Right after I bought my XK8 I noticed a pretty foul smell when the a/c was on. I searched high and low for the cause. Cleaned the drip vent, which didn't need it. Cleaned vents at base of windshield. Opened the dash to get at the diffuser box. Couldn't find any reason for the stink. But the odor was bad enough to keep me from using the a/c unless it was raining. On a chance I bought a can of air conditioner duct cleaner from AutoZone. Shot half of the can into the vents at base of windshield and the rest directly into the cabin air intake under the dash on the passenger side. Immediately I was sorry I did. The perfumey smell was worse than the stink. For the next day or so I had to drive with the windows open. And then ... like magic ... all the smells disappeared. I could not have been happier. There was absolutely no smell even when the a/c was on high. That was about a year ago. Yesterday I noticed just a hint of a watery smell returning, so I stopped by AutoZone and bought the last can they had in stock (being sort of a seasonal item there was none on the rack, but the clerk found it in the back). If you've been plagued by a similar stink, give it a try. Comes in a skinny green and white can with a short nozzle for directing the spray. The manufacturer is IDQ and the name on the can is A/C & Heater Duct Cleaner. $7.99 and worth every cent. Someday maybe I'll find the cause of the smell, but for now this'll do.

 

Thanks for the heads up on the product. Sounds like a good quick fix.

Here's an older post that may get to the source of the problem.

Thanks. I read that thread and every other I could find when I was battling the stank. I opened the dash, hoping to find the gunk shown. Nope. Mine was clean and dry and the foam all intact. I was really frustrated and was about to turn to professional help when I tried this product just for the hell of it. I honestly didn't expect it to work, but I was desperate. I've come across very few products in my life that I could recommend unreservedly. This is one.
