I have only noticed this once before - when I accelerate from a stop with full throttle I get what sounds like a slight belt squeak and then no more cold air until I lower the temp to max and then it comes back cold again in a few minutes. I have a new belt, tensioner, pulleys - and the a/c works all the time here in South Florida. Could I have low freon? I know there is a full throttle cutoff for the compressor - how can I check to see if that is functioning properly? This only happens from a stop with full throttle- kick down and first gear engages. This is for a 1992 300sl so it is never quick from a standstill.
