I need some A/C advice
I have a '99 that has 155k miles on it and my A/C button on the NAV screen started flashing, then a message came up saying something about "check the A/C unit" blah blah.
So, I finally take the car to the local stealership and the service rep. tried something I've never seen before. He grabbed the front part of the compressor, he called it the clutch or 'magnet', and he tried to turn it.
He said it should turn freely but mine does not!
So, I left it for their service department and the diagnosis so far is that I need a new A/C clutch AND compressor for a whopping $1300 + $360 for labor. Ouch!
The car probably has around 250 miles on it since that A/C light started flashing.
I'm mechanically inclined enough to do any replacement work as long as no super special tools are needed. Can I do this myself? Do I really need a compressor or can I get by with just the clutch?!??
I don't mind doing the work and then taking it in for a freon check/fill.
What do you guys think?

Just replace the whole compressor with a used one for the cheapest route. You can do this yourself if you have the tools. The only special tool you will need is the AC gauge set and vacuum pump to vacuum and recharge the system after you take it apart. I would suggest getting your refrigerant evacuated at a shop instead of into the atmosphere, because one pound of R134 is eqivalent to 1700lbs of CO2 in terms of greenhouse gas release. The GS ac has approx 1.5lbs of R134 in the charge. Then again some people don't care, so its all on you lol.
Fun fact: Almost everyone has released R134 into the atmosphere all the time in great quantities without even knowing. Many aerosol cans are propelled by R134. If you ever bought a bottle of "canned air" to dust out the computer...that entire bottle is straight R134
Anyways back to the original subject at hand. You can fix it yourself with a used compressor for around $300 or so depending on how cheap you pick up the compressor for. The vacuum pump you can rent at most automotive parts stores for free. The gauge set will cost around $50-100 or so for a light duty set(cheap gauge sets works fine and are accurate, just not meant for heavy everyday use like in a shop). Other than that, you just need some basic ratchets, sockets, and wrenches. You will also need around 25oz or so of R134 and also some oil for the compressor as well.
Good luck on your AC adventures!

Hey Jeff. Have you ever replaced a compressor? I picked up a used compressor, but the dealer is telling me that they need to charge 7 hours of shop time to replace it. They said they need to remove the front bumper and take apart other things to get to it. Any idea if they're right?

trust me, nowadays its easier/cheaper normally to replace the whole compressor than to rebuild them. if the clutch fan is out just replace the compressor. although i have rebuilt a few in my life i would always much rather replace them. although being in the HVAC-R field im biased on the freon used.
i recommend a freon called hotshot aka 414-b
