ac clutch

You should replace the whole unit- around $1400. I say that because if you only replace piece by piece with an A/C unit all it continues to shorten the life span of the entire unit. If it was a belt, yes, but clutches and compressors, just replace the whole unit.

I’ll add to this even though the post is a few years old- Run a decent scan tool to pull codes, and see if you have a B1479 code. The sensor inside the Corolla compressors are prone to failure, and I just had to replace mine. Check voltage at the connections 1st to make sure it’s not e amplifier! I spent 400$ to replace the compressor myself. Used RockAuto to buy a new 4 seasons compressor, dryer desiccant, oil, and new belt. Local shop only charged me 18$ to recover the Freon and pull a vacuum, recharged using 2 cheap Walmart cans of 12oz r134. Only used part of the 2nd can and was showing the correct pressure values for ambient temp.
