How to replace an ac condenser on a 97 cavelier

the only other item that should be replaced is the filter/ accumulator item next to the condenser

You have lost the charge and that is commonly due to a couple of built in problems, these are, the AC line "O" rings leak after they harden up from heat and then on top of that the AC condenser leaks due to vibration, the condenser core will pass a vacuum test but it will be defective, so replace all the AC line "O" rings with the new design and replace the AC condenser core. A special tool is required to release the lines to service the "O" rings and any parts store will have the kit. I did hundreds of these at my Ford dealer

Do the valves move?

If its real water, it could be condensation which is normal, especially if the air temp is cool and damp.
If its actually coolant, its probably a leaking head gasket.

Well thinking about the problem there e a flap in the vent pipes to shut off theatre and ac unit perhaps something has got in the pipe and stopping it closing or perhaps your heater control is US and needs replaceing . ( but I take it you have turned your heater to cold )

Where is the condensate drain on a 97 safari and how do i clean it out

The drain tube for the evaporator case is plugged with various debris which allows the normal accumulation of condensed water to overflow the case onto the floorboard. Run a brush or similar tool into the tube which should immediately drain the cavity. If you catch the water in a pan, inspect it for debris. This should work ok for a year or so, then re-clean the drain as needed. The more the AC is run, the more debris will accumulate. Hope this helps!

no. the lines for your cavalier are the same from the late 80s to present day. they are all interchangable.

I just had my AC condenser pump realigned for the same belt noise issue. They also discovered the bolts holding the condenser in place were stripped out from the previous owner. I now have no belt noises! I had replaced the idler and bearing and have been through 3 belts before we figured this out!
