Is there about 12 volts at the motor terminals going up or down?
A high resistance in one side of the switch contacts will drop the voltage too low to lift the glass.
Maybe the 'up' contacts are burnt?
The switches do come apart and the contact points can be filed and burnished to improve contact. A drop of Deoxit on the contacts may preserve them.
