When I first turn on the AC, it smells very musty and moldy, like a wet basement. This lasts for approx two to three minutes, then it goes away. I believe I have mold in system somewhere. Any practical advice on how to get rid of it. Can I do this myself? Where is the location of the AC motor, and what is the best way to clean it, etc...

Could I have caused the problem by having the AC running while using a drive through car wash?

My Durango is a 2002 RT.

Thank you in advance for any assistance you can provide me!

go to the grocery store and get a spray can of "clean linen scent" lysol (or something like that). turn on your vent and air will pull through the passenger side cowl. spray the lysol in the cowl for about 30 seconds or so and you'll see it getting sucked in.

My AC is stinky too, but it only happens when the rear ducts are turn on.

Is there a way to clean the rear ducts too? I think moisture is pooling somewhere in the back there.

The smell has to due from bacteria growing in the stale water.

I think the problem lies with the fact that the A/C evaporator drain is clogged. I'm having that issue right now. I can actually hear water sloshing around in the lower part of the dash, but can't find the drain. My durango is not leaving a wet spot on the ground after running the A/C.

The drain pokes through the firewall on the passenger side, about half way down. It is a small stub.

Any tips for my stinky rear AC?

The front smells just fine, it's just when I turn on the back it starts to stink for a few minutes

Sorry, that one I can't help with. I have not had to anything with my rear A/C, therefore, I do not know where the components are, the plumbing, etc. The online 2001 Dak manual doesn't help either. As I was looking in it and wondering why I can't find anything, I realized the Dak's don't have rear air (LOL)!

Thanks for tryingUnited1
