Yep, it looks like the A/C compressor is going out, the high side is too low. How much refrigerant is in the system? There should be 1.7 pounds.

Here is how to change the compressor out with instructions below for your car:

Yep, the receiver dryer can be tough to get to, I would open the system after the refrigerant has been removed and see what it looks like, there are two ways a compressor with stop working, messy and not. I other words are the compressor seals spread throughout he system or is the system clean inside, this will determine if you need the expansion block or not. You can upload an image or video of the inside tubes once apart so I can tell.

Turns out the system is leaking. Added dye but not showing up yet. Going to check again within the next few days to try to find the dye. If the leak was in the evaporator core would I see the dye?

Yes, you should be able to see the dye. If the front of the compressor is leaking, which is common it can be difficult to see.

Can't find the dye leaking anywhere so assuming it's leaking in the evaporator. Is it worth trying a stop leak product?

I have not seen those work but you never know, if you have a leak detector and can sniff the evaporator drain tube as in the guide above.

My mechanic claims I don't have a leak but the compressor is gummed up with garbage so it would need to be replaced. I've decided to do it myself. Would you recommend replacing the condenser drier and expansion valve as well?
