Clicking noise with ignition on
 

1991 ZR-1
When I turn the ignition on but don't start there is a steady clicking noise. I tried to locate source but no luck yet. It appears to continue for as long as the ignition is on. Insights?? Thanks

Does your power antenna work? could be slipping
Maybe a plenum door in the HVAC system?
You could start pulling fuses to see if you can isolate the system.

Might your battery be discharged?
If below a certain voltage various things cycle on and off making such a noise.
Get your battery charged and tested, then let us know if it is still going on.

If the bushings in the headlight motors have turned to dust the motors will run continuously making an odd noise.
Try turning on the headlights, if they don't rotate, theres your smoking gun.
