Engine Mechanical problem
2002 Ford Taurus 6 cyl

Serpentine belt, one pully is NOT turning any more. Looking from the passenger side of the car, the unit is on the right (front side of car) and on the bottom. It's held in place by three bolts in a triangle pattern. The belt is turning, but is dragging across this unit so it's starting to smoke and smell of burned rubber.

What is this unit?

Based on (see attached image)

It's the AC Compressor.

Ugh! $199 and doesn't look easy to replace.

Hello,

Yes it is the A/C Compressor. And you would be better off taking it to a garage you trust. They will have to evac the system of all old freon before replacing the unit. You are probably looking at around $500+ for repairs.

You might try unplugging the electrical connection at compressor clutch. If it doesn't unlock, it needs a new clutch at minimum. Takes special tools. Good luck

I unplugged the power connector coming out the top of the compressor on its right side (looking from the front of the car), is this the clutch area?

Also is there possibly a fuse issue? What fuse is for this compressor?

If it didn't unlock, take it to a reputable shop and have at minimum a new compressor clutch installed. They can tell you if the compressor is bad or if it's just the clutch. The owners manual will tell you where the fuse is.

I was checking before I started the car :)

OK. So the fuse is #33, found the diagram in my manual. Started the car and the unplugging DID in fact unlock the clutch. I let it run for about a minute and no more locking.

However, what could possibly have caused this lockup in the first place and what should my confidence level be in using the car now?

It has never happened before.

Likie all things mechanical, it works till it quits. It'll need to be diagnosed professionally to determine if the clutch or compressor is faulty. There are bearings in the clutch that could have failed or the compressor might have failed. At least you aren't smoking belts anymore. Good luck

OK. More info/details.

Like I said, pulling the power worked, the thing unlocked. I just drove about 20 miles and it worked fine. WHEN THE HEATING/AC was OFF. Completely off. I guess the compressor pulley spins freely when it's off. When I turned it on for defroster, it started making odd noises and acting like it was going to seize up. Turned it OFF and everything went back to "normal".

So at least I can drive it to a mechanic if need be.

But does this info change any diagnosis or trigger any more suggestion?

If it is locking up when engaged then it sounds like the compressure is locked up.

When the clutch engages it turns the shaft that pumps the freon around the system. When disengaged the pulley will turn freely.

When your defroster is on, the compressor is supposed to pump fluid around. It keeps it from seizing in winter when ac isn't used. If it locks up then the compressor has failed. Unplug to use and be able to use defroster normally. These guys are pretty good.
