Check battery terminals and lights
"Many electrical issues and ignition problems stem from loose or corroded battery connections," says Travers. "If you notice corrosion on the posts or cable connectors, use an appropriate brush ($4 per brush.) This is a very inexpensive, yet handy tool that you can get at any auto parts store. And clean both (posts) completely, and then reconnect everything snuggly and securely."
As part of regular car maintenance, and for safety, make sure all of the car's lights are working; it's important for you to see, as well as be seen, during autumn's longer and darker nights, adds Molla. "Replacement bulbs will typically cost a dollar or two, with the exception of headlight bulbs, of course. They're considerably more expensive, but you can replace them all quite easily on your own without tools and save yourself a hefty labor charge in the process."
Headlight bulbs range in price from $14 to $27 for a single bulb to $25 to $50 for a dual pack.
