I just purchased a 2003 Lexus GX 470 with 195,000 miles on it. On start up when the engine is cold, there is a noise coming from the right side of the dash that sounds like a pump for about 20 seconds and then stops. It appears to only make this noise when the engine is cold. I thought it was the compressor for the airbags but found out that that is located at the rear of the vehicle. Thanks for any help.
