2005 Grand Prix Electical Problem

2005 Grand Prix: I got in the car and pulled out of my driveway when I noticed a funndy smell. I made it 3 houses down when my car totaly freaked out. Suddenly, the horn started honking, the wipers started going 90 miles and hour and the emergency flashers started flashing. I tried to turn everything off to no avail when I noticed what looked like a small stream of smoke coming from the instrument panel. I immediately turned the key off, which stopped the wipers, but the battery cable had to be removed to stop the horn and flashers. That is when I noticed that several of my relays are burnt. (A bit of history - About a month ago, I was getting messages that my turn signal lights were out, all four of them, one and then anouther. I assumed it must be a fuse so I had the fuses and light bulbs replaced. After that, I still had a message that my front left turn signal was out. No other problems that I am aware of.) Could this be the computer or some other part that needs replacing or is it likey a short in the electrical system? I called the dealer and explained my problem and all they would tell me is that I need to bring it in, they charge $98 per hour and it would probably take several days to figure it out. I do not have 800 bucks a day x several days + the cost of a tow truck. And, I certainly can't afford to run up a bill then not be able to pay to get it out or spend money on a wrecker to and from the shop and still not have transportation. Any suggestions will be grealty appreciated. Please help! - Damsel in Distress.
