2001 Dodge Caravan Engine Roars When Turn On A/C

It sounds like a bad bearing in the compressor. I would recommend a new one. On the Internet, you should be able to find a new one for around 250.00. If you get one from a salvage yard, chances are you'll end up with trouble.

The one from the manufacturer will be the most expensive. The others are aftermarket. Usually, there isn't that much of a difference, but it has to do with where they are getting it from.

I have a question. This post you mentioned rear AC. Do you only hear the noise when you use the rear AC?

Let me know.

No, there is only one compressor. I was thinking you may have had a bad rear blower motor.

Hi:
I just reviewed our conversations. Based on what you have described, I don't think it has anything to do with the rear. If you turn the AC on and the noise is coming from the front, it sounds like the AC compressor has a bad bearing. The bearing can be replaced, but by the time you add the part, and the additional labor to repair it, you are better off replacing the compressor.

Do me a favor. Aftermarket compressors can be found for under 300.00 dollars. If they try to charge you a lot more for the part, let me know and I'll direct you where to check for one. In addition to the compressor, they will need to recharge the system after it is replaced. I would expect about 1.5 hours labor + freon to recharge the system.

Please let me know if you have other questions or if you have questions about prices.

You're welcome. I'm glad to help. Let me know if you have other questions.
