2005 Grand Cherokee A/C odor

Hello, I have a 2005 Grand Cherokee Laredo. 4.7L V8. I am experiencing a musty odor coming from my A/C vents when the air is on. We live in a pretty humid climate and I think the drain is clogged, but I cannot find the location of the hose to check it. Can anyone point me in the right direction. If you have any pictures,that would be great as well.

Try Turning the Vent on at a moderate temp, before you directly turn the A/C or Vehicle off. Condensation build up in the vents and starts to smell...

Just try to air out the Vents before you turn the car off.... try it!

There was a TSB out about this, I forget which one but its on WKJeeps.com. They stated that mold builds from the moisture around the A/C coil and this causes the odor. Dealer should take care of it

I checked the TSB and called a local dealer regarding it. They want 250.00 to perform the TSB. Should this be covered free of charge, or is that only if it a recall?

An AC expert once suggested spraying Lysol spary in the outside vent while the ac was running-several applications. I never tried it so I don't know if it will work.

The Lysol Spray worked for a few days, but it doesn't appear the A/C is draining underneath the car. Mymain concrn now is trying to make sure the drain isnot clogged.

Dealer will not pay for tsb only recalls also u probaly do have mold it will dry out and go dormant but to get rid of it all the way u will need to take it out manually try getting a borescope and checking through your vents
