hiya, having some issues with my car, the cruise control buttons do not work, the heater only blows cold air (head gasket is fine) just wandering if anybody know if these are minor fixes or could it be as simple as a fuse maybe, is there anywhere i can get fuse diagram as i dont have one in the manual. i know the heater could be a matrix issue as when driving a can occasionly smell what i can only describe as boiling water
