c320 headrest's wont work
 

hi i just bought a 2003 c320 the car is awesome and everything works fine. the only problem i have is that none of the headrests work including the rear ones. when i press the button for the front headrests i hear a clicking noise from under the seat.. which means the relay is working and i didn't find any burnt fuses in the trunk. any help would be appreciated thanks :)
