Use an OBD2 code scanner to find out what's wrong with your vehicle. It will tell you what's wrong and let you clear the code when you're done. If the problem hasn't been taken care of, the computer will set the code again. BTW, why would you replace parts that weren't causing a problem?

AC compressor - clutch seems to be locking upmaking noise can only the clutch be replaced or does the entire Compressor need to be replaced?

If the AC pulley is locking up when the ac compressor clutch engages, it's not a clutch problem, it's a compressor problem. But yes, the AC clutch can usually be replaced separately. The problem is, if the clutch is worn out the compressor is probably worn out as well. It usually isn't that much more to replace the whole thing.
