Ok i have a 2000 Pontiac Grand Am GT V6. Today i went out and turned the car on, and the lights all came on for a brief 5 seconds or so then they all went out and my "service vehicle soon" light came on. And i mean ALL the interior lights. My climate control lights, dash lights, shifter lights, lights on the window switches. Everything. I have never had this happen before. Ive checked almost every fuse and they are all fine. Last week the light came on and i just had a headlight out but that problem is fixed, i got a new headlight and the light went out. Now all my interior lights are out. Ugh, tried calling pontiac but they are closed until tuesday. Any help please? Thank you.
