If they ALL don't work, try changing the Bulb Failure Relay (big round red). At least this is what the 740/940 have as a common failure for brake lights.

just the brake lights dont work. the running lights, reverse lights turn signals and fog lights all work. just nothing happens when i step on the brakes. what do you think about that?

Are all bulbs burned out? Unlikely but possible? Ground connection OK?
