Recently completed the blower motor and resistor replacement on the 91 318i. Somehow I dislodged the male spade ground terminal when I installed the black plastic cover the first attempt -- didn't make that mistake this time. This thread was a big help and it's nice having working AC prior to the onset of another Vegas summer.
Regarding getting the motor installed in a proper orientation, I used a Sharpie to draw a marker line on the old motor casing just above the resistor prior to removing the motor. From the seam on the motor case, measured the distance and drew a second line on the replacement motor before installing it.
Once again, thanks. This is an example of a thread that keeps on giving.
