My Miata's windshield wipers are in sad shape, so I need to replace them this weekend. How often do you replace wipers? Is it on a schedule or just when they stop working well?
There probably is a schedule for when you should change them, but I usually just change them whenever they stop working. This usually occurs when it it pouring down rain.
I need to replace my passenger side because it ripped recently, I just keep forgetting, that is until it rains and it is flopping all over. I don't change them on a schedule, just whenever I need to.
I replaced mine not to long ago because they were really old and stopped doing their job as they're supposed to. It's the first time I change them, now I'll wait and see how long they last.
