There is a recall not sure of the years but it is to replace your hazard switch. Your hi-mount would work but no brake lights call the dealer and ask if your truck is in the recall.

If the third light works and the turn signals work its the turn signal/hazard switch in the steering column. try jiggling the hazard button and see if they come on
