Power window called in sick

2006 Access TRD SR5 and the passenger window "worked" when I bought it and then died shortly after I got it home. I say "worked" because it was noticeably sluggish and intermittent in speed and doing a kind of slow motion jerk on the way up. It got there and closed but it was clearly dying. Now it's dead. I assume the switch is okay because power got to it, is that safe to assume? So it's the motor? Tips? Tests? Tricks?

I love this thing but it's new to me and I'm winging it here. Thanks for all goodwill and help.

 

Make sure the child lock isn't engaged on the driver controls.

 

Ha. My face is Radiant Red like the truck, Andy, and my learning curve is obviously straight up. I have much to learn here. Thank you kindly.

(It's back to the slow motion jerk on the way up. But it works.)

 

Been there done that.

Spray some lube on the side of the window frame, where the glass slides up and down, that may be all it needs

 

I'll pick up some silicone lubricant and give it a shot. Literally.
Thanks.
