Courtesy lights staying on

My '91 coupe has courtesy lights staying on as of last night.
I have replaced both door switches a few years ago with no issues everything has been fine since then. I checked both door switches today and they seem to work fine. The rear hatch switch works on both doors as well.

I'm wondering about the timer that delays the interior lights turning off ?

Any suggestions would be greatly appreciated.
Thanks
Graham

1. What happens if you start the car with the doors closed, turn on the radio, turn off the car? Is the radio on at this point? Open a door. Is the radio off at this point?

2. You are 100% sure that the dimmer switch is not at the top?

I'm thinking one of two things , door lock switch as lights are supposed to come on when the key is turned to unlock ??

OR
A relay that controls the auto off of the courtesy lights when car is started or locked up ??

There may be more but that the best I can think of , just not sure how to test those functions.

BTW the feature is called DAB "Delayed Accessory Bus" by GM and that may help your searches.

I did find the problem. Funny it was in the thread you sent and I saw that after I found the problem.
Drivers side door lock cylinder was not left completely upright when key was removed. !!

Thanks
