Normal Operation

During normal operation, when the window control switch is pressed to the second detent position to request a one-touch up or down operation, the window control switch provides a 12-volt signal on both the up and down line simultaneously. During a one-touch up or down request, the window motor determines intended window direction by the signal first received (first detent position). If the window control switch is pressed too quickly to the second detent position (less than 5 milliseconds of time between first detent signal and second detent signal), the window motor will not be able to determine the intended direction request and will not operate until the window control switch is released and pressed again.

This pinpoint test is intended to diagnose the following: 

• Power window motor not initialized
• Window control switch
• Window regulator motor
