My car's driver side power window isn't working. What is wrong and how can I fix it?

I’ve bought Dorman replacement regulator/motor assemblies on line. The two I bought fit easily and worked well. I’m sure it’s less than $100 for the assembly.

@Ottomotive117, unbolt the window from the regulator and push it out of the way. Then try to operate the power window. If it works, the window is binding and you need to lubricate the window channels. If not, it will be either the switch or the motor. Unfortunately, you have to buy the switch console. Given that the car is 16 years old, it could be either.
