1994 Mazda B2300, 212,000 miles, 4 cyl. Manual trans. During the winter, I had the heat on & black smoke came from my vents. I stopped & unplugged the blower motor. I checked the motor with 12vdc & it works. I didn't see the condesation people talk about when the heater core goes. It was a really smelly black smoke. Any ideas?
