So, I bought a 1996 Bluebird. During the seat removal process the annoying buzzers caused me to go snipping wires. First the one just to the left of the back door, then the one just above the center/left emergency door, and then the wires right under the armrest for the drivers left arm. The last cut of the two wires to that armrest buzzer caused the interior lights, radio, windshield wipers and fans to no longer work. I went looking for fuses, but it doesn't look like there are any fuses.
Hoping that someone made the same mistake and has a solution.
It seems there's at least one person a week that has problems from cutting the wires on the door and hatch switches.
There are several instructional videos on youtube that hopefully can help with your problem. By cutting the wires you've activated the interlock, which means the bus goes nowhere. You've got to learn how to disable the interlock system in order to start your bus.
The problem is disabling the interlock seems to be a little bit different on just about every bus. There is information available but it may not be directly related to your model of bus. This is going to be a learning experience for you.
