I sent my car in to troubleshoot a growling noise the AC was making. After about an hour, they took me into the shop to show me what was going on.
The low pressure side was too high, and the high pressure side was too low. And when the engine would rev, these would not budge. They said it was a bad compressor, which I agree, and they quoted me almost $1000 to fix it. I looked at what they quoted, and I can do it for around 1/5th that.
So I have a few questions going in. Numbered them so you can reference the numbers.
1 - Do you agree it is a bad compressor? It seems pretty obvious, since a bad compressor wouldn't be able to maintain a pressure differential.
2 - How likely is it that there is a leak elsewhere in the system, and that this caused the compressor to overwork and go out? How would I check?
3 - I notice it is recommended to change the accumulator/dryer. What is the difference between an accumulator and a dryer? I noticed two tank-looking parts. The large one is obviously the accumulator/dryer, but there is also a small one that exists between the compressor and the accumulator.
4 - Are there any products/kits you can recommend? I've been looking at Amazon, since I get free 2-day shipping. I see a lot of options, and some good kits with all the parts and gaskets. I just wasn't sure if there is a huge difference between products. Same goes for coolant brands and compressor oil brands, if there are bad ones to avoid.
