My girlfriend's 89 Sable has a problem: The blower for the heater works only on the "high" setting. It blows out very nice, hot air then, but absolutely nothing on any lower settings. Any help or suggestions would be appreciated. Thanks.
Sounds like it could be your fan switch. The fan switch is what's right behind the knob you use to adjust the speed with. I'd go to a bone yard to find a replacement off a crash of if you want to pay top dollar go to a dealer. Though Autozone will have a replacement for you.
