First time poster, like to say Hi to everyone. I have a long multi question post, My 99 silverado's dash board started to light up like a christmas tree, the message center started flashing messages like, low fuel, low washer fluid, check transfer case. Besides that the lighted 4x4 buttons are lit when they feel like it, 2wheel hi is lit, and pushing the other buttons doesn't do anything. Not familiar with how things are engaged if they are electric, vacuum, or something else. Should I take it to an electrical repair shop, or a 4x4 shop, or what. Any help is appreciated. thanks.
