1996 Chrysler Concorde Turn Signal & Hazard Lamps

Every time I turn on my Hazard Flashers it pops the fuse in relay box under the hood. I took it to a mechanic a few months ago and he said to repalce the multi function switch which I did. The turn signals work fine, until I turn on the hazard lamps and it knocks out the main fuse under the hood then nothing, turn signals or hazard flashers work.
