I forgot to close the driver side window in water from the sprinklers got all over the interior. Since then I have had a host of electrical issues. Something the red air bag light come on and other times not. The radio works but does not light up. The directions work but do not display on the dash. No air conditioning but it blows hot air. I have checked all the fuse and can not find and that are blown. Before I head off to my local BMW guy and blow a lot of money, does anyone have a suggestion as to how to diagnosis the problem and recommend a solution?
