New member here, so replying very late, but here's my two cents.
I have the same problem on a 2005 Bentley Arnage R. After two months of ownership, I noticed all 4 windows intermittently won’t open at different times. I haven’t had a window open then not close again, so far. The problem would occur randomly but would usually resolve itself a few hours later. I even had the driver window refuse to open for a week then start working again. I chalk this up to the jolts and bumps a car receives during normal driving loosening the window drive engagement mechanism. So I spoke with a full-time professional Bentley mechanic and here are the pieces of advice we came up with;
- (Mechanic) This is a very common and well know problem. It happens all the time and is usually due to lack of use of the windows. Must exercise windows regularly.
- (Me) Put the ignition key in appropriate position (accessories, engine not running), make sure the dome lights are on and press the window open button up and down a few times to see if the dome lights flicker. If so, then the motor drive mechanism for the window is drawing current and probably stuck. I’m assuming you have already checked the fuses and eliminated that.
- (Mechanic) Try slamming the door as much as you dare (without damaging your royal carriage) while simultaneously holding the window open switch. It’s a little like the old Bendix starter motor jam where you had to engage third gear and rock the car to free up.
- (Mechanic) Hit door panel inside with your hand while holding the window open switch.
- Disconnecting the two batteries on an Arnage is not usually recommended as there are many items that have to go through a re-learning process or Initialization. The windows have jam sensors and have to re-learn their position. I am still researching this part, but I believe there are many other items such as clock, trunk emergency release, radio security code, etc., that need reset. Hopefully the car anti-theft immobilizer PIN is not one of them.
I agree with previous comments, don’t rush out too quickly with wallet in hand.
Hope this helps,
