Consider leaving the jacks down and the coach level. Start the engine. Wait about 10 seconds and then store the jacks. Sometimes the ride height levers/valves get "stuck" and do not send air to the bags. Following this procedure allows the ride height mechanisms to be jostled so that they will allow air to the bags.
