Question Several maintenance questions LS430 ?

1) Why does my drivers window switch suddenly get a bur under its saddle? It will suddenly refuse to move the window more than an inch and then stop. Wait a few min and it will again move another inch. But if I pull over and recycle the ignition, it will return to normal operation.

2) Is the rear window heater removable and replaceable? It looks like an after market heater that was just glued to the surface and not a heater in the glass as I would have expected of Lexus. It still works but the edges are curled up.

3) How do I clear the Maintenance Required message after I change the oil? I went to the maintenance screen on the GPS and selected the choice that put all the maintenance items on the screen. Only the oil mileage one was activated. I set the mileage to 5000 and the red triangle has not reset. The mileage is counting down as I would expect but the warning has not cleared. What is meant by the "ON" and "OFF" selection on the upper right corner of that screen. It doesnt make sense either way.
