2001 E320, remote locks and unlocks the doors. When the locking switch on the console is pressed there is a motor running sound, but not as "many" motor sounds as when remote is pressed. And locks don't operate when using the switch. Is this switch replacement? There is no way I am capable of removing the dash unfortunately. Advice appreciated!
