Turn signal flashes as if truck has blown bulb

There still may be a bad bulb in the batch, the flasher for Hazard Warning/Turn Signal may be bad, look it up online for your truck year and model to see the replacement and look under dash for it and replace it, It has plug connector.

All the bulbs work unless i either hit my brakes with no lights on or all the time with my lights on. Those are the only times the lights work. The hazard warning/turn signal flasher is clicking along with the dash indicator. I used to be able to spray the brake light fuse and the turn signal fuse and they'll work perfect for awhile. The fuses seem okay, I didn't use a tester but the metal inside is attached. Also I forgot to mention, when I hit my brakes, the only lights in the back that I have is my cab light up top.

Did you ever figure out the problem. My 96 is doing the same thing right now and I’ve replaced the boards on both lights , checked my ground and replaced the bulbs. Also replaced the relay for the brake lights and all fuses are good

Jr any luck? My 94 chevy is doing the same thing?

Check the big 50 amp fuse under hood on driver fender wheel
