Acura Integra Ac Problem?
I have a Integra the ac was ice cold and couple weeks ago driving to Sac noticed that the ac water stuff is leaking on the inside of my car on the passenger side under the glove box area and now my ac isnt blowing cold anymore.. What does this mean.?
leaking water into floorboards means your evaporator drain is plugged or the case is cracked and not draining under the vehicle. That should not cause it to stop cooling. You have another problem also.
What Gunmetal_B20_Hatch said, the only, "ac water stuff" would be condensation off the evaporator and as mentioned it can only mean a plugged drain, also as mentioned it would have no effect on cooling.
Are you sure it is H2O, and not coolant, [antifreeze].
If the evaporator was leaking, you would never see the refrigerant, [R134a] it is a liquid only at 50PSI or more, less then that and it evaporates, [pretty much instantly], what would be left behind is the oil, either PAG or Ester oil, but it does not resemble water, it is a thin oil.
Start the car, turn on the A/C and see if the compressor is working, [A/C compressor clutch engaged]. 94

@ Gunmetal ..So would I need to take my car to a shop to get it unplugged and fixed or could I do it myself? And Yeah I realize my car is a 94 and it obviously does have a couple issues thanks fcm
Did you check to see if the A/C compressor is turning on?
In most cases you can unplug the drain by running a wire up into it to unclog it, if that does not work the evaporator housing must be removed, that can not be done without recovering the refrigerant.
Even with a plugged evap drain the A/C still would work, that is why you need to see if the compressor is turning on, if not you may have a leak and no refrigerant in the system, or not enough refrigerant for the system to work, there is a pressure switch on the A/C system, that prevents the A/C compressor from turning on if pressure is too low or too high.
If the A/C compressor is not turning on, check for pressure in the system the same way you would a tire, press the shrader valve in one of the AC service ports.
If the system is empty, you can remove the evap. housing yourself and clean the drain, you will need to disconnect the A/C lines going to the evaporator, then it is just a few bolts and screws to remove the evap and case from behind the glove box, open the case and clean out the drain.
At the same time you can inspect the evaporator for leaks.
Once the drain is cleared and the evaporator is checked it can be reinstalled, new O rings should be used at the A/C line connections.
You will then need to go to an A/C shop so they can check for leaks, [nitrogin pressure test] and fix any they find and then recharge the system. 94
