Default Shifter Lamp

Anyone know what circuit the lamp is on that illuminates the PRNDL letters in the console at the shifter? Mine doesn't light, which makes knowing what gear you're in at night almost impossible.

Replaced the bulb but seems the circuit's not getting power. Looked through all the wiring manuals and can't find anything about this lamp. Really don't want to take the dash apart to trace the wires.

It gets power from the 3 amp inst fuse. There is a large junction in the wiring harness above the radio where all the instrument panel lights (including the shifter light) get power.

Default I had the same problem

A really nice guy helped me through this so if this helps it was all from someone else here.

Check out this thread:
http://forums.corvetteforum.com/c4-g...d-on-this.html

There are a few pics. Some by me and some by the member who was helping me.

He helped me via private messages. He was great.

Ultimately it was determined to be a dimmer switch under the driver's side dash. Specifically, it runs down the left hand side of the steering wheel column. It was burned up. I replaced it and everything worked. As a matter of fact, a whole bunch of stuff started working.

I was getting no juice to the fuse box. By shorting out two of the wires, he determined that this dimmer switch was bad.

Here's a link for the part I replaced:

I'll be glad to help if you see similarities in your problem as mine.

I know there are multiple possibilities and only one solution.

let me know

Thanks for the info. All other lights in the dash light and dim properly so seems odd that would be the cause of shifter light not working. Going to check the fuse voltages.

Wish I could find the schematic in the service manual.

I believe there are two pictures for the schematic regarding that bulb on the first thread. Check and see if you can read them.

Found the lamp in the schematic in Electrical Manual Supplement 8A-117-1.

Thanks for the info... the "R INSTR" fuse was blown. Problem solved (unless it blows again!).
