Screeching Ac & Startup


Recommended Posts

97 LX 450 w/ 70K miles. Had it 6 months. Last 2 months I noticed a screeching sound on startup. Lasts less than a second. Sounds like a belt or bearing. In the last week, noticed same sound every time AC compresser cycles on. Occasionally the noise does not stop until I turn off AC then turn on again. AC works great.

Any ideas?

I had planned to have mechanic replace all belts/hoses, but at $1,000 I am trying to wait as long as possible.
