I have a 2006 Crossfire roadster and with the engine running the windows go down step by step as if something is switching the relay on and off every second or so so it takes a few minutes but left at idle the windows will drop by themselves. Bearing in mind I am not touching anything they are doing it themselves even when driving along.

If I press the window switch to put the windows up or down they work perfectly but if I put them all the way up they will work themselves back down again.

The roof light on the switch is flashing and the rear spoiler doesn't work.

If I operate the roof, it will after pressing the button a few times open but when closing it gets confused and gets stuck at the point the deck lid needs to close. The motor whirrs away but the lid doesn't close.

Now the interesting bit! With just the ignition on the roof works fine and the switch doesn't flash and the windows operate normally. The whole roof cycle works as it should.

Any help will be greatly appreciated as it has me confused.

I sell Crossfires and have 22 in stock currently so have tried swapping the roof ecu and everything is the same.
