Without details of the age of your car, all i can suggest is you look in car handbook to identify and locate the fuse that protects that circuit. Check it is not blown and replace if necessary. As a guide, I think your fuse box will be under the steering wheel behind a flap next to the door. Locate Fuse numbers 14 and 16 and check those first
