he TCU is a timing control unit. It is a small white box that is located to the left of your fuses that are under the driver side dash.

If you take it off and unscrew it, you will see a Printed Circuit Board with a lot of mounted components. The side with fewer mounted components that looks like it has green paths running around will most likely have one of those traces burned out. You can tell if its is black. I didn’t replace my unit and just fixed it buy soldering in a wire where the burned out trace was. But if you find that yours is burned out you can just replace it, and that will fix the problem too.
The problem is the circuit that lights the dashboard lights, as well as the climate control knobs, and glove compartment is powered by a red wire with yellow stripe (-) and red wire with blue stripe (+). These wires also go to the wire harness for the stereo and are usually not used.

On my S14, the power wire that goes into the gauge cluster was my issue. Somewhere between the fuse box to the cluster, shit is grounding out. I just cut that wire out and run a different 12 v power source to it. Might have pulled it from the radio. Ghetto but it worked.
