I have two issues, first thing is my horn now doesn't work, yet when I hit the horn button the interior light at my feet turns on and buzzes, no sound comes out of the horn. Second is my ebrake doesn't work I pull and it has tension then it falls right back down to the ground, brake light on dash turns on but no brake is working. Any ideas how to fix either one.

A really good write up for the E brake is actually on the main page of this site. Here is the link:

As far as your horn not working, has it worked when you first got the car? The fact the light is going on seems like an 'interesting' electrical issue. Check out simple things like the fuses, and connections to the horn. Im almost leaning towards the horn was rerouted and wasn't fully connected by the previous owner?

Yep. screwy electrical issues usually come from a blown fuse somewhere. When a fuse blows, you would normally think that something just stops working. Nope - not GM. The circuit will find all kinds of alternate paths. Checking all your fuses is a good place to start. Maybe even check the fuses themselves with a meter before putting them back in. I've had fuses "look" good but wouldn't pass current.
