My pal has an ML that has started behaving badly recently. Problems include alarm triggering apparently by itself, wipers activating by themselves, problems with interior lights, dashboard 'lighting up' and other such intermittent electrical problems. Any clues? Is there a control unit for this lot located in the floor pan somewhere? Do these cars suffer from blocked drain tubes which can lead to water ingress causing damage to circuitry somewhere? Any help would be much appreciated, Thanks.
