Gang:

I have searched the archives high and low but have found nothing.

My AC smells terrible. Not just kinda bad but gag you bad. Moldy and musty. Any suggestions and or solutions?

Thanks

 

put it on the fresh air mode. Its the one that looks like the air is coming in from outside.

 

I had the same exact issue on one of my cars. It is not a Porsche buy a Nissan X-Terra. Dont laugh i's a cool little SUV to use on bad weather days, Home Depot runs etc... The prob was that the return line from the condenser had fallen out of its bracket that holds the line straight and thus not kinking or drooping. Well the bracket broke or something due to extreme off roading I was doing. The return line due to its nature carries a lot of water in it from the condenser to resupply the A/C system. My line started to droop and ended up looking like a "U" from all the weight of the water sitting in the bottom of the U shape. The water starts to stink after only a little while and this is what you are smelling. Its funny cuz I guess I got used to it, but when someone else got in the car they were like wth!! is that nasty smell, then they would get a slight headache. All A/C systems operate on the same principles so I bet that is your prob. I was able to fix mine due to I found the line where it ran in the passenger foot well, someone on here I am sure could tell you where the A/C plumbing on your car is. Good Luck.

 

Take a bath

 

Tim,
do the following:

close all the window & turn on the AC MAX all the way to HOT let the car run for 15~20 mins. it might solve the problem. give it a try. won't hurt anything.

 

20C4S: Kind of dry it out huh?

I will take a shower then try 20's solution

Tommy: That makes sense. It smells like stale water.

 

Tim,
Take a look at this post from renntech A/C Smell

Thanks guys. Will try these things.

 

GM and Chrysler dealers sell a big aerosol can of disinfectant to spray in the A/C air intake with the fan running. Of course you'll need to temporarily remove the A/C inlet air filter. On older cars I've had luck just flushing out with a water hose, sometimes with a little dilute bleach water at first. You need to make sure the water drains out under the car freely first. The problem is mold and bacteria growing in the dirt and debris that collects in the air plenum under the evaporator coils. You can either kill the mold with disinfectant or flush out the mud with water.
