A5: Check Left & Right Window Switch Grounds

With the ignition key in the OFF position, disconnect left and right power window switch connectors. Measure resistance between Black wires (terminals No. 2A and 7A, left power window switch) (terminals No. 2B and 7B, right power window switch), at left and right power window switch connectors and ground. See Figure . Is each resistance less than 5 ohms? If yes, go to the next step. If no, service the Black wires in question.
