95 silverado no brakes turns hazards

[tomsteve]

i hope im posting this in the right forum.

this is my nephews truck and he lost all rear lights yesterday. i checked the fuse panel on the side of dash and fuses were good. went under the hood and 30 amp fuse for brake/hazards(?) was blown so replaced that. we have running lights now but no hazards, turns, or brake.plus the door buzzer isnt working. i swithced two relays in the underhood fuse box around and still the same.

im rather mechanically inclined except when it comes to electrical.

searching the www i think i overwhelmed and confused myself on where to start diagnosing. seems blowing a 30 amp fuse would be a pretty good short in the wiring, but im not sure if i should start tracing wires and look for a short or if theres a common problem these trucks have with this part of the electrical system to look at.

all help would be greatly appreciated by both me and my nephew.

for those interested, the 95's have the hazard and turn flashers combined.

My truck had the same problem, turns out, it was my indicator switch. I'm no expert mechanic, but but I bought a new switch and it was fixed.

D1256E is what I bought to fix it.

If that doesn't help, I don't know what else it could be.
