I wouldn't panic quite yet. Can you do basic diagnosis yourself? Check the accessory (10A) fuse, thats what powers the T/S switch.
Heres the wiring diagram:

Stick a test light (or DVOM) in the plug that goes to the switch. It's behind the cover at the headlight (Orange/white stripe). Got power there? You can even check the outputs (W/Bn and W/V) to see if the switch is even working. If you have power to it and it is not working, I have a new one for you.
If you have power and the T/S switch is working, ya the next step might be an ECM or Dash, or a different repair like adding a cheap T/S relay.
