I have a code for a window limit switch on the Lt. door I understand the switch is in the motor and assume it must tell the computer the direction of rotation and revolutions. “I know what happens when you assume” Anyway how can I test the motor or sensor in the motor and see if it is working correctly or not. I was thinking of using a multi channel scope to see what I could see but I am still not sure how this switch can tell the computer the window is up or down. Second I know this code will keep the top from going all the way up because it thinks the window is still up. Will it also keep the unlock mechanism in the windshield post for unlocking? Also when you open and close the same door the window will not lower its self like it should
