Window is stuck in down position?

I checked all the simple stuff like fuses and safety lockout (window is stuck in down position) and I have removed door panel and it seems switch is still working but motor may be faulty or maybe it's off track? I'm not 100% sure and before I do anything I want to confirm so don't screw anything up so when I press switch the motor runs for a split second in either direction and stops, but this doesn't move the window at all it just seems to move the wire in and out slightly then stops completely, I tried assisting the motor by gently lifting while pressing switch but it didn't work and if I manually push window up to close (it's been raining a lot here) it just goes back down I can't seem to have it lock once it's fully up/closed, any help would be greatly appreciated and would love to find a fix that isn't just go buy this and this and that (if that's what must be done I understand and will do it just was hoping for alternative suggestions first if at all possible but again if it's an impossible ask don't hesitate to tell me so as I want this fixed asap but just didn't want to be charged an arm and a leg for such a simple problem, I hope that is.) Thanks very much for taking time to read and assist as this is time sensitive and can't tell you how much any help is appreciated! -Rick from PHX, AZ.
