As mentioned, here's the video on retrofitting the Volvo 850 blower motor into the 240D.

Works like a charm, by the way.


After reading, Googling, and thinking last night, I believe my low-speed problem is due to a bad resistor. Unfortunately, that part seems to be very expensive and hard to find.

So, either I'm going to try to come up with something on my own to mimic the factory part, or I'll run a separate fused switch to run the fan at high speed when I want to.
