I know this question has been asked to death and yes i have asked it myself in a thread.But considering all the little problems ive been having/and correcting on this 97 grandprix GT and the fact that i am kinda conservative in nature i need to ask one more time for piece of mind.I understand that the headlights generally run all the time when the car is started.And from my understanding is that turning the knob on the left(the one that says off and has the P with lines and the lightbulb)does absolutely nothing.Which to me makes no sense,why would i even have this knob/switch if it does nothing?I keep the knob on off all the time and my headlights,both running lights,interior dash lights,including heater control lights all stay on when the car is running.So basically all these lights stay on day or night makes me wonder if this doesnt burn out lightbulbs sooner.Its just hard to think there isnt someway to have the dashlights and or the running lights off during the day.
