Sweet smell from vents w/ac on?
I'm getting a sweet smell from my vents with the ac on. Normally I would think it's antifreeze but a friend told me freon has a similar smell? It goes away after driving for 10-15 mins. It's been doing this for a few days now but today at a light I saw a white steam/smoke coming from the vents? The truck is a 2001 Mazda B3000 Dual Sport w/96000 or so miles. I really don't want to jump in and change the heater core if that's not the problem, but I will if necesary. I've found a few writeups on how to change the core on a 98 ranger and assume it's the same as mine?
