Does anyone know what would cause the sunroof on a 2001 V70XC to operate eratically? The switch doesn't seem to be the problem and a new power module was put in for a test but that didn't solve the problem either. Is there a relay or circuit-breaker in the system that controls the sunroof? I read something about a software problem causing power windows troubles in the V70. Does anyone know if there is a reset procedure? Thanks.
