Question about 1997 Lexus LS 400
1997 ls400 - air conditioner not working
First check if the compressor comes on at all when you push the A/C button inside the car while it running. if the RPMs don't move at all, it's probably not coming on.
Also, check all the fuses and make sure they are okay. Your user manuall will give you the location of the fuse.
Next, check the freon level. When there is not enough freon in the system, it will automatically keep the compressor turned off so it doesn't burn it up. One way to see is to add some freon to your system and see if it kicks the compressor on. You can buy a can of freon at any walmart, and you just need a hose to hook up to your "low side" on A/C system and add the freon while the car is running and the A/C is turned on. You will hear it "kick on" when it has enough pressure in the system.
If that works, and a few days go by and it quits, you probably have a leak somewhere.
