searched everywhere including the faq section the fan i have is part number f3le-8146-ac cant find out if its two speed or not anywhere i hooked up the fan to a battery and the center and bottom term worked the fan same speed so i think i have a single speed one can anyone confim this fan one or two speed
(took blade off and found another number on motor f3lh-8k621-aa ) cant find this one either please help

Single speed fan should have 2 wires, 2 speed should have 3,
unless it uses ballast resistors to control the speed.
There are 4 wire variations as well.

i have a mk viii and it's single speed although there are 3 wires. on mine there were 2 blacks and 1 blue but a black and the blue are actually the same (shorted internally) - don't ask me what's the logic behind that, i have no idea. there is a resistive load on the vehicle that makes the slow speed and is installed in series on one of the wires.

by common sense you would think that's the way it should be, not the case with the mk viii
EDIT: just noticed you mentioned the resistors - that's what they use on this one and seems to be the case on the Taurus dual fan as well (some have resistors on the fan shroud)
