Passenger power window
Hello need help I got in my 05 LS today put the windows down and the passenger front window went up half way and stopped . I used the drivers door switch and passenger door switch waited couple minutes went up a little more , waited couple more minutes and closed fully . Came back to the car an hour later lowered all the way down and went back up fine ?? Tried it 7 or 8 more times worked perfect , any idea what’s going on here ? Please

This maybe a long shot, but I will ask anyway... How old is your battery? Does this happen only if the car sit idle for several hours (i.e. problem goes away after running the engine for a bit)?

Corroded electrical paths can degrade voltage level delivered to the window motor. This combined with a slightly lowered voltage source can create intermittent failure until a fully-charged voltage source is restored. The corrosion can occur in any of the electrical connectors. You had mentioned that you tried using the driver-side switch and the passenger-side switch with the same result, so we can safety eliminate the switches as being the problem.

It's the motor. I have the same issue but only when the weather is hot.
I recently had my lock actuator replaced on the door and the tech confirmed the motor's performance is degrading. I also thought it was the modulator, and I bought but never installed it, so I am out about $80 for that...
