a/c fan speed resistor on E12-based 635CSi

Post by thehackmechanic »

While on a trip this weekend, the blower fan for the a/c in my '79 Euro 635CSi (E12-based), which had been happily working on all speeds, began working only on high. The heater blower still works on variable speeds. Am I correct that the resistor pack that controls the a/c blower fan speed is inside the evaporator assembly? I'd retrofitted a/c into this car a few years ago, using everything from another Euro 635CSi, and I thought I'd photographed everything pretty well, but I can't seem to find a photo of where the resistor pack is.

Thanks.
