That could be a broken wire in the door jam or an actuator just just isn't strong enough. It depends if you can hear it trying when the door is closed.

It work's every once in awhile with door closed but mainly with it open but it doesn't work at all most of the time I can't figure out to remove the assembly that holds the speaker and window, regulator and motor.

I don't know why you would need to. You have an electrical problem that needs to be troubleshooted.

how would I test it with a multimeter I've never really used one?

This will require extensive electrical knowledge to follow a complicated wiring diagram. This is not something that you are going to learn how to do on the Internet, especially with an intermittent problem..

well I can't afford to pay the dealership thousands or someone hundreds that's why I try to do everything myself I've a lot of mechanical work in the past but not electrical

OK, here ya go

don't I have to take the whole assembly out to get to the actuator? Looks like I'll have to take out the window regulator assembly before I can remove it
