You can just remove it. The new one will need programmed with a scan tool.
The GEM module is to the left of the steering column.
The Turn Signal Flasher Module is located inside the Steering Column. Make sure you Disconnect the Battery as Airbag is right there on Steering Wheel! You can take off the Steering Column Covers by removing the 3 Screws from the Lower Steering Column Cover and then separating the Lower and Upper Covers, setting them off to the side. The Flasher Module is on top of the Steering Column behind the Mult Function Switch. To remove the Flasher Module, you have to Disconnect the Electrical Connector and Remove the Flasher Module from its Mounting Bracket.
Under the dash, blue module to the side of the steering column.

The DRL control module is located under the steering column on the left hand side!
It is under the dash near the steering column.
If you mean the CONTROLS on the steering column (audio and cruise control buttons) are not working, there is a module buried deep within the steering column that allows the wiring from these controls (as well as the airbag) to maintain their connections to the vehicle circuitry even while the steering wheel is turning. It is called a "clockspring", and it's a bear to replace. Runs $350-500 at the dealer. This problem is very common to the LS.
Sensors detect the motion and torque of the steering column, and a computer module applies assistive power via an electric motor coupled directly to either the steering gear or steering column. http://en.wikipedia.org/wiki/Power_steering
The ignition module is not on the steering column. The module should be located on the distributor, on the outside, right below the cap. There should be a plug with a bunch of wires going to it. You will need a special tool to remove the small scews that hold it on.
Under the dash attached to the steering column.
