I was getting in my van to go run an emergency errand, and as I approached the van I heard a strange, repetitive clicking sound that I had never heard before. I didn't know what to think of it and as I have other problems and didn't want another, I decided to ignore it. As I got into the van, I noticed that the dash lights and the lights on the door panels were flashing and blinking in rhythm with the clicking. They were also far dimmer than they should be, the lights. I tried cranking it, and of course, it did not turn over. I popped the hood and tried to find the mysterious metronome. It seemed to come from my electrical box-thing. I opened it, and the clicking seemed to be coming from one reddish-brown cube in the circuit box. I messed around with it a little, and when nothing came of it, I got back into the vehicle and tried messing with stuff to try and get to the bottom of it. I turned off the electrical door; nothing happened. I kept turning knobs and pushing buttons; nothing happened. Then I put my foot on the brake. The clicking stopped. The lights were steady. I took my foot off of the brake, and it started again, the clicking, the blinking. My brother was driving it earlier and said then that the brake pedal didn't feel right. So I am very confused. Is it an electrical issue or a brake issue? Both? Something on the battery? I have no idea, and if I don't get a running vehicle by midnight I will be in some deep trouble, as the emergency errand I need to run requires a vehicle. Please, help me out if you can. Any suggestion is welcomed.
