I opened relay boxes not knowing what was what and abs relays smelled too its up front pass side next to radiator. 3 relays in it and it smelled. So idk whats going on with it. I love the car has 190 on miles but purrs like kitten till this ac crap

Thank you. It sounds like the AC compressor failed. When it fails and seizes up this will occur. The clutch may have melted internally which will cause this noise and the smell that you got. I usually remove the belt and spin it by hand to see if it is binding. If it is then it needs to be replaced.

Ok ill try that in morning. Can just clutch be replaced and fix issue or just buy a compressor. Which then i got take freon out
Expert:  FIXITMAN replied 1 year ago.

You will need to replace the entire compressor on this vehicle to repair it correctly.

Ok thanks do u have a estime on time or other stuff i have to take off to put it on.. i dont mind getting dirty but like to have a game plan at it any speacial tools too

It is not terribly hard to replace on this car. It should take a few hours to do. The compressor itself would be the biggest expense. Also make sure that the metering valve and the drier are replaced at the same time.
