Jeez! You would think that Volvo had it figured out so that iddy biddy animals couldn't get into the heater to curl up and die. I had this happen in my VW van and it took 2 years for the smell to leave. So I don't know how this happened, but it did. The 93 240 was outside for about a week. When I opened the door yesterday, a reeking stink greeted me. I recognized it from my nightmare with the van. Is there any fairly easy way to take covers or whatever off to get at the heater ducting so I can scrape the dead body away? Or am I facing 2 years of foul rotten stench? Where do these little beasties get into the venilation system anyway? Is there a hole somewhere that I should plug up? Surely some others among you of this list have been cursed with the same calamity! HELP! Any suggestions for a truly effective air freshener would also be more than welcome!
