My pass window on my 2003 350z when closing goes up then comes back down what gives
Few ideas: I believe this car and most convertibles the windows drop slightly when opening and closing the doors and lowering the top to allow clearance. But both sides do it, and sometimes people dont always notice it. Some cars also do it when it senses an obstruction, generally fingers or lockbox on a dealer lot, but it will do it just from a collection of dust, resistance on the motor I believe. Anyway it did it on one of my cars and I had to take the door apart and clean and lube the window and wipe out the rubber and it stopped doing that. But cant rule out bad sensor or some other gremlin
