Modern cars don't have air or vacuum wipers anymore.
And your point? Airplanes still use Magnetos and vacuum powered flight instruments so they will still function after a complete electrical failure. The most common failure ive seen in vehicles is electrical, and on road trips its common to
My point is if you're choosing between a replacement air motor and a replacement electric motor I would choose electric all other things being equal. If the electric motor requires reworking the rest of the system air may still make sense. There has to be a good reason they don't use air or vacuum on modern vehicles.
I'm not old enough to have driven or ever been in a vehicle that had I knew didn't have electric wipers. (One exception was an old truck that the vacuum wiper didn't work anyhow.)
If the battery or alternator fails your headlights won't work anyhow and you should stop driving. Most all states now have laws requiring headlights when wipers are necessary. There are a lot more people here asking how to fix or replace air wipers than asking how to fix electric wipers.
