Function and Common Issues
The rear hatch glass lock secures the rear window in closed position electronically. Over time, repeated use, environmental exposure, or electrical faults may cause locking inefficiency or failure. Common signs include difficulty locking the rear glass, unusual noises during locking, or complete non-response from the lock.
Replacement is recommended once the lock shows signs of wear or malfunction to maintain vehicle security and proper function of the rear hatch.
Replacement and Installation
Installing the rear hatch glass lock involves removing interior trim panels of the rear door to access the lock assembly. After disconnecting the electrical connector and unscrewing the mounting bolts, the faulty lock can be removed.
