Question about 1999 Chevrolet Express
You can test right from the starter relay ,located in the under hood fuse relay box . You want to know if the starter is good or bad or if the control side is the problem . Turning the ignition switch to start sends B+ voltage to the park neutral safety switch an through the coil side of the starter relay to ground ,if the park neutral switch is good . Try moving the gear selector into neutral to see if it starts then .
Looking at a wiring diagram would be a good first step in the diagnostic process. Free wiring diagram's here http://www.bbbind.com/free_tsb.html Enter vehicle info year , make , model and engine size . Under system click on engine then under subsystem click on starting . Click the search button then the blue link . Pull the relay an look at the bottom , you will see four numbers . 30 - 87 & 85 - 86 . Take a piece of 12 gage wire ,jump where 30 an 87 plug into the relay socket . If the starter is it will spin the engine over .

When you said that you checked the brake switch, did you check it live? Meaning verified live power to the switch, press switch, and then power came out the other terminal?
If so, also verify zero power on brake press, at the offending brake light bulb terminal. You must verify the test light each time you move it...leave running lights on...
After verifying that there is no power coming, after the brake is pressed, note the wire color and find it where it comes to the steering column and test there... This would eliminate wires and connections between front and the rear of the vehicle, unlikely, but needs to be tested.
After verifying no power at that terminal, then yes the t/s switch is certainly suspece. This may be the time to get a mechanic to verify and replace the switch, there are locks, tilt mechanisms, air bags, column bearings, etc involved. Failures risk loss of vehicle control (locking or binding for example.)..
Hope this gets you going in the right direction.

Testimonial: "Thank You. I tried those things and it seemed to be the Emergency Flasher switch in the multi function switch."
Try under the dash, attached to colum is a switch that the rod goes into from your ignition key switch, that may need to be adjusted tword your steering wheel just a touch, they go out of alignmnet from time to time
