Ok here is my situatuon i have a 1993 d250 and on my way home from work my brake and abs light came on. Than as i was goin to turn my turn signals quit hazards quit. I go and check the fuse the brake light and hazard fuses were blown. Interior buzzor is no longer working when the door is open but buzzes when i turn acc on before i start it by pressing the brake petal the buzzer noise changes tones. I believe my brake lights are not currently working either. My running lights and license plate bulb works. Any ideas or suggestions would be greatly appreciated!!!

 

Replace the fuses then report back. Do NOT install higher amp fuses.

 

Ok using the original amperage fuses everything works until i turn my right turn signal on (left is fine) then the turn signal fuse blows, and the abs and brake light turn on then no turn signals. If i press the brake pedal the brake lights dont come on and i blow the brake light fuse.

 

Then you have a short.
Start taking stuff apart, could have some mice or something that have decided to eat your wiring.

 

I have found the cause of the issues the plug that holds the wiring to the frame came loose and decided to plop on top of the exhaust pipe melting through the casing and exposed wires touching the pipe shorted everything out
