I have an intermittent buzzing noise when the car is running. It gets louder and more often when the car warms up. I took it to my local Honda dealership named o'donnell Honda in ellicott city, MD. The supervisor mr. Jerry furr of the service department said he never heard of a diode in the alternator yet I found on google that this video showed that exact problem. I also came in to get my glove box repaired because it is almost impossible. They said it would be extremely expensive because they would have to replace the complete glove box. So, they said just pull on the bottom of the door of the glove box and it may or may not open with trial and error. That glove box was probably defective when it was new. I bought this car from carmax in 2010. This problem with the glovebox should have been fixed in 2007 when the car was new. So, I spent several hours at the dealership and they gave me back my car without doing anything and they charged me $69. What a waste!.
The passenger windows (1 front & 2 rear) stopped working. When they stopped working, the windows were partially down. I could not raise the windows by any usual means. All I would get is a clicking sound at the master window control and the individual respective windows controls when I tried to raise them. The only window that would operate in a normal manner was the driver's window. The driver's window would go up or down as needed without any problem. This appears to be an electrical issue that has affected many Honda models of various years, including models newer & older that my 2007 Honda Accord se. The issue does not involve a window regulator, nor window motor. It appears to involve the master window control and/or the vehicle's ecu (electronic control unit) that is responsible for the operation of the vehicle's windows. This problem should be addressed by Honda at no charge to owners of Honda vehicles.
The regulators of two rear windows made loud noise during window open operation on sept. 22, 2011. One of the window was not able to close all the way up after it was open. These two windows only are used less than a dozen times. It was raining that day. The windshield was smoggy while I was driving because the window was not able to close. The defrost was not able to clear the windshield. This defect can potentially resulted in fatal accident.
