The manual sunroof is controlled by a set of cables which pull the sunroof panel along guide rails when the crank is turned. The sunroof can be adjusted without removing it from the car, however, replacement of the sunroof liner or components such as the cable assembly require sunroof removal. If the sunroof leaks or sticks, adjust it as described in 7.2 Adjusting Sunroof fit before deciding that it needs to be removed from the car. Leaks may also be caused by clogged drain hoses. The front hoses lead from the A-pillar into the space between the front fender and the door. The rear hoses are reached after removing the rear bumber. Clean the hoses with a length of flexible cable, such as an old speedometer cable.
