I noticed the other night at work that my brake lights were on. I went inside and thought the pedal was sticking so i pushed it down and the lights went off. I had parked it in the garage this past week and noticed the lights on again so i did the same thing to turn them off. Ultimately this morning i got to open the back window and it wont roll down. Battery's dead.

1985 Toyota 4runner.

1. Brake lights will come on even after i made sure they are off and pushed the pedal a couple of times.

2. lights will come on intermitently.

Questions:

Is the a micro switch that is connected to the brake pedal? Do these usually go bad?
BTW i searched.

Dead again

Just got back tonight and my battery (optima) is dead again even after pulling the fuse for the brake lights.:confused:
Whats the best way to check for a short?

With everything off, connect an amp meter between the positive cable and the positive terminal of the battery.

Current drain of 50-100 mA or so is normal, greater indicates a problem. Start pulling fuses to isolate circuit with high current draw. Once you've found that, find out what on that circuit is the problem (a wiring diagram helps).
