Turn on the rear defogger grid and touch the glass to feel if it is heating. Briefly check the wiper blades while you inspect the windshield for chips or cracks.
New blades are a good indication of a well-kept car.
Check the windshield wiper and washer operation too, and check the rear wipers and washers on SUVs, station wagons and hatchbacks. Inc. All rights reserved.
