FJ62 A/C clutch?

[meatsauce]

the pulley for my a/c is squealing. when i turn on the a/c it goes away. i think the clutch might be on its way out. is there any way to test or diagnos it. i have the FSM but it does not cover troubleshooting. any thoughts ? thanks

The clutch just engages or dis-engages the compressor. If it does that it's OK.

If there is squealing I'd first suspect a loose belt and then an idler bearing.

There is a bearing in the A/C clutch unit.
When the A/C is turned OFF, the clutch pulley is rotating on that bearing.
When the A/C is turned ON and the clutch is engaged, the clutch pulley is rotating on the compressor bearings.

If there is a sqeal from the A/C clutch when the A/C is off and it goes away when the A/C is turned on, then it is most likely the clutch bearing making the noise.

I would check for loose belts before doing anything else.

You'll need some good snap ring pliers and make SURE you don't disconnect the A/C hoses. It shouldn't be too hard to do. If you disconnect the A/C hoses you'll have a recharge bill to add to everything else (not something that should be attempted by the average backyard mechanic).
