I'm working in my grandson's car. His idle goes up and down with the A/C off. I can't figure out where the IAC is. He just bought it and we don't have manuals or diagrams yet. Can someone help me figure out the IAC location? I want to take the old one to our parts store to make sure the replacement is the same.
If you have the 2.3L 4cyl, it should be here just behind the throttle body on the passenger side:
If the V6 (either 3.0 or 4.0), I think it should be right on top of the intake like it is on this V6 Escape:
If it isn't there on the V6, you should still be looking for the same shaped part. It should be on the outside of the intake near the front and is usually plainly visible.
