Good Evening Folks;
Now I have my son's 240 purring again, when you fix one thing there is always another. My daughter Lindsay's '92 740 has an inoperative heater blower. No blow at all, at any speed. I powered up the blower direct from a 12V source, it is fine. I checked the fuses for meltdown per the FAQ's, they appear to be good. The switch was acting up when I bought the car back in September, and I changed it. This time I put the old one back in. No change. So that leaves the resistor assembly that lives in the heater box. I have a new one on the way, but I am curious if I have overlooked something. The car has the late model 5 speed blower and solid state resistor assembly if that makes any difference.
Best Regards to all;
