To better help you with your problem, always put the year,make, model, & engine you have in 1st post of each thread you start.
You can test compressor clutch by removing ac compressor relay in underhood electrical center. Put a jumper wire in terminals 85 & 86 where relay was. That would be the terminals with a pink wire & a dark green/white wire.
Turn ignition switch to on. Compressor clutch should engage. Let it stay on for about 10 minutes. See if it starts sparking and/or smoking during this time. If yes, you've found the problem. If no, turn ignition off, Keep jumper wire in place.
Remove serpentine drive belt from compressor. Spin pulley by hand. It should spin freely, but still have a little resistance because of the grease in the bearing. If it passes test turn ignition back on.
Compressor clutch should engage again. Spin compressor clutch by hand again. It should be very hard to turn it with clutch engaged, but it should spin by hand. If you can't move clutch now, compressor is most likely no good. If it does spin move to next test.
Put belt back on.
Start engine, turn ac on. Cooling fans should come on and compressor clutch should engage and ac work. Watch compressor and belt for signs of failure.
