I own a 1995 Honda Accord EX Vtech 2.2L with 179,000 miles.

Over the last few weeks I've noticed mist coming from the air vents. When the windows are closed all the windows fog up QUICKLY. The only remedy is to turn the heat all the way up on "fresh air" mode and bake myself. There is also a lot of moisture in the mist on the windshield.

i can think of 2 things that may be causing your problem 1 is the heater core can leak inside the heater assembly and coolant will be blown through the vents 2 the ac drain can become blocked with debris like leaves and will cause the water to back up into the ac box , be careful since this water back up can harbor bacteria and can cause leagonairs desease, make sure the drain is clear , its a small tube on the passenger side fire wall just above where the feet rest . lysol in the ducts may help with smell and bacteria.... rick

No, no, no. I live in ATL GA, there hasn't been s need to use ac lately.

Actually, I just gor home, and noticed there is a little bit of coolant leaking out. Also, my wife says she smells something "funny" just before the mist starts coming out. Could this be coolant she smells?

Should be a drain on the p/s bottom of the firewall.

what you can do is straighten out a clothes hanger and attempt to push it into the end of the rubber drain nipple and try to dislodge the debris from the tube , what i like to do myself is to take a shop vac and attempt to suck the debris out of the nipple
