Air Compressor Rattling

Hey everyone,

This is my first post, so go easy on me. I tried searching, but found nothing.

The vehicle is a 2004 expedition 2wd with the 5.4 engine.

The air conditioning compressor is rattling like crazy!! It is blowing really cold, but living in Vegas, I want to fix it before it goes out and me and the fam. are stuck sweating....

I am pretty mechanical, but not good at diagnostics. Any ideas would be appreciated.

I think it might be the compressor clutch, however, I don't know if this can be changed without changing the entire compressor.

Thanks.

Ryan

oh yeah I should have been a little more clear on that. The rattling goes away when the a/c is turned off.

Re: Air Compressor Rattling

i would say the whole pump is about to bite the dust which is a drag because that usually means metal shavings from the dying pump have been distributed throughout the system. this means a new orifice tube will be needed(cheap) and a new accumulator or receiver dryer(depending on system design) should be done plus flushing the rest of the system.
