I heard a noise when I got in my car yesterday on the way to the market. The trip as only about 1.5 miles. On the way back I could smell some one burning rubber. I could still smell the rubber when I walked to unload my groceries as I passed my car. This morning after everything had cooled I thought I would raise the hood and take a looksee. I started the car and everything appeared to be ok. I did notice a reddish substance coming from the A/C pulley wheel. (I looked at my Ford Chilton book to find out what I was looking at, an A/C Unit). As the car was running I decided to turn on the A/C unit. Shortly after I noticed that the pulley stopped tuning so I immediately turned off the car and readied the garage for a spot to park it. I pulled it into the garage and decided to give you a buzz to get some more info.
I need to know how to repair this problem. Just a basic A-Z would be nice. Recommend a book or tools techniques. If I should use e rebuild unit. What are the environmental implications of repairing this pulley? Is the entire unit in need of replacing?

Hi:
If the pulley locked up, the compressor needs replaced. The only environmental issues deal with the freon in the system that will be discharged when you remove the hoses to the system. Other than that, nothing. Regardless, in most states, the freon needs to be pumped from the system before this type of repair can be done. It requires special (expensive) equipment.

As far as unbolting the compressor and replacing it, you should have no trouble. But it will need vacuumed and then recharged. Also, check the warranty on the remanufactured units. If they provide a good warranty, don't be afraid to go that way.

So the clutch and the compressor will need repair. Will the drier or Accumulator also need to be replaced since the unit is now accessible? Any type of refrigerant oil needed to be added? Recently lost my job and time is on my side but I want to keep this car.
Thanks for the quick reply.

Can you give me any technical manuals or techniques to use for the repair? I have a Chiltons 1991-97 book but does not cover my specific needs.
Thank you,
Pete

The car is in the garage at my house. How do I get the freon pumped into an authorized system? Is there a tow truck in my future?

PETE:

Does the pulley lock up if the AC and the Defroster are off? It shouldn't. If it doesn't, you could drive it. Keep in mind, the compressor runs when the defroster is on too.

As far as the manual, we use an online manual and I can't copy and paste anything. The freon removal should be done by a certified mechanic that has the equipment needed. As far as R&R the compressor, you should be able to do that.

Let me know if this helps. Also, (I never looked at them) there is a site link on this page for manuals. Check it out and see if it can help you.

Let me know how you make out with the problem or if you have other questions.
