Sunroof 99 s80 sunroof opens but willnot close I installed a new moduale and I got it to open but it will not close

The new module must be calibrated to the car. This might have to be done at the dealer. You can try the following sequence...
with the roof open, push the sunroof switch back for 6 seconds, then forward for 6 seconds. shut the key off for 5 min lock the car(best if you use the remote) and unlock it and retry, if no success, try to push the sunroof switch back 3x quickly, take key out lock car, wait 5 min unlock car and retest (use remote if you have one)
