Ive never had a problem with mine....
Im guessing you have checked all the fuses? In the dash as well as under the hood? Are all the bulbs good? Does your 3rd brakelight still working?
Heres a guess:
maybe its the Multi function Module? Its in the steering column....
Have any idea what may have caused them to go out in the first place?
Hope this helps!
maybe someone else will chime in with some other ideas/advise!
