Most likely it's your fan. When you hear this do you have the AC or vent on? try turning it off a bit before you turn off the engine.

There are a couple of relay switches in the side of the top on the driver's side. One of these is not working. Your break lights are out because of this too. You have to apply the brake to lower or raise the top.

Bushings in seat are shot. See this link: http://www.youtube.com/watch?v=DM4KSnA58EI

it seem like you are having problems with the ignition switch,replace it and it should be fine.goodluck"!!!

If you are looking for the location of the Steering Wheel, it is underneath the manifold close to the air filter.
