With car running press the rear window defroster (coupe), button lights up, after some minutes of driving, the rear window remains unheated. The button light stays lit until i manually push it again.

after you check everything above, carefully check for current at the grid itself where it is connected at the window. sometimes the grid is damaged and the circuit is broken. once i repaired a connection by painting the lines with a conductive paint made for this purpose. look carefully and see if there are any slight scratches through the grid lines at the connection points.
