Where is the idle air control valve located on a 1995 Cadillac Sedan Deville?

The IAC (Idle Air Control) valve on a 1995 Cadillac Sedan DeVille is located on the throttle body. The throttle body itself is usually found on the intake manifold, near the engine's front. It's a relatively small valve, often cylindrical, and will have wiring connected to it. However, precise location within the throttle body assembly can vary slightly depending on the exact engine.

To be certain, you'll need to:

1. Consult a repair manual specific to your 1995 Cadillac Sedan DeVille: This is the most reliable method. The manual will have diagrams showing the exact location and appearance of the IAC valve.

2. Use a reliable online parts diagram: Websites selling auto parts (like Advance Auto Parts, AutoZone, etc.) often have diagrams you can search using your vehicle's year, make, and model. Look for diagrams of the throttle body assembly.

3. Visually inspect the throttle body: Once you've located the throttle body, carefully examine it. The IAC valve is usually a small component connected to it with electrical connectors and possibly a vacuum line.

Remember to be careful when working around the throttle body and engine components. Disconnect the battery negative terminal before starting any work to prevent accidental shorts.
