Clicking

I just purchased a 2002 Chevy Trailblazer.

Everything is great other than the following two items:

1. At a certain point, if the steering wheel is in the right position (generally not turned) there will be a clicking feel in the steering wheel and also sometimes at low speeds while turn. It is not constant and there is no noise associated with it. My first thought is CV Joints...any suggestions?

2. When I turn the vehicle off on the left side within in the dash there is a noise...almost like air escaping from something? No thoughts here.

Thanks,

Brett
