2001 Ford Taurus water collecting in engine compartment

2001 Ford Taurus mileage: 70,000. There is a problem with water collecting in an area of the engine, which I'm told by the dealer/mechanic, is water build up from the air-conditioning. They removed it once but the cost was outrageous. Many of the independent mechanics in the area cannot remove it so I am at the mercy of the Ford dealer to have the water removed since it is apparently some "big secret" to keep me coming back and putting their kids through college via my repair bills. In the meantime, the water keeps sloshing around in the engine. I can probably remove it myself or advise an independent mechanic if I knew where the water was collected and/or coming from. Any ideas, other than staying away from Fords all together?
