I have the 93 escort 1.9 and have been noticing an intermittent squealing noise from somewhere up front,but dont know where exactly.At first it woild make the noise while driving 40-50 miles an hour.The best way I can describe the noise is that it sound like a Trane home a/c compressor when it goes out on high limit.Its not all the time,but can start at ant time ans stops when I slow to a stop.It is starting to get a little worse.Can the esort repair gurus of the forum help me out?Thanks in advance,Harvey.:banghead:

I'm wondering-when it's stopped if you rev the engine will you hear it? When you are moving-if you put it in neutral and let off the gas will you still hear it?
Is it a manual transmission?

Ido not hear it when stopped and with revved engine.Ihear it even in neutral.When islow down to a stop,the sound goes away,and it is a standard transmission.

Have you ruled out the belt? That is the most common thing to start squealing. Otherwise you might want to take a bit of grease to the pulleys?

Your car has little bearings inside the two pulleys the serpentine belt runs around; the tensioner pulley and the idler pulley. You can buy new pulleys, they arent too expensive. The bearings wont last forever.
It could also be the bearing in the water pump, though its unusual for it to make a noise you would hear inside the car. If its the water pump, it will start to leak a little coolant before long I think. So if you car is using coolant - that might be it.
There are of course bearings inside the alternator, the p.s. pump, and the a.c. compressor. The one inside the p.s. pump lives in lubricant. The other two dont. If its one of these bearings, or the pulley bearings - you could remove the serpentine belt, and drive the car around the block. If the squeal is gone, you know its related to something the serpentine belt goes around, or a very worn serpentine belt itself. You just wouldnt have any power steering in this case, and the 'gen' light on the dashboard would be on. It wont hurt the car though.
Its possible for the spring inside the serpentine belt tensioner to go bad and crack - but its pretty rare. Bad bearings in those pulleys are more common.
And does it happen when you are NOT using the air conditioner? If it doesnt - it could be the a.c. compressor beginning to clog up with crud inside. Its called the 'black death' for a compressor.
And I like your description of the noise.
