    I just replaced the heater core on my wife's 99 Mustang. If I engage the flasher button, flashers do not work but the turn signals will work. Rookie mistake I am sure. Fuse 13 & 18 look ok.

    You likely have a ground wire beneath the dash that was either reconnected incorrectly or not reconnected at all.

    Not too sure. The Flashers use the same G204 ground as the turn signals. It is also the ground for a pile of other stuff that works. I've got the pin out check for the Multi Function and might try that.
    I did pull the column, but the Multi Function portion of the harness remained.
