Blown fuse for power mirrors

The power mirror fuse on my 97 Venture blew. When I replace it with a new fuse, it blows within 3 seconds. What should I be looking for to fix this problem? Thanks!!!!!!!!!!!!!!!

Well, it looks like my mirror switch is fried. I pulled it out and its partially melted. My local dealer wants $49.48 for a new one - anyone know where I can get it cheaper? Part# 12369208

I would try www.rockauto.com, they will most definetly have it. cheap and quick. They list with year and part number, just click on the big red button.hope this helps

Thanks gunjes, Rockauto said they couldn't get one, so I ended up getting one from a junkyard for $26.25. Works like a champ!
