When I first start the car and roll down the windows every thing seems fine. When I go to roll up the right window it starts going up than stops. I can wait a few minutes and roll it up a little more before it stops again.

I was thinking it might be the ECB. But if that’s bad, wouldn’t I have to replace the entire motor because it is attached to the motor? Than again this could mean that the ECB is working just fine and that the motor itself is just building voltage because its getting old.

Any thoughts?

 

You can bypass the ECB, but you have to take the motor apart to do it. That probably won't fix an old motor, anyway. Easier to just change the motor (which is likely your problem).
