Re: 2005 Pilot - Water under dash (condensation)

In the drain tube- have seen mud dobbers, wasp nest etc in drain tubes. All cars have one directly under evaporator- lok for evap pipes in and out of firewall under hood, then look directly below that for drain tube-- I've pull clog out before and got 2 gallons hitting the ground--use a pipe cleaner (remember grandpa had one- he smoked a pipe) to be safe

I was able to find the drain hose from under the car. Since I didn't have any pipe cleaners, I tried a tie strap but it didn't seem to be working so I tried a craft wire and I think it worked...The wire was damp although no water ran out but I think water that was there may have simply evaporated in the heat of the day because I was not driving the car for a couple of days ...I then drove the car with AC running for about an hour, When I got home, there was no moisture under the dash and the drain hose was dripping water.....Hopefully That fixed it.

Using a tie strap to clean out the drain hose helped for a while but the problem reoccurred...I then got an air tank and using a piece of fuel hose, cleaned the drain hose with air pressure....Its been dong fine since then.
