1992 Mazda 929 Q&A
1992 Mazda 929 Question: What would cause a loud squeal inside ac air compressor at start up?
compressor bearing may be failing. have it checked before it locks up completely. Roy - mastertech6371
Did the squeal start BEFORE OR AFTER the 'belts and water pump' replacement? Does the noise only happen (or happen worse) when A/C is on? Are belts good grade , and properly tensioned ? OR I could be WAY off base and the compressor's screwed. I hope not for your $ sake. Good luck. - ziptie12
