Have you taken the door card off again to check that none of the wiring was disturbed when you were putting things back together?
I recently changed my off side regulator and it was a suqeeze getting the new one into the door panel, also the replaced switch pack might be faulty, put the old one back in and try that if you still have it
Hope it helps
