Lesabre rear windows

You described a classic symptom of a broken window regulator, a common issue.

Thanks, I'll check it out.

I don't know model year? if you have power window circuit breaker, feel of it when problem is ongoing. If breaker gets hot, it'll trip and none of windows will work until the breaker cools down and resets. I have removed window motors, used jumper wires to battery, the motor would run a little bit and stop, run a little bit and stop. At least on that vehicle, a new window motor fixed it. There could be other issues? good luck
