I think I have a blown fuse..no turn signals or fan for air How can I get a diagram of fuses?

Here's what I found out by accident. Get in the car, turn the fan on all the way. Start car, while engine running, back off the ignition switch ever so slightly, just a wee wee bit until you hear/feel the blower motor running. If you stall the car, you've gone too far. Temp. fix, but great when you're, for example, in the desert with no new ignition switch and it's 129 degrees out. Hope this helps! Cheers
