Used to have a 76 Dodge pickemup that I bought from a "real pro:glasses9:" one fall. Every time I turned the heater on, would get this funny hot smell. That first winter, I was on my way to work one morning, and saw smoke from the corner of my eye. Looked in that direction just in time to see the heater fan switch burst into flames. Wasted a whole cup of coffee puttin that out. Wondering why the fuse hadn't blown, I looked in the fuse block for the first time and found 4 fuses replaced with 1/4 inch threaded rod.:angry7:
