Passenger window rolls up and down on its own

Hi,

This is an interesting one if the window goes fully up and down on its own only when the top is open. Since it is moving, we know it isn't a power issue. That leaves the convertible top module, which should open the windows about 1/2 way to prevent damage when the top is opening.

Here is what I suggest: Since we are dealing with the convertible top control module, we really should scan the can-bus to see if there are codes stored.

CAN stands for controller area network. Basically, all modules/computers are tied together via a few wires. By scanning the CAN, it will retrieve codes regardless of the module storing them.

Here is a link showing how it's done:

If possible, try this and let me know if codes are retrieved and what they are.

Take care,

Joe
