Winter can be incredibly hard on your vehicle, so there are things you'll need to do to take care of your car once spring rolls around again.
First of all, you should replace your windshield wiper blades. They've likely gotten a lot of use during the winter, so they probably aren't in great condition. You should also check your windshield washer fluid, even though you probably won't need it as much during the spring.
Next, check your suspension. Not only are potholes a lot more common in the spring, but months of driving over snowy and icy roads may have done more damage to your suspension than you might think.
Finally, check your tires and consider replacing them. If you've been driving with snow tires, you can swap them out with a regular set. If you don't have snow tires, you should check to make sure that your all-season tires still have plenty of tread and are properly inflated.
