MrMagoo Posted August 1, 2015 Report Share Posted August 1, 2015 Greetings, all: I just got a 1995 DeVille, 4.9-liter, 88k on it. I love almost everything about it, except in Econ mode, the vents put out a very strong, stinky smell. At first, it reminded me of tuna fish, but later I thought...hm...might be coolant. The Auto setting for A/C is just fine; the smell only happens in Econ mode. Now, I'm VERY new to doing anything on cars other than changing wiper blades, but I'm wondering if it's the heater core, from what I've read elsewhere. I haven't been able to find this specific thing happening to anybody else, and I've done a fair hour of Googling. Any help would be appreciated. Thanks!
