If the cruise control isn't working on Your Land Rover Discovery model one the most common reason is going to be because You have a crack in Your vacuum line. You're going to want to go ahead and pop the hood of Your vehicle and then inspect Your line to make sure that there is no damage to it. If You start to see any breaks in it You're going to want to get it replaced. The total cost of parts and labor to have one changed out will be between $300 and $500.
