need help. keeps blowing #9 fuse for brake lights when both the brake and clutch is depressed. have chenged both the brake pedal switch and multi function / turn signal switch.

 

I'd look carefully at the wiring which came in close proximity to the clutch pedal mechanism. You'd get these symptoms if the clutch levers were pinching the wire to the brake lights. Clutch alone wouldn't blow the fuse because there's no power on the brake light circuit. Brake alone wouldn't blow the fuse because the clutch wasn't pinching the wire. A combination of pedals would apply power to the brake light while the clutch was pinching the wiring. Worth a check out.
