Turning on the heat in a W114....
I have more problems. In my 1973 280C, I have tried to turn on the heat using the fan speed control alone. However, the fan will only turn on when I ALSO turn the "Colder" switch. At that point, the blower speed will be able to be changed by the appropriate knob. Is this normal?
The blow-by is quite warm, but when I use the "colder" switch to turn the blower fan on, it will not blow warm air at all, no matter the settings I use on the four slide controls.
Is the above the proper method of using the HVAC, or should the fan be able to be turned on from just the speed control switch alone?
