Short in car need to find out what btn stands for?thats where short is.
If you are refering to the 40 Amp Maxi Fuse located in the engine compartment fuse block, the "BTN" fuse is one of the MAIN circuits to your instrument panel fuse block. It provides power for:
electronic flasher, brake pressure switch, brake on-off (BOO) switch, door lock/unlock relays, park lamp relay, shift lock actuator, luggage compartment lamp, remote anti-theft personality (RAP) module, integrated control panel (ICP), dome/map lamp assembly, key in ignition switch, inhibit relay, powertrain control module (PCM) and the horn relay.
If this fuse is blowing, none of the things listed above will work. (and your car will not run). You will most likely find the short in the harness between the engine compartment fuse block and the instrument panel fuse block.
The wire you need to check is the RED/WHITE wire (large diameter) that goes from connector C-109 Pin 1 at the engine compartment fuse block to Connector C-240 Pin 6 at the instrument panel fuse block.
C-109 is located UNDER the engine compartment fuse block and C-240 is located BEHIND the instrument panel fuse block. To get to the actual connectors, you will have to remove the fuse blocks. However, you will most likely find the wiring harness rubbed through somewhere in the engine compartment and won't need to get to the connectors themselves.
