I hope you are not trying to get the fogs on, it is a dealer programming function, the bulbs were removed in some states and programmed out due to some state laws due to their location. It is a two step process, one activates the circuit, the other activates a bulb in the cluster. I dont remember how to get the panel off, mine got traded after the first year!
