2002 Lexus RX 300 6 cyl Front Wheel Drive Automatic

When I first start up car there is a noise coming from the AC compressor or altenator or power steering pump it sounds like crickets but stops after engine has been running for about 20 minutes and will stop if rpms are above 2200. If it is the AC clutch can it be replaced without taking the comprssor off?

If it is the A/C then it's probably the pulley bearing. Problem is, most aftermarket clutch and pulley assemblies are a bit larger, and requires the removal of the unit to change the clutch. If you can find a good one in the junk yard, you may be able to swap it without opening the system. Remove the serp belt and spin both the tensioner and idler pulleys, these are more common problems than the A/C. Any roughness while spinning them means replace!
