What happens when drive rollers on power window break?
The driven gear attaches to the regulator-drive gear, often using drive rollers. These rollers allow for any slight misalignment, smooth window travel and quite power window operation. The rollers can also become brittle and break. When the drive rollers break, the motor will run, but the window will not go up or down.
What causes the power window to rotate and lower?
Both leads may show continuity to ground, depending on the design of the switch. Pressing the switch to lower a power window, directs current to one wire and grounds the other wire. Direct current flow in this position causes the motor to rotate and lower the power window.
What should the voltage be on a power window motor?
For example, voltage at the motor side of the connector may read 11 volts, with the switch turned to on. If system voltage is 12 volts, we have resistance in the circuit. This may cause the motor to run slowly or not at all. High resistance can also cause repeat motor failures. We test for a voltage drop by back probing across the suspected source.
