Automatic Climate Control, thanks for that important bit. There are 2 types of blow motor
resistors. The one for manual controls is called blower resistor, if you bought that, there's
your problem. The one for auto controls is called Blower Motor Control Module, both look
the same but are very different. If indeed you did get correct one, make sure you replaced
the pigtails too. These are notorious for melting on the inside and shorting out, hard to tell
visually. I've replaced several of these, pigtails are a must. This problem is so common,
local autoparts might even have them. If not, rock auto .com has them for sure.
