Brake Light Not Working
When the brakes are pressed, one or both brake lights do not light up.
Blown Fuse
If both bulbs are inspected and neither show damage, then the next possibility is a blown or missing fuse. Inspect the fuse box and find the appropriate fuse for the brake light system. If it is missing, or the fuse is blown, replace the fuse.
Burnt Out Light Bulb
Typically both brake bulbs will not burn out simultaneously, but it can happen. To see if the bulb is burnt out, the bulb must physically be removed from the car and inspected. If the filament in the bulb is split or damaged, use this brake light replacement guide to replace brake light bulb.
Headlight Not Working
One or both headlights for the car will not turn on regardless of the switch being set to on, or it is nighttime and the automatic lights should be engaged.
Blown Fuse
Again, like the brake lights, if both bulbs are inspected and neither show damage, then the next possibility is a blown or missing fuse. Inspect the fuse box and find the appropriate fuse for the headlight system. If it is missing, or the fuse is blown, replace the fuse.
Burnt Out Light Bulb
If it is suspected a bulb is burnt out, like the tail lights, the light must be removed and checked for damage. If the bulb is damaged, use this headlight replacement guide to replace headlight bulb.
Poor Gas Mileage/Poor Engine Performance
The vehicle is experiencing noticeably poor fuel economy or abnormal engine performance, or engine air filter is visibly dirty.
Engine Air Filter May Have Surpassed Usable Life
Manufacturers recommend replacing engine air filters approximately every 60,000 miles. If experiencing less efficient fuel economy than normal, and it has been at least this long since the last air filter replacement, consider replacing the engine air filter.
Engine Air Filter Appears Dirty/Damaged
Engine air filters can hold/accumulate dirt and sometimes become damaged. Checking every 6 months and, cleaning, or replacing as needed will ensure proper performance.
Car Will not Start/Has Trouble Starting
Vehicle has difficulty starting. Visible corrosion or damage on or around the battery.
Battery Has Visible Damage/Corrosion
Excessive build-up of corrosion on battery terminals is indicative of a damaged battery in need of replacement.
Battery May Have Surpassed Usable Life
There are many different causes for a car not starting. The first place to check would be the battery. Manufacturers recommend replacing your car battery every 3-4 years, but the best way to check your battery is by using a multimeter to check the voltage output. If it is lower than normal, you will need to replace the battery.
Poor Wiper Performance
When windshield wipers are engaged, they leave streaking marks on the windshield.
Wipers Are Damaged
Damaged wipers will be apparent if/when they need to be replaced.
Wipers Have Surpassed Their Usable Life
Windshield wipers most likely need to be changed every six to twelve months depending on how heavy or light the usage is. It normally is apparent when you need to change them, as they will streak or make weird noises. Use this replacement guide to change worn wipers.
