I just took apart a rear heater, and found out that the only thing that makes a motor a two-speed motor is a resistor(DUH!). So... the ceramic ballast resistor could be used to make my heater(front) motor blow on two speeds, right? Wire low speed through the resistor and high bypasses the resistor, eh?  o I need to use the bulky ceramic type ballast resistor, like used on the points or is ther another smaller more compact resistor like Toyo uses on the heater motor? I guess that's an obvious question with an obvious answer, but what do I ask for like at an electronics shop? Any Sparky's out there? Thanks, I'm a newbie to this board. Still use CCOT, that's where I learned a lot. Pin Head???
