Sounds like you exceeded the limit switch travel. #1, feed the cable back into the gearbox in the headliner. You will have to get into the mechanism at the DS rear panel area - it can be done. Seldom will you have relay or electric motor failure on the roof - it's usually the gears and the limit switch issues at the root of the failure. With the drive cable pulled back so far, you will have to manually feed it forward again.
It's all relatively easy to do - but you must be patient! 2-3 hours max to re & re IIRC - check post
