2009 ac leak

I have been dealing with this issue and am hoping someone else may have run into it. When I run my ac for an hour or longer it starts to leak water out first on the passenger side right under the ac and if I run it for two hours or more it comes out on the drivers side through the center console. So far I have tried clearing the ac drain line myself and having the dealership clear the line no go. It dumps out when I turn sharply and then I end up with. A huge puddle on either side iI have just been putting baking soda in cups to draw out the moisture after running the ac but this is getting annoying real fast. So should I just rip up the carpet when it finally becomes mildewy and deal or does anyone else have any ideas since it does not appear to be a drain line clog. Thanks

what did you do to clear the drain? what did the dealership do to clear the drain?

simply blowing compressed air into the drain will only push the blockage further into the hvac box, even though a bunch of water is coming out, and will eventually make its way back to drain hole to plug up again.

what you or the dealership needs to do is to run an a/c snake through the drain tube to try to pull the blockage out.

to prevent something like this again, set recirc to outside air, turn off the a/c but keep the blower on when you know you're close to your destination. this will help dry out the moisture from the evaporator to keep it from molding/mildewing. the mold/mildew is what is clogging the drain after enough of it breaks off and plugs up the drain.
