How to replace window drivers side motor on 2004 Kia Sorento

Can I justreplace the motor or the entire system,
motor stops but if I push the window down slightly it works again seemed like a flat spot on the motor armature.

sounds like your window regulator
if your motor stops making noise while operating, your motor is bad...if your motor does not stop making noise and you hit that flat spot, then your regulator is bad...either way, i would replace both so it will work for another eight more years!
TO ANSWER YOUR QUESTION, THIS IS A PRETTY INVOLVED REPAIR,THINK YOU SHOULD TAKE IT TO AN AUTO GLASS SHOP FOR THE WORK.
