You dont know it needs a compressor yet.  It is normal for it to tick as the clutch cycles on and off.  Is it an abnormal ticking?

Pull the DTC codes is the first thing to do, the AC will set codes when there are problems.  You can extract codes directly from the dash.  Post the codes here.  

Once we see the codes it will help.  

How experienced is your brother in law, did he simply add a can or did he use a machine to evacuate the recharge it?

Find a good AC shop, have them evacuate the system, or pull a vacuum to dry it out and recharge it, I think it takes 2 pounds of refrigerant.  Have the shop put dye and an oil charge in.  The evacuation may find an leaks if they are unable to draw a good vacuum.

I went to Ac shop and he put gauge on and said the my compressor was not putting out anything he said . I want to go with a used one for 40 it's already pulled been sitting in a container off a 2000 sls and change the dryer but I'd that don't work I'm sol don't have the funds to re do it this shop said he'd but the part and the labor vacuum the lines arc all for 380 . I don't know who to trust they think cause I drive a Cadillac with Roma I'm rich ?

I agree with @BodybyFisher you don't know that you need a compressor yet.  The compressor won't run if it is low on refrigerant until it gets reset.  The mechanic may have been able to validate that the compressor was bad, but from what you are describing I don't feel much diagnosis was done.

 You mention you don't notice any codes -- are you checking for codes?  What codes show when you check?  The purpose of the diagnostic trouble codes (DTC) is exactly this situation -- to help understand what is wrong.

What was the status of the systems charge when it stopped cooling and the AC shop examined it? Keep in mind that your bro in law put a can in, causing an unknown refrigerant status

How did you check for codes, go to the HOW TO section here, and go to DTC codes and pull the codes.  These systems will not operate good unless evacuated and charged properly.  

What did the shop say about the refrigerant charge?  Those cans people put in are not the way to go, bandaid fix.  How reputable is this shop?  An evacuate recharge is about $150.  

Where in Texas are you?

Wait for @KHEto pop in if you can.   You might PM him if you want and direct him to this thread.  He is familiar with AC technicals and he should be able to give you some direction. 

If you can post a link to the sound that would help.  Load it up to photobucket and link here.  

Post EVERY code you are getting!, regardless of type.  DO NOT, I REPEAT, DO NOT use a code reader, only read codes through the dash, there are codes there that a simple code reader does not get.

IMO you should find another person to diagnose the problem. It appears that no leak test was performed. Was the charge that was added done by machine or one of the auto part stores "quick fill"? The system could be over charged with R-134 and/or oil. Only time I've ever had to replace a receiver/dryer is if the compressor came apart and scattered debris throughout the system. The orifice should be checked if that is the case.

What are the low and high side pressures? Has the A/C been turned off because the computer seen a problem?

TOO MANY questions not enough answers. Fire the guy....

HT-6/HR-6 compressor failures are extremely rare - not to say they don't fail internally but I don't think there has been such a failure reported on this forum.  The ticking noise you reported coming from the compressor may be a clue to the problem.

The most common failure mode of the HR series compressor is the case half seals leak due to corrosion on the ends.  The low charge will disable the compressor to keep it from being damaged.

What were the high and low side readings with the compressor engaged?  That would be helpful in diagnosing the problem and would confirm if the compressor reed valves were intact.

It still sounds to me like you have a bad AC shop or a friend is working on it.

What brand of compressor did you buy?

Most new compressors REQUIRE that you at least flush the system for the warranty.  

You should pull the orifice tube and see if there is debris in it. .  If yes, the condenser should be replaced and the system flushed.  I would also replace the drier and orifice tube if there is debris.  

On the other hand if there is no sign of debris and you just have a bad hub bearing you might just flush and replace the drier.  

Make sure that the right amount of oil is used. 

Is it physically rubbing up against something or is the HUB bearing bad and the hub is binding and making noise?  Please be clear

This is what I mean when I say you appear to have a bad shop, this kind of stuff should be very clear to a shop.  Have you taken it to a shop or are YOU doing the work?, it helps for us to know that.    I thought I recalled your were taking it to a shop.  Please answer my questions for us to better understand what is going on.

Sorry SS but I can't quite figure out what I am looking at. I maybe can see a clutch plate in the lower middle of the pic but I can't be sure. Take two pics or more, one from a wider angle and then the close-up.

Then if I'm looking at it correctly it appears to be a plastic splash shield rubbing the compressor clutch

watched the video about 10 times and don't see it rubbing anything, I do see something shiny but can not see what it is or if anything is rubbing from the angle.   The entire time the video was running the clutch didn't cycle, does it cycle?

I don't see the hub wobbling at all, and the hub bearing is not making any unusual noises.   I had one go on a 96 deville and they can get VERY noisy.

I don't see anything wrong, if the shop says its not performing properly that's one thing but I cant hear or see anything unusual. 

Lets let others see what they think.

If you are replacing the compressor I wouldnt worry about it.

Has the compressor produced debris?, have the shop pull the orifice tube and look. 

If it has produced debris replace the condenser.  But replace the drier and flush in any case.  Add oil and dye.

Thanks Mike :)

I agree with BBF in that video there is nothing rubbing.

The clutch is engaged but it appears the gap was wide and the plate had to travel a long way to engage so the "fingers" of the clutch appear to be wobbling but I don't think that is the case either. 

Get the right front wheel off the ground and remove the wheel, the splash shield and then take the video from the wheel opening. Have someone turn the a/c on and off while the video is playing.

Is this the original compressor or the replacement?

I don't know if it's the original . I'm sorry guys . I went to the shop today just to try and get a lil more fill for the guy he said my compressor was in he walk up to a rack and this used compressor is sitting there all oily and in the wide open I'm like no I don't want that I want a new one I thought we had that clear ? So I go inside we order a different compressor remanufacterd one for 185 but warranty his work if I would have bought it new I would have been closed to the same price but the work (labor ) wouldn't be warranted so I kinda in a mix but the total was 444 for everything compressor 90 day warranty  labor warranty in case if he has to take it off for some reason the freon flush the lines etc. does that sound ok I've got quotes up to 900 Dollars on this thing so he send the Ac Delco he had back it was off a 2002 devile I have paid for labor I'm thinking off trying to get someone else's second opinion but I work so much it hard to find free time

The compressor is running, we don't know much more than that at this point. 

Have this "guy" who is trying to sell you a compressor put gauges on it or hook it up to a R-134 machine and take a pic of the pressures with the compressor engaged and the temp set on 60 (max cold). Post those pics here B4 you authorize any work please...

Too much freon (R-134) will cause this -- that is why we need to SEE the pressures...

DO NOT let any refrigerant out

Ok so a guy at work had a gauge from his last can of freon he added we put it on my car to see if it had any pressure very very little came out there was no freon now I'm lost ?.... I just put plenty in maybe I blew a seal when I put to much in cause there not much if any in the system meaning all I had put in leaked out the next day cuase that's when it started blowing hot . So what do I do now guys
