...is in turn pulling more voltage than the speed-reducing resistor can handle, overheating it, and causing it to fail. Enough of this will fry the resistor. Many here have simply replaced the resistor, but my guess is that this in turn will fail for the same reasons, sooner rather than later. Those who've tried the transistor replacement can weigh in on how lasting the repairs are.
To fully resolve the issue, you need a new blower motor (and heater core while you're there to save duplicating the effort when that goes later). This is a big job, but doable yourself. Search past postings on heater core replacement for many good writeups!
