to just have it recharged professionally. Without vacuuming out the air, pressure would be incorrect and very high if mixed with air.

Agree. With this aging generation, it's best to have it professionally tested / charged. So many things can be bad / wrong keeping the store bought route from working in the slightest. Another reason a trusted mechanic is an absolute must these days...

Thank you all so much for the help, I'll have it looked at professionally.

Did you pull a vacuum before you recharged it? I would also recommend you get it professionally recharged because they will put in the correct amount of oil and refrigerant in the a/c system. Those DIY a/c cans 99% of the time will never turn out to be the correct amount of refrigerant your particular vehicle requires.
