With 12 volts connected directly to the blower motor it will run at it fastest rate as long as the ground is good. You'll want a fuse and a toggle switch in-line with the 12 volts, so that you can disable when not in use.
here are a few diagrams for the gbody if you need them:

There's also another relay in front of the air box. Its a little bigger then a a pack of tic tacs that controls the high speed. Look there.
It's usually attached at the starter via fusible link.
I honestly can't believe how common this is.

Take a look at a connection that is on the passenger side close to the front of the engine. If that connection or the wiring has fallen onto the exhaust manifold or headers the red power wires for the fan may be burnt or the connection itself may be fried.

I've actually seen that connector unconnected on many G-body's over the years. I don't exactly know why.
no use starting a thread if you are not going to take to time to read the suggestions posted
