2008 Grand Prix . High beams work but running lights won't come on. Fuses are good , bulbs seem good . If one bulb is bad will this cause both not to work? Or is there something else to look for?
I notice that I get less gas mileage and I have to slow down in inclement weather. My brakes feel weird, even though I have brakes.
A month ago my car started making vibration noise right below the driver side mainly when I sit at stoplight for a few seconds. Also lately my temperature gage rises a lot when I'm going slow or sitting in it after been driving it. Once I turn my heater on it doesn't really rise. Than a couple weeks ago when I start my car I can hear a kind of like a vibration sound by the transmission area. Ahhh plz help me with my car. Any info.
