2000 Rx300 Driver And Front Passenger Window Problem

[Mystery123]

I read the threads about cleaning switches and other solutions but mine acts little differently.
I bought this RX300 in 2007 and the previous owner mentioned about the front windows sometimes acting up.
Now 8 years later, it still has that issue.
Driver side is not that bad but passenger side window always gets stuck on the open position if I lower it and won't come back up as long as I drive the car.
The funny thing is, if I stop for few minutes, turn off the engine and start it back up, I can pull the window up easily and it goes all the way up smoothly and quickly but if I lower it again, it is stuck again.
If I stop it in the middle while going up, it sometimes acts up and need to lower it again before I can close the window.
When it works, it works fine and smooth.
And it always goes down without any complain.

As far as I remember, both buttons (driver and passenger side) behave the same way.

Rear two windows don't have any problem.
So what's happening? What to check?

Thanks

If there are no error codes, this might be a wire problem (I had the latter one on one of my previous Toyota's)
