Changing just the clutch in an AC compressor good idea..??
Been having issues with my AC compressor not kicking it, blowing fuses, etc..Every time the compressor engages, it blows the fuse and cuts off. refrigerant levels are not low. No shop wants to touch just the clutch and want to replace the whole compressor. Can't afford to pay $500-900 for a compressor replacement. The compressor isn't locked up and can be spun by hand. Luckily, I found a clutch on Amazon for $40 and was wondering what you guys think.

Replacing the AC clutch sound like a good idea, however..
The high & low side refrigerant pressure must be within specifications for the compressor to kick in properly. What are the readings on the high & low side?
The clutch coil & associated wiring/connector (as it'* blowing fuses) could be a problem along with a rusted clutch.
I cleaned mine up with emery cloth and used silicone spray to free it up.
Do you get grinding sounds when it does engage, or any metal shavings below clutch seen?
You can also check the gap of the clutch and set it correctly if it is too tight etc..

Hope this helps.

If you are good with a DVM and it can measure AMP'*, make your own connector and supply 12v straight to the clutch with the engine running and measure the amps. If the power draw is less than the fuse rating, you have an issue with the harness somewhere.

UPDATE: Bought a compressor clutch from amazon. Took old clutch out, put new one in, tighten it to the consistency and AC blows nice and cold! Whole job took no more than an hour. IF anyone has 06-13 impala with ac compressor issue where it'* blowing fuses, I'd recommend first changing the clutch ($40) vs. AC compressor ($200-$400)

What did the old clutch coil look like? Was it damaged? I had this same problem many years ago. It drove me crazy. I tested switches, I tested wires, I tested connections.....on and on.....for DAYS and Days I couldn't pin point the problem. So much frustration. Where I made my mistake was when I tested the clutch coil for continuity. Continuity was good. So I figured it (the coil) was good. I should have tested it for resistance. For whatever reason, the clutch coil developed an unacceptable amount of resistance, the wire heated up, deformed the clutch encasement and.....yeah, started popping fuses.
Live and learn.
Glad you got your a/c back.
Anybody here ever do thier own a/c repairs for friends, family or to make a few extra bucks on the weekends......well.....
Those little cans or R134a are kinda expensive. Fifty bucks for 20 ounces......and 20 ounces wont fill a whole system. However, a person can buy a 30 pound tank of R134a for $200 from Autozone. No license required. I do it.....I made my own recovery tank from an old LPG propane tank because venting the old R134a out into the atmosphere isn't cool.

For the propane tank to receive the chemical, basically what I have is the propane tank with it'* original propane valve>>>>to a 3ft length of propane hose. At the end of the hose I attached the orifice valve from a regular R134a tank. I recycle it at a warehouse where they deal with all kinds of chemicals including different refrigerants from all kinds of things from vehicles, to industrial freezers, to residential a/c units......they collect/recycle other hazard wastes as well. Oils, liquid and aerosol paints, electronic waste, old tires, Farm/Ranch pesticides..
