Power Window Operating Current Check
- Remove the power window fuse and connect an ammeter as shown, see Fig 1 .
- When the power window switch is pressed to the UP position, a large amount of current flows at the time the window starts to close and when it is fully closed, so measure the operation current in the interval between these 2 points. Standard value A) 4-6 Amps, [power supply voltage 14-15 volts at 25°C (77°F)].
- If the operation current is outside the standard value, see MULTIPLEX CONTROL SYSTEMS article.
