Mine appears to try to stay moving as long as the switch is pushed also. However, on 123s there is a Power Window Relay behind the Instrument Cluster. Perhaps some Relays are more sensative than others and will cutoff the current to the Motors.

I have not read of anyone replacing a Power Window Relay or what type of trouble they cause when they go bad? Does anyone know?
