Had the passenger door card off this morning, reset button depressed, window down, little wait, reset released, rest pushed, all the way up, little wait, reset released. Tried the door, auto drop worked like a charm about 10 times (thorough testing). Door card back together, another round of testing, all great.
Hour later I go for a drive, check passenger door auto drop when I park, not working, grrrrrrrr. The glass doesn't collide with the frame, so no damage, but it should work and its getting to me.
Could it be whatever tells the door it's open, not working? If so, where is this "sensor"?
Could it be the glass isn't sitting straight? it looks spot on to the door frame when it's closed, but the scraches stop about 5mm above the waterline when the window is fully up?
Any other ideas at all welcome. Thanks.
