I have an 01 Ram and had water leaking onto the passenger floor well last year. I added 1/2" hose to the AC drain line and it fixed it until a few weeks ago. Now the water seems to be draining back into the cabin even with the fix. There is enough that it is coming out the floor vents, and if I take a hard left turn I can hear it slosh over the blower. Any ideas about how to drain this? It's starting to stink. I live in central GA, so humidity will always be a problem, I can't wait for it to dry out

I have considered just dropping the blend door actuator servo to drain it, but that would a) make more of a mess and b) only work for a little before it was back to being this way.

 

Verify that your drain isn't plugged..... some crap makes it down that far, and it really doesn't take much to plug the hole.

 

@HeyYou, thank you, I didn't think it would clog after the mod for some reason, but it did. I put an adapter on my shop vac (I couldn't get a 1.5' long rod up the new drain hose) and sucked it out. I got just under a gallon of water and a fistful of dirt and leaves out. I will update if it doesn't stay fixed.

 

Wonder if you can spray some variety of disinfectant thru the system to kill any mold/mildew that may have cropped up.

That's a LOT of water.....

 

If anyone has taken apart the hvac box, You will be amazed at how much crap is in the bottom. It gets caught at the bottom of the evaporator coil but some still gets threw. I check the cowl area for any debris on a regular basis to keep it from getting in(especially in the fall).

 

I have an 06 Sequoia that began to get the Toyota AC funk and was able to neutralize it with a can of spray concrobium, I'll try that in the next few days here to keep it from stinking up the car. There was so much water before I drained it that it (seemed) to be containing the mildew to itself instead of smelling things up (the water reeked on my hand after I touched it), but now that it's gone who knows what is exposed *shudders*

 

spray concrobium?? What's that??

 

It's a heavy duty mold/mildewcide. I was introduced to eliminating some bad mold in the walls of my old house in OK after I found some shoddy foundation work that let water straight into the drywall It's odorless, generally safe around people, and leaves a fine coating that prevents new growth afterwards. I'm a wholehearted believer in it. This is it at Walmart: https://www.walmart.com/ip/652722114

 

Ok. Interesting. Thanks for the link.

 

Can try this also.
