Your overheating window relay indicates either a failing relay or an excessive draw by one or both of the window motors. These relays can get warm but should not be HOT.
As always check all connections and terminals at the relay and the motors for tightness and corrosion as an increased circuit resistance can cause the same condition.
My windows were binding in their tracks and causing the motors to strain, a good lubing of the tracks and the regulator solved the issue and made them run faster!
