The interior light on my GU turns on and off intermittently. I'm guessing that the problem lies with one of the door switches. Is this a common problem and if so, which door is it normally? I have resorted to leaving the light switch to 'off' which means no light when opening doors.

check the rear door. mine does it all the time. Doesn't seem to close properly occasionally.

Mine did it on the small barn door so i just disconnected that one and taped up the spade connector from the switch until i got a new one.

Been a few threads around on this problem. Most common culprit (allegedly) was the large Barn door, closely followed by the small Barn door.

In my case it was the Front Pax door

my was the same, then found a crack in the large rear door, welder it back together, lights no problems now.

Would the barn door switches be the same on both the GQ and GU? If so, I might swap the switches over from my Mav before I sell it.

Tape a piece of a cardboard box over each switch until you find it.

Check each door in turn to see if you just have to push it in a bit further to operate the switch. If so, put a velcro dot on the body where the switch touches - problem solved.

I used one of those sticky pads that you place on the bottom of chair legs to stop them marking the floor, it has stayed stuck and has stopped the dreaded light flicker from the rear door switch.

It will be the large barn door guaranteed.
Had the same issue so while repairing the crack on the door I also tested the switch and found it to be the problem.
I just disconnected it why would you need it as the small door has a warning switch.
