* Under the dash: While less likely to be the *relay* itself, the wiring for the A/C system often runs under the dash. There might be a junction block or connector there related to the system.
* In the main fuse box: While not typical, some older vehicles integrated the A/C relay into the main underhood fuse box. Check your owner's manual or a wiring diagram for confirmation.
* Near the A/C compressor itself: This is the most plausible location. It is often positioned to allow for easy access to the compressor clutch circuit.
To find it definitively:
1. Consult a wiring diagram: A wiring diagram specific to your 1985 Corvette is crucial. You can find these online (often via forums dedicated to that Corvette year) or in a repair manual. The diagram will show the relay's location and possibly its part number.
2. Trace the wires: Locate the wires going to the A/C compressor clutch. Following these wires back will lead you to the relay. Be careful not to disturb any connections.
3. Check the fuse box: Thoroughly inspect the fuse box, even if it doesn't appear to be a dedicated relay location. Some relays might be integrated into a fuse block arrangement.
Without a wiring diagram, pinpointing the exact location will be difficult. A repair manual specific to your vehicle year is a highly recommended investment for such situations.
