Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
No dash lights and tail lights on the C5 corvette is a telltale sign of a bad multifunction switch. You can test it with a multi-meter, but it is common enough that I would just suggest replacing the switch. Do you plan to fix it yourself?
Here is the test procedure:
1. Check the PK/TLP fuse.2. Disconnect the multifunction switch connector.3. Jumper pin R, Brown wire, to pin Z, Orange wire, on the vehicle side of the connector.4. If the park lights come on, the multifunction switch is defective.
