I have a 1997 E320 and the fan only blows on low for either the AC or the heater. In a manual for a 1992 300E it says the fan is controlled by resistors mounted on the firewall behind the master cylinder. When I look on the firewall I find no housing behind the master cylinder. Does anyone know if 1) the fan is controlled by resistors and 2) where they are located?
Also, DOes anyone know when the shop manual will be released on CD for this car?
Thanks, Ken
