    my 01 1500HD is stuck in 4WL right now, and i think i have it narrowed down to the encoder motor. i've already replaced the switch and the next step according to everything i've read is to change this. the problem i'm running into is that there are two different part numbers that my truck might use, and i cant tell which one i have. there are no numbers on the part itself, and the dealership won't tell me the part number, only that they had one that will work. i was told to check the OEM numbers, but i have no idea where to find this info. any help would be appreciated. thanks in advance. -Garrett
