If you said windshield wipers, you're right.
Most people wait far too long to replace wipers.
They should be replaced at least once year regardless of how often they are used. If you are going somewhere warm on your trip, you're going to want your car's air conditioning system to be working properly. The two most common problems with vehicle air conditioning are refrigerant leaks and inoperative compressors. If you think your system is not cooling off the car like it used to, take your car to a mechanic to have it inspected. Pop open the hood of your car and check your air filter.
