I have a 2008 VW Rabbit that we have owned since new. Suddenly, without any obvious reason, the HVAC system is emitting a smell. My wife calls it a "band aid" smell, of adhesives. I smell it mostly on startup, but my nose is terrible; to her and my daughter, it is apparently horrible. The AC drain is draining. I used nextzett Klima-Cleaner to clean the evaporator, although it looked clean. That didn't help much, if at all. Not really sure where to go from here, in 30 years of auto maintenance I have never had to deal with this. Any ideas? Thanks!
