Im trying to replace an ac compressor cluth with a bypass but cant find anything that tells me how

The major autoparts stores sell a bracket which uses the same boltholes as the old A/C compressor. It has a free-wheeling pulley and should use the same belt.
There are a few potential problems, I see, which may be noticeable in engine idle speed. When A/C worked, or Defroster, the drag of the compressor running was to be offset by a bump in the RPM to offset drag. You will need to tidy up the loose hoses to keep them from dangling in the engine compartment.

Noise from ac compressor

That would depend on the problem and prices in your area.
You can call around and ask for the cost to replace the ac clutch and the compressor.
If the bearing in the clutch is the noise, the clutch can be replaced without replacing the entire compressor assembly.

I have a 99 grand marquis the a/c still blows could but it only blows hot air how do I fix this problem

If the blower works but no cold air, a mechanic would check to see if the system is low on freon, then check for voltage at the low pressure switch and the ac clutch as needed.

2000 grand marquis turned ac on and car died

The compressor could be locked up which would stop the engine when the a/c clutch engages.

How do I replace the a/c clutch on 1998 grand Marquis

The AC clutch can be replaced but the logic for doing so isn't good. A remanufactured Compresser with clutch cost very little mare and the compresser being bad is very likly to be the cause of the bad clutch. Once you installed the clutch its yours and you'll lose its cost if you still need a compresser. Change the compresser it's not worth the difference in cost
