Can anyone tell me what the switches down below the steering wheel and next to the drivers door are please. One is for the fog lights but there are two more. One of them has a light type symbol and the other one has a windscreen wiper and heater element symbol together. Also, under the stereo there are a couple of controls - one is to wash the lights I think but as my washers are busted, I don't know. One of the remaining two is the headlight level adjuster for when towing or under heavy load. The third one is what has me stumped, it says bright on one side. Thanks.
