Just went to napa and picked up a set of 17" wiper blades for my 92 4runner, get home and they look totally different. Ive never changed wiper blades before but, the kind on the 4runner has a pin, and the new ones from napa has a clamp type attachment. Did i just buy the wrong blades or am i completely stupid and cant figure out how to change them.

 

Look in the package. Did the wiper come with any adapters. Most do. There should be directions how how the mount to different vehicles.

Hope this helps.

 

They just sold me two whole wiper blades, nothing else inside the package.

 

i forget what size they're supposed to be but yeah look it up online, in the book at the store, or in one of those little computer things. The size isn't that critical as long as they don't hit anything. Infact a lot of "winter wipers" are slightly shorter than the normal wipers so that the motors can handle the heavier load for those of us too lazy to brush off the windshield.

pretty much every wiper i've seen is universal, and comes with an adapter so that they can work with any of the many styles of wiper arm

edit: you posted while i was typing.

they should pop open the little things and then slide into place, and snap the thing back shut. there are usually instructions on the back of the box with pictures...

 

our blades are 17"

 

i buy mine from wallmart, and the cheapest ones work the best.
they're 1.98 or close, and are the bottom of the barrel, but dont streak or smear

they are basically the best ive ever used, and ive bought the very expensive ones. so, now, i buy a couple sets at a time.
if i ever see a streak, or a smear, i just swap em out.
but sofar, they last long too.

 

Our NAPA shop has Nippondenso wipers guarantee fit.Might have to ask the salesclerk for some.

 

The only one I've had trouble finding is a replacement for the rear. Most are too long, like the Bosch that most carry. Being too long, there's not enough down force to make complete contact with the window from one end to the other.
