Heater Blower Issue '78 300D
Hello! Let me say that I have learned more from these boards that I could ever imagine.
My daily driver, 78 300D just developed a fairly weird issue: The Lo and Hi fan speeds stopped working. Note: the defrost mode works well, fan blows hard and hot. I am very versed in this car, I have had few electrical problems and few vacuum problems, but obviously, I have a problem now!
I'm going to tear into it this evening and start looking for the issue and I'm sure I'll track it down, but anything in particular that I should be looking for first?
Thanks in advance! Erik
