I had a 00 GMC Sierra and a 00 S10. Both of them had the headlights that automatically came on at night, just like my Grand Prix GT I just got. But the trucks had the dome override switch, where my GP doesn't. Is there any way to get the lights to come on only with the headlamp switch? The only way I know to do this is to press your emergency brake and then start the vehicle. But it only does this during idle, which is silly. I appreciate any help or ideas.
