Hi i have a 03 Trailblazer EXT and recently my drivers side front window just stopped working. I took the door panel off and looked at the cables and seen that the cables were beginning to fall apart. I figured okay i just need a new power window assembly. I looked online and order the window regulator. As i was installing the new regulator i realized that the regulator was different from my original one. The new regulator only had one cable attached to the motor and my old one had two cables. I returned the part and now i am helplessly trying to figure out why i cant find the correct window regulator for my car. Can anyone tell me the right part number for my regulator. PepBoys said that i needed a Dorman 741-690 but thats the last one that i ordered and didnt fit. My vin is 1GNES16SX32167115. Sorry for the long post but i dont know how else to explain my situation. I just dont understand why GM makes it so hard for us to find the right parts.
