Headlight Problem
 

'88 944 N/A
When I have my dim lights on my drivers side light doesn't work. I checked the fuse box and the fuse was blown. When I replaced the fuse my fog lights wouldn't work, then an hour later it blew the fuse and I was a one lighter again. I've looked around and I can't see anything that would make the fuse short out, but then I don't really know what I should be looking for. Any ideas? Any help would be appreciated.
