I received an answer to above question but now I can't find the answer. My blower switch is stuck on high. I purchased a new resistor but it doesn't look anything like the old one.
OR i bought my blower motor resistor from Oreilly auto parts. it was a borg wagner resistor and Oreilly offers lifetime guarantee on the part and was a direct fit. so for ~$75, if it ever fails again, they replace it for free.
