Where on a 92 Chevy suburban do you find an ac compressor relay switch?

The 1992 Chevy Suburban's AC compressor relay isn't a simple on/off switch like a light switch. It's an electrically controlled relay that's activated by the system's control module. Therefore, you won't find a "relay switch."

The relay itself is usually located in one of two places:

* Under the hood in the underhood fuse block/relay center: This is the most common location. The fuse block is typically near the battery. The relay may be labeled, or you might need to consult your owner's manual or a wiring diagram to identify it.

* Inside the passenger compartment fuse panel: Less common, but possible. Again, your owner's manual or a wiring diagram will be necessary for identification.

To find it, you'll need:

1. Your owner's manual: This will have a diagram of your fuse and relay boxes.

2. A wiring diagram: A Chilton's or Haynes repair manual for your specific year and model Suburban will have detailed wiring diagrams. These diagrams show the relay's location and the wires connected to it.

3. A multimeter (optional): If you can't visually identify the relay, a multimeter can help you test relays to determine which one controls the A/C compressor.

Caution: Always disconnect the negative battery cable before working on electrical components in your vehicle. Incorrectly working with automotive electrical systems can be dangerous.
