I was driving my 86 k30 to work today and it seems like some graemlins have taken over my rig. The first thing I noticed, the turn indicator lights were dim and working slowly, when I turn the headlights off, they worked fine. Next, when I tried to turn the rig off, it wouldn't shut off until I let up the brake pedal. During break, I unplugged the light switch to see if that was causing issues. That didn't change a thing. While I was under the dash, the box next to the brake pedal was making a buzzing noise, when I push on the brake. Not sure what that box is or does...(I'm a 73-80 guy). Also, when I turn the key, I get a quick buzz, while turning the rig off or on. I'm starting to wonder if there is a short in the brake or ignition switch.. Anyone have any ideas what I should look at first??? Thanks in advance.
