Check your fuse.
The fuse probably blew that controls the dashboard lights.
it would be great to know..
Bad fuse
a fuse
The Grand Prix models come with daytime running lights so they are on during the day, but the regular lights are controlled by a sensor and are set to come on in dusk conditions automatically and off when daylight is sufficient.
look for a blown in line fuse, 3 prong red box by back lights.
I had a similar problem with a Pontiac some years back. It was a bad dashboard ground. It may not be it, but I would start there.
did you check the fuse?
Check the bulbs they are double filamented with the smaller for stop and turn signals
No.
Hello. I had a 1987 Pontiac Grand Am and the fuse panel was underneath the dashboard. It had a little clip on it that you had to turn and the door would come open and the fuse box was right there. Good Luck! It's really kinda dumb, took me forever to find it, open the drivers door and look on the side of the dashboard.
You need a new fuse
