76 911S power window problem
 

My daughter and I have recently started to work on my 76 911S together. But we are having trouble fixing the driver side power window. we have replaced all broken fuses and checked the wiring , but still the window will not roll up. I was wondering if you had any suggestion on how i could make this window work, with out taking it in to a shop , since i would like to use the car as a good learning experince for her and bonding time for me. please let me know if you have suggestions or are having the same problem.
