Hi TB Gurus,
I've been looking over the forum, here, there and everywhere and can't find what I'm looking for.
I suspect my blower motor is failing, causing extra draw, causing resistor to fail. Wires are discolored but not melted (yet). I've got a 2005 TB EXT, LS with dual temp climate control (the expensive resistor). I want to know what the specs for current draw at the different speed settings. I know I have to replace the resistor, but I don't want to buy a motor 'just because' and hope that fixes it. (I'm on my 3rd or 4th resistor since buying it in 2012) If that doesn't resolve it, I've just wasted $200. Can someone tell me the amp draw I should expect?
Thanks in advance,
Farmall Dude

Thanks 16vcabman.
I have been using the knock-off resistors, which is why I didn't think about the motor until after the 4th or so one.
Maybe I'll bite the bullet and buy the OEM...
