Where is the air conditioning relay located in the old Land Cruiser Prado?

Toyota Land Cruiser Prado's air conditioning relay is located in the control cabinet or control box. Here are specific details about the relay: 1. Overview: As an electrical control device, the relay connects in the circuit to form both the control system and the controlled system. 2. Installation location: As an indispensable safety control component in control circuits, relays are installed in control cabinets or control boxes. Due to the variety of relay types and models, it's difficult to specify the exact location without referring to the specific circuit diagram. The relay is connected in series in the main circuit, and you can trace along the circuit to find it. The relay has several main contacts plus two coil contacts.
I just serviced a few old Land Cruisers. The AC relay is usually located in the engine bay fuse box, near the left front corner close to the battery. When you pop the hood, you'll see a black box with labeled relay numbers—for example, the AC relay might be labeled 'A/C Relay' as R2 or R3. If you can't locate it, check the diagram in the owner's manual. The position varies slightly by model year, but it's mostly the same. Aging relays often cause issues, like the AC not cooling. First, try removing the relay to check for oxidized contacts and test continuity with a multimeter. Don't disassemble recklessly to avoid damaging the circuit. I've seen many owners fry fuses by tinkering blindly, making things worse. If unsure, visit a professional shop—old car parts are cheap and easy to fix. Remember, safety first: turn off the engine before inspecting to avoid electric shocks.
I drove an old Prado for over a decade and once had an issue with the air conditioning relay. It took me quite a while to locate it. It's usually positioned in the fuse box in the engine bay. After lifting the hood, look for the plastic box on the left side, which contains several small components—the air conditioning relay is one of them, clearly labeled. If you can't find it there, try removing the glove compartment; sometimes it's hidden in the inner box. That time when my car's AC failed, I spent time troubleshooting it myself and eventually fixed it by replacing the relay. I recommend keeping a spare relay in your car just in case the old one fails on the road. Wear gloves to prevent electric shocks when checking, and take your time—no need to rush. Maintaining an old car is all about attention to detail. The relay's location isn't hard to find, and the manual is your most reliable guide.
