Dim compared to what ?
Wiring issues in the doors are very common, remove the door trim panel, physically locate the chafed insulation, cut/broken wires, and fix them.
If all your steering wheel functions are inoperative, suspect that the clock spring has dirty connections or has failed. Clock spring failure is not unusual.
The clock spring is mounted on the steering column behind the steering wheel. This assembly consists of a plastic housing which contains a flat, ribbon-like, electrically conductive tape that winds and unwinds with the steering wheel rotation.
The clock spring is used to maintain a continuous electrical circuit between the instrument panel wire harness and the driver side airbag module, the horn switch, and the vehicle speed control switches on vehicles that are so equipped.
The clock spring cannot usually be repaired. If the clock spring is faulty, damaged, or if the airbag has been deployed, the clock spring must be replaced.
