It is very difficult to pinpoint the source of a noise by just moving your head around in the engine compartment. And I sure wouldn't risk my money on the opinion of a typical unskilled, minimum wage worker at most oil change places. These people are not mechanics; and they are not experienced at engine diagnosis. The method used by professional mechanics is much more precise and reliable. Just get a non metallic stick (like a wooden broom handle, or a length of stiff plastic pipe. Garden hose is not good for this, because it is too soft, and will absorb too much sound) While the motor is running, place one end of the stick so that it touches the alternator housing, and hold your ear against the other end of the stick. BE SURE TO HOLD THE STICK OR PIPE SO THAT IT CANNOT GET CAUGHT UP IN THE FAN BELT OR IN ANY MOVING OBJECT, SUCH AS A PULLEY! If you use a pipe instead; hold the lower end of the pipe just above the alternator, and press the upper end of the pipe to your ear. If the alternator is the source of the noise; it will be heard much louder through the stick when it touches the alternator. If the noise through the stick or pipe does not become louder when touching or next to the alternator; try moving around and touching the stick or pipe to other nearby objects, such as the water pump, the power steering pump, and the automatic transmission. The usual source for noises like you describe is a power steering pump which has run out of fluid.

thank you for the very informative reply. I recently called a mechanic and he wanted to hear it then would give me some ideas. So, today went to my mothers house to get the car and it doesn't start. Related? It tries to start but just doesn't. Lights and everything work engine just won't start. So now I need to tow it which will prolong a fix. I'm curious to know an opinion on this new problem cause if it's not related I can get it started so that the mechanic can actually hear it instead of fixing that first then the next.
Thank you all

There is a bracket that holds the alternator onto the engine, It is made of sheet
metal. It will and has cracked, When it does the alternator is not aligned to the
engine and the belt whines. The fix replace that bracket get it from a Pick your
part place it is held on by 13 or 14 mm bolts two or three as I recall.

I don't know whether you have already taken the car to the mechanic or not; but from the apparent hesitancy you've displayed toward personally implementing any of the suggestions posted here, it would seem that there would be a much greater delay if you struggled to get the car to start yourself; in comparison to the amount of time it would take a trained, experienced mechanic to fix the starting problem and also fix the source of the noise. There are innumerable reasons why the car might not start. In view of the complexity of sorting out the starting problem; it sounds like it would be far more appropriate, effective, and speedy to just let a mechanic deal with the whole thing.
If you post a question here; you're going to get as many different answers as there are people who feel like answering your question. And, since none of us are fortune tellers or wizards; there's no way for you to determine which answer you receive is the right one. It's all a crap shoot. Don't expect to receive a magic answer here which will eliminate the need for a commercial mechanic. It just doesn't work that way. And many mechanics will resent you coming in and telling them that you have a better idea than they do. The appropriate purpose for this forum is to offer suggestions to people who are working on their own vehicles, and need some additional direction; or people who have been dealing with a shop which can't figure out the source of a particular problem. But neither of those seem to be what's going on in your case. I'd like to suggest that the most effective way to work with the people who answer your question here is to give them feedback by trying their suggestions and reporting whether they worked or not. When you don't offer any feedback on what has already been suggested; it gives me the sense that you're not interested in methodically working the problem out; but are just hoping to receive a magic answer that suddenly turns on a bright light and cuts through all the uncertainty. But that's not what it's like to repair automobiles in the real world. We professionals (and also the good amateurs) usually can only learn about the nature of a problem from repeated trial and error. And sometimes that can be very time consuming and frustrating. There's no free lunch in the world; not there, and not here either.
But, that said; if I had to guess about the one issue which would create both the noise and would eventually keep the car from starting; my guess would be that the timing belt has jumped or become damaged. But I sure wouldn't bet my own time or money that it isn't anything else...

Jan 09, 2010 (8:52 am)
I am trying to replace my 1997 geo metro headlight but I just cant get the old one out. I remove the two screws I see that are holding it but it is still stuck in the corner somewhere. Anyone knows how to remove it?

If it's like my '91; I had the same problem.. What I found was that there are two "guides" underneath the light assemblies that you cannot see. They rust and are hard to pry out so.. what I did was to reach up and feel for the screw heads and remove them from the bottom.. They are directly under the front corners and are phillips head screws. Good luck..

Well... thanks I guess.
Anyway found it to be the AC compressor. Removed the belt and runs like a top. Will worry about replacing the compressor when the weather warms up.
Anyone know if you can "test" an AC compressor? Probably will get one from a junk/wrecking yard due to cost of a new/rebuilt one at the parts stores.

I agree with your plan to replace the compressor with one from a wrecking yard. The only test you can do in advance would be to spin the pulley, and see whether it turns freely. But that still wouldn't test what the compressor does when the A/C clutch is engaged. Nevertheless, most wrecking yards will stand behind their parts; by giving you another one if the one you originally buy does not work. It would be a good idea to confirm the warranty with the yard when you buy the replacement unit. It will also be necessary to refill the system with refrigerant when the compressor is changed. So this is a job for a shop to do.
