Here's a possible test:

The idea is to get things so that you can turn the pulley by hand, with clutch engaged, in order to detect if the compressor internals are dragging or attempting to lock up.

To do this you would have to remove or severely loosen the a/c drive belt, and jump the low-pressure cut off switch. Then with the key in "Run" and the a/c on, the compressor should engage if (1) the time delay has elapsed, and (2) you jump the low pressure switch.

See how easily the compressor turns. You can tell if the pulley/clutch are engaged. If the clutch is not engaged, the test is meaningless.

Good Luck,

Bob
