adman@nefco Posted September 6, 2003 Share Posted September 6, 2003 I have a 2004 Rx 330 Sport. I noticed a buzzing noise coming from the engine when the A/c is switched on as the engine speed is reducing from 50mph to 20mph. They said it was a compressor problem , when the coolant is being bled out. They replaced the compressor and it was acceptable initialy.I am now finding this problem is coming back . Any other people haveing the same problem? Anyword from your dealer on this ? Quote Link to comment Share on other sites More sharing options...
