How were you measuring the amperage? For voltage you can measure between the supply wire and ground, but for current flow you're measuring between supply wire and the terminal of the blower motor that it connects to, yes? And the blower motor has a good ground, right?
At this point I'd be curious to swap in another, known-good blower motor just for yucks...
Incidentally, with the ignition on and the engine _not_ running, you should be able to hear an audible *click* from the high-speed bypass relay when you switch your fan control from any lower speed to the Hi position. Try going back and forth a couple of times, in and out of Hi, to be sure you're hearing a click from somewhere.
P.*. If you want to hotwire the blower temporarily (which might not be a bad idea anyhow, just to prove that it works in its installed position), any 15-amp toggle switch should be okay. Make sure you're using a fused circuit, though, so that you've got something that will blow if overloaded, such as if the blower motor seizes up.
