Bits of ice shoot from center vents...

[Wirewizz]

I searched through past threads, but couldn't find any answers. I think my evaporator develops ice inside as I drive the car with the air conditioner on. I live in SoCal. I've noticed fog blowing out at one point, so I turned the fan to max and little bits of ice shot out (only through the center vents). I also have noticed an excessive amount of condensation under car (probably about 2-3 cups at times) after I park. This does not happen consistantly, but often. Do I need to worry? My brother tells me that there might be a sensor which keeps this from happening. Please let me know...

I think you are fine. Humidity goes up, so does the foggyness iside the cabin and dampness.

Does not sound like anything to be to concerned about you might have your system presures checked you might be a little low on freon.

Cool. Your NSX has a weather-maschine inside as it's snowing inside your NSX. :tongue:

My 91 does the same thing. I was worried at first because when i set it to "full auto" at a normal 70 degree or so temp the vents barely blow at all but the air is cold as could be. When i switch it to manual and crank it all the way up then i get the same fog/ ice that you are experiencing.

Ive been told that this is some what normal.

I also have a LOT of water under my car when i have been running the ac for awhile.

maybe Brian can rig up a syrup dispenser in one of the vents,then snow cones baby!!!:tongue:

There is a temp sensor in the evaporator to prevent it from icing up. It cuts the compressor when temps are at freezing. It could be out or perhaps it's just off a little? Have you run the self-diagnostics?

:biggrin: I think at this point you should start taking bets with your buddies on who has the better A/C, and make some money.

Thanks for the tips and funny additions. My car is at the stereo shop getting the Kenwood 8120 installed so I can't trouble shoot right now. I know that I'm probably a little low on freon since I can see bubbles in the little window. Do you think that could cause the freezing? I think I'll recharge the system and see if it helps. I'll post pics on stereo install later on SoCal...
