2001 Lexus LX470 ProblemsLoud Vacuum Cleaner Noise on Cold Start
Drivers may hear a loud noise, much like a vacuum cleaner, coming from their engine on cold starts. This affects the 1998-2005 Lexus LX470.
The noise is from the secondary air pump, which sends hot air to the catalytic converter when the engine is cold. This allows the catalytic converter to clean exhaust better, and lower emissions while the engine is warming up.
Pump failure may result in:
- Check engine light
- OBD trouble code P1445
- Smog test failure
Fixing the issue involves removal of the intake manifold, and replacement of the secondary air pump.
The Check Engine Light may illuminate due to an evaporative emission (EVAP) system fault. Our technicians tell us these EVAP system faults can be difficult to diagnose but it is not uncommon to find a failed charcoal canister or a loose or worn gas cap.

Since all the other windows work fine, its not the fuses. It does not make any noise when the button is pushed both from the door itself, and the driver's side controls. The light on door is working, so I presume its getting power. Does this mean the window motor is shot?
