Hello, first time poster here.
Today my wives 2005 Lexus GX470 started making a weird humming, compressor like noise every time the car starts up. It happens whether I put the key in the ACC position or turn the car on completely. It goes for about 20-25 seconds and then stops. I turned the radio off and the air and the noise continues. I was hoping to see if anyone has ever dealt with anything similar and what they ended up replacing to solve the issue. Any help is greatly appreciated!!!
