Mysterious eletrical problem in 2000 Toyota Sienna by zombieraptor

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.

Nevermind, it was a battery issue. Not that this forum gives a damn.

Same Problem But Battery is New by xcentrick

I have a similar problem. All of a sudden my remote wouldn't activate the doors locks. So, I checked my new battery, it checked out as good. Then, I removed and cleaned both terminals and cable connectors. After reconnecting the battery, I tried to start the van and it started immediately. Now, all electrical assessories work EXCEPT the door locks and rear sliding door on passenger side. When I try to activate the door locks internally I hear a clicking sound. Also, the courtesy lights are flickering very dimly. When I tried to manually lock the doors, a continuous clicking sound was heard.
 
I would appreciate any help.

I fixed mine. I replaced the Integrated Circuit Relay with Door Control, P/N 82641-08020.. Part costs $200 dealer only. It took me about 4 hours to put it in. Don't try this unless you have infinite patience, an advanced set of tools and skills with auto electrical. You have to disconnect the battery, remove the two dash panels under the steering wheel, the driver seat and the driver's running panel and the kick panel. Then, you have to completely disconnect most of the connectors to the fuse box so you can drop it down. Once the fuse box is down remove the old unit which is mounted on top of the fuse box and mount the new one. This is one of the more challenging ones I've tackled because of the tight space you're working in and compactness of the wiring.
