When I went to go shopping this afternoon, I discovered my car wouldn’t start. It wouldn’t even crank, which was strange since it seemed to be running fine just two days ago. At this point I assume either the battery is bad or something else is. It’s a bit hard for me to tell since the engine wouldn’t even try to turn over. Let me list out the what I’ve observed and let me know you what you think the cause may be.
When I first tried to turn the the car on it wouldn’t even turn over, in fact, all I could hear was the a fairly loud buzzing from behind the dash board. On further attempts I noticed that the info display (or whatever it’s called) wasn’t displaying the tire pressure readings. (No idea why this might be.) I did later notice some “reluctance” from the automatic door mechanism, and earlier this week I obserserved my car was a bit more reluctant than usual to start, but I assumed it was just the cold weather. After the initial attempt to get my car started, I tried jumping it, but no luck. It still wouldn’t start or even turn over. If it’s the battery, said battery must have a dead cell, however, wouldn’t the engine still try to “turn”?
I tried again this evening after it had gotten dark, since it would let me observe the headlights and such. Same behavior as before. I couldn’t really tell if lights had dimmed. HOWEVER, when I tried yet again a little later I accidentally set off the alarm. Now I observed the lights were dim and the horn weak.
Additionally, when I turned the alarm off I heard that buzz behind the dash again. Most of what I’ve seen makes me lean toward the battery, but this noise bothers me and makes me wonder whether there may be some kind of electrical fault.
Other information: My car is a 2008 Saturn Aura, that I got used in Jan of 2010. I assume the battery is at least that old, since I haven’t gotten it replaced while I’ve owned it.
As things are, it looks like I’ll have to get it towed come Monday. The question is do I have them take it to the dealer or to Autozone. If I can be certain it’s the battery Autozone would be my choice, but since I was unable to successfully jump it, I can’t be sure, hence the dealer may be safer.
