I noticed yesterday after running the AC on the way home from work that there was no puddle on my garage floor. I'm not sure if this could be just because the heat here is dry heat, but I don't want to find out by waiting for water to leak onto the floor in the car.
I always hear that you can blow out the evap drain tube with compressed air, but almost never any more detail than that. Blowing from underneath the car would be convenient, but it seems like that would just blow whatever's clogging it up into the assembly, and lead to worse clogs in the future. Is the "real" way actually to get at the drain hose from its source and blow the crud out rather than in? If so, how much of a PITA does that usually end up being?
