check the voltage at the window motor. you can use a test light between the 2 conductors. if it is good there then suspect the motor. i know that older motors could have a built in thermal protection. if the motor got stuck on it would kick a thermal circuit breaker and then reset when it cooled off. this kept the motor from getting hot and burning up. if you have a multimeter you can disconnect the motor and set the meter to ohms. it should read maybe .4 to about 6 ohms. if it shows infinite resistance then either the motor is burned out, brushes are not making contact with the armature or the thermal protector is open.
