I keep the twlight sentinel off. In the last couple of months at dusk "headlamps suggested" will come on but will go off after 5 seconds. I can manually put on the headlights but the dash lights (and lights in the window buttons) won't go on. If it is already dark when I start the car there is no problem. When the problem appears after dusk, I have to let the car sit, turned off approximately 10 minutes and hope the problem does not reappear. Any suggestions? Is it the light sensor in the dash or a computer module or what? Thanks
