Okay, I filed the pins a little bit and used acid flux paste and tinned the pins so that they are shiny. It is the input connector on the tailgate module (has RT/GE and RT/VI power in).


I stuck a wire into each of the pins on the female plug and scraped away.



I measured the voltage on both the white and black output plugs across MOT+ and MOT-. Both measure about 2.4VDC. I also measure 12VDC on both the white and black output plugs on the HALL_12V pin (GE on one, GE/SW on the other).


So the module looks okay. I can't prove that it's okay, but the output for both left and right sides match.


Then, I measured the spindles themselves. Measuring the resistance across MOT+ (GE/RT) and MOT- (GE/BR) came out to 2 ohms. Measuring the resistance across MOT+ (BL/RT) and MOT- (BL/BR) came out to 29.5 ohms.


So clearly, one motor is different than the other motor. Here are the two critical questions:


a) Which ohm reading indicates a broken motor, the 2 ohm or the 29.5 ohm?


b) Which color pair of wires is left, and which is right? In other words, is GE/RT & GE/BR the left side or the right side?


I figure I can answer b) by taking one of the spindles out and looking at the colors of the wires.


a) is the real critical question, because it can save me $250 to buy the correct side.


Thanks in advance!
