My A/C made a strange squalling noise tonight and just wondering if anyone has any insight. I started my Lexus Lx450 with the A/c on and everything was great, I drove it about 300 feet to the mailbox and turned off the engine walked to the mailbox (Apartment Living) and when I started the engine up after about 5 minutes the A/c Belt was squalling real loud. I turned off the A/c and drove the gas station when I get there I had the press the A/C button while I was under the hood. I saw that the A/c condenser did 1 revolution with a lot of belt slipping. A hour later I tried the A/C again and it work just fine the rest of the day. Any ideas/
