Hi hopefully someone can assist me with an issue on my 2013 Bentley GTC. When opening the drivers or passenger door the overhead interior lights do not come on. The overhead switch is in the right position to illuminate when opening the doors. But once the ignition is turned on the over head lights come on and go off once either door has been closed. We scanned the car and shows no faults. Any suggestions would be appreciated.
Thanks in advance

 

Hello Rck ... The light/s work as you say when the ignition is turned on & I presume they work when your driving if you press the overhead button, have you made certain you have not turned this off at the button, one way of knowing is the button illuminates brighter this will indicate its in the right setting, if not then press it & see. Im not douthing you but only making sure. you say they work even when the doors are opened & closed when the ignition is on so you can eliminate any other switch faulty at the doors, it sounds like the overhead switch is faulty. let us know if the overhead switch is brighter meaning its in function you need it if so then lets see if we can rectify this problem ...

 

Thanks for your response Rico. The switch does not get brighter until I turn on the ignition and then the interior lights go on.
Without the ignition on the switch is non functional and the interior lights do not come on. With the ignition on the switch functions properly. When I switch the right or left side map lights on with the ignition off they function properly. The red lights on the edge of the door panels and the mirror puddle lights also light up when I open either door with the ignition off. Any other suggestions are much appreciated.
Thanks Rick

 

It seems your switch is faulty, the switch for the courtesy light is on or off only a 1 way switch & can be replaced quite easy, Im not sure if these can be bought separately or not, I can find out for you in the morning, if not then its going to have to be the whole panel, but you can pick one up from ebay or a place like that even if its the wrong colour just swop the insides over ... send me a pic or 2 of the overhead panel, 1 with the engine running & 1 without both with the doors closed ...

 

Ignition on


Ignition off

 

Ignition on doors closed

 

Thank you for that, if Im seeing this right with the engine running & the doors closed the switch light is illuminated & with the engine off the switch is not illuminating ...

If this is the case then its showing the switch is in the on position & then should turn on the curtercy light on when the door/s are opened, but you say this is not happening, right back to the drawing board as they say, let me look into this ...

 

Are you able to remove the panel ... Im not 100% sure on the GTC how it comes off but from the pics it may be the same way as the GT, you going to have to remove the 2 black circles that look like speakers, one a mic for the phone & the other is a dummy, there are to bolts (torque) remove them and slide the panel forwards towards the screen, then you going to need a circuit tester to test the power going into the switch & out ...
If I have any pics I'll post them for you ... if not then I'll remove mine tomorrow all being well take some pics what to test & post them ...

 

Rico I have to wait for my Bentley tech to do that. Hopefully I am able to buy the switch separately if found defective. It must have two
different circuits one with ignition on and one with the ignition off. Maybe the interior lights off timer burned out and not allowing the lights to come on without the ignition on.

 

No the indicator is fine, the fault lies in the switch, sure let me know if your chap needs any info I'm always around not on my laptop but on the phone & can get to a laptop ... hope you get it fixed mate ...

If the switch is not available separate then look for a unit (panel) on-line plenty around then get your chap to swop the bits over so you can use your own
panel ...

 

Rico thanks for your assistance.
Rick

 

Your welcome Rick ...

 

Called our local Bentley dealer and he told me that you have to purchase the complete unit as the switch is not available separately and the price is north of 2000.00 USD funds.

 

Doesn't surprise me Rick, look for a unit on-line ie ebay you can find one for a couple of hundred dollars, what year is your GTC I'll see if I can locate one, even if its a different colour your chap can change the inner module over ...

 

My Bentley GTC is registered as a 2013. Production date is 10/2012.
Thanks Rico
