Sounds like you replaced the wrong flasher. If you replaced the one in the fuse box, that isn't going to do the trick. The fuse box "flasher can" is for the 4-way hazards. The "flasher can" you want is IN the dash above the steering column or near the radio(they like to move around). Look for a little plastic or metal can with wires (usually purple and pink) plugged into it. Bottom line is, check that flasher IN the dash.
