AC Clutch Failure - How to fix! (blinking light, squealing)

That makes sense why they had a pic of mahle and Delphi, send a Delphi, and RockAuto lists those plus more

 

They're not an exact match but it's looking pretty promising at a glance. The pulley has a thicker section on the clutch side but when I have more time I will either do some measuring; or just throw the thing on and see how it lines up.

 

Sad to report that my gift to you guys this holiday season is taking one for the team - this does NOT work.

It bolts up and looks fine, until you look from the side and the gap is probably 4mm+ even without any shims - I believe spec is .3-.6mm based on another post I saw here. I "resurfaced" my original with some 400 grit on some tooling plate and reinstalled. I'll try to sell it in the 3G section but if I don't get any takers I may say screw it and have one of the guys where I work try to massage/MacGyver the front plate to see if I can salvage it..

EDIT: You can see in the pulley comparison photo that there's some extra "meat" on the old one - this is probably the culprit.

 

Thank you to the OP!! Had the exact same symptoms August 2021 - took it to the mechanic who charged me well north of $1500 for entire replacement of clutch assembly, compressor, refrigerant - everything. Fast forward to today - same symptoms again. Found this thread, ordered clutch assembly on Amazon (hub, magnet and pulley). Removed the clutch hub and a bunch of melted rubber pellets fell out, the things was essentially in two pieces. Saved the three shims that were in there. Put on the new clutch hub and voila - I have AC and defrost again - all in about 10 minutes. Just glad I didn't have to remove or re-install the snap rings. Feeling a bit disgruntled about the mechanic from 4 years ago, but they no longer will get my business
