the EXT fuse keeps blowing. when i replace it the ext lights work but the blinkers do not.
i did some research and replaced the highmount brake bulbs ( one was very burnt and buldging). but the problem persists. when the fuse is not blown the blinkers will light up but not blink. when the fuse is blown the exterior lights do not work but the blinkers do. i have looked briefly at the trailor wiring harnes and it looks good. its a uhaul hitch package
