Another roof question..red and Orange light flashing?

[johnnnnnnyy]

Yes another roof question, but I also did lots of searching before posting.

My roof motor was replaced a couple of years ago and car is always kept dry in a garage, so won't be the motor.
I've got both the red and orange lights flashing and roof won't move at all (already up and locked in place). I checked the shelf in boot, shook it and still nothing.

Could this be a dodgy sensor?

I take it the shelf was on the lowest position?

Yes it was. I've never actually moved it since I owned it. I did raise and lower it (shelf) to see if a censer was stuck.

Would certainly be my next check

Where is the sensor located?
