How to replace A/C Compressor on 2005 Mercury Sable Sign In

   
2005
Mercury
Sable
3.0 - 24valve DOHC

AC quit working and squeeling noise under the hood. Took it into the shop and was told the A/C Compressor is bad.
Quoted $1,200 for factory recommended repair. Quoted $750 for only A/C compressor replacement. Cost to me to diagnois
the problem and get estimate was $75 which would apply to repairs if I had that shop do the work. Contacted Autozone
and got pricing for a A/C Compressor w/ Clutch for around $200. When asked why the estimate to just repalce the A/C compressor
was so high, the explaination I got was that because of the width of my engine (DOHC), replacement was more time-consuming and
involved dropping the engine to change it. Is this guy blowing smoke or speaking the truth? I'm inclined to tackle the job myself,
although I'm a computer guy, not a auto guy. I had the shop evacuate the A/C system as part of my $75 diagnostic fee. They
were a little surprised I didn't just have them fix it. They asked if I was going to have them refill the A/C. I said maybe - what's the cost?
They said $106! Right now the car is in my driveway and A/C is evacuated. I have an alternate car, so there is no time crunch to repair this.
I really want to do this myself and save $$$. Worst case scenario is I can't do it and have to take it back in to have the shop fix it? Seems
like it is worth the try. Can anyone help advise on tools needed, procedure to follow. I have a Haynes Repair Manual fo r1996-2006 Ford Taurus and Mercury Sable. What worried me was the comment about having to lower/drop the engine on this particular make/model to replace the A/C compressor????

I can post digital pics if needed.

Please Help!

Sounds like compressor seized so it's not just a compressor replacement as that won't work. It may have suffered the "black death" and lots more needs to be done or a new not some junk rebuilt will fail right away and no warranty if not done to spec.

Think hard about whether you really want this or not. We are here to help but it's nothing like just swapping out an alternator whatsoever.

Do read this link at this same site above this thread.......... http://autoforums.carjunky.com/..._A/C_SYSTEMS_P45460/

That's what you need when everything is done and perfect just to charge it. Alone that a college course never mind complications. Think about it and the equipment needed and risks involved,
