my 93 accord lx squeals when you start the car with a/c on and continues to squeal. I replaced all belts and it went away for about a day. Any ideas it's really annoying. It doesn't squeal when a/c is off.

 

Spray water on the belts to see if that changes it. Sounds like the belts are loose, if you can convince yourself that the sound IS coming from the belts.

Ordinarily I'd say old belts get hard & slippery so I'd warn you about over-tightening them. But you just bought new ones...
