1999 T&C with very loud noise somehow associated with a/c or belt
I have a terrible noise coming from I believe my a/c compressor. It sounds like a box of marbles is attached to the pulley. Really I cannot tell where the noise is coming from. It started out as a softer noise (maybe a box of BB's instead of marbles) and it only occurred when I turned on the a/c and only when the engine was idling. As I would rev the engine it would quit. If I turned off the a/c it would quit. It was annoying but bearable and the a/c still blew cold air.
I took it in yesterday for an oil change and tire rotation and asked them to check the freon levels thinking that it might solve the problem. They told me levels where fine but it was only a matter of time before the compressor seized up. Could be tomorrow, could be a year from now. In my mind I saw the dollar bills floating away and decided I had better start saving up. Well later that evening the noise became 10x worse. Now it sounds like it did before even with the a/c off and if you turn it on it sounds like marbles. Could they have accidentally bled out the freon/oil in the system when they checked it and that made the noise worse? Why would it suddenly get so much worse, coincidence? It still blows cold but you can hear me coming down the road from a mile away.
Any thoughts? It is a serpentine belt system so it could be anywhere I suppose and engaging the a/c might change the rpm enough to cause a problem? The noise still quits if I get the engine over 1000 rpm.
Please help me figure this one out before I throw down big bucks ...

Re: 1999 T&C with very loud noise somehow associated...
From your description it sounds like a bearing in one of the units driven by the drive belt is failing. It's most likely the a/c compressor but could be a tensioner or idler pulley. The added stress of the a/c compressor could cause the noise to occur only with the a/c on. To determine which bearing is failing the drive belt would be removed and the pulleys spun by hand while listening for noise. It is just a coincidence that the noise got worse after they checked the refrigerant pressures. The part that is likely failing isn't oiled by the oil in the a/c system.

Oct 2, 2013 - I recently had new fan belts installed after hearing a high-pitched, ... Do you hear the noise when the engine is running and the vehicle ... Just replaced water pump (and timing belt) yesterday and squeal ... When driving it make a noise but change out and caught speed the noise is coming from driver side.Missing: 1999 plymouth breeze
This could be caused by different things. It sounds like it may be your timing belt though. If you remove your drive belts (alternator, power steering and air conditioner belts), and then restart the vehicle, if the noise stops, then spin the pulleys you just removed the belts from, to see which one is making the noise. If the noise does not stop, then it is most likely the timing belt tensioner making all that noise and you will need to have the timing belt and associated parts, idler pulley/s, tensioner, water pump and seals replaced. Hope this helps. Have a nice day :O)
Sounds as like the accessory drive belts are either loose or in need of replacement or both. The noise you are referring to is from the belt(s) loose on the pulley and when you are accelerating the belt begins slipping at a high rate.
is your ac compressor located on the left side as well and also try your ac if its not blowing to cold the rattling could be your ac clutch on the compressor if that is you will have to get a new clutch kit from your local auto parts store to fix it
I had the same problem coming back from Hilton Head Island over July 4th weekend. I had been experiencing a grinding noise for sometime coming from the a/c compressor pulley. Aside from the noise, the a/c had been blowing strong, and cold with out any problems. Unfortunately I neglected it for too long, and it locked up after a terrible squeal, followed by a little smoke (belt burning). I cut off the belt, and was on my way. Granted it was a bit hot, but I was sure glad I was able to get home! I have found replacement a/c compressors w/clutch online from $200-$350 depending on condition (rebuilt vs new). I strongly recommend attending to the problem at the first sign of any noise.
the smoke is coming from the belt because a part has stopped turning ...you need to check which one it is... it could be the water pump...alternator ..a/c compressor...... power steering pump or the belt tensioner.... and your going to need a new belt
I'm guessing that you Expedition has been making this noise probably since you've had it? Even if it hasn't, I think I can bring you some comfort. If you could pinpoint where the noise was coming from under the hood, would you say that it's somewhere over on the passenger side? My dad owns a 1998 Ford Eddie Bauer Expedition, and we noticed a loud noise with the same habits as what you're describing. Come to find out, there is an air compressor under the hood, I can't remember exactly what it's for, but the sound that I believe you're hearing is the compressor filling up with air and then shutting off once the proper amount of pressure is reached. You might try popping the hood to try to locate the exact place that it's coming from, but I can tell you that it's probably a 99% chance that when you find your noise, you'll find the compressor I'm referring to. Hope this proves to solve your issue and helps to ease your worries. Have a wonderful evening!
It would make sense that it is suspension related as it does not make noise at idle but going down the road it does. I would lean towards it being a bad wheel bearing. Does it sound like it's coming from one side or the other? Also how many miles on the car? Does it get louder when the wheels are turning?
You can check the bearing easily by jacking up that wheel and moving it side to side and up down checking for play, a little bit of play is normal.
