2003 z4 roof issue

[w1ndsurfnut]

Roof not working. Checked the 3 fuses relating to roof. All ok. I have no flashing lights on the roof control buttons. No motors at all are working, windows not dropping. If I run my impa software the car can see the button press for both roof up and down. I had 2 errors stored in there for the roof but I don't have a date stamp on them so not sure if they are related or not, but could be. I have error 67 arrester hook drive: open load when releasing. And error 68 arrester hook drive: open load when bolting. Ive got a feeling I have a broken wire as this stopped working a while back when I was testing the roof for something else. Opened and closed it several times on the trot and that is when it went. I guess open load could mean open circuit. I did find a post on here about how to trace the wires along the inside of the roof above the window opening but I cannot for the life of me find it now. Any help ideas appreciate.

Most likely is that the motor has died because its soaking wet.

If the motor was dead I think you'd expect it to at least unlock from the front and then get a red flashing light.
Could well be a broken wire as you suggest.

Just one other thing to check:
Do a reset on the windows. I know it sounds daft, but if the roof doesn't know where the windows are it'll do nothing.
I had exactly that with the roof down after taking seats out. Black clouds looming and no roof movement. Window reset and all was good.

Thanks for all the comments. I already tried the window reset procedure. There seem to be a few variations of this. I don't think it is a motor issue as before it went the roof was as smooth as butter, no slowing down or jerkiness. Also as mentioned Im sure I should have some light on the button control.
