The wiper's keep hitting each other and over lap. What could be wrong? I changed the wiper arm myself. I bought two 28" wipers. Should they be different lengths?
Wipers ARE NOT "DIFFERENT SIZES" in Fact they are Usually the same I have A 97 Caravan And BOTH Sides are SAME SIZE. They Must OVERLAP Each Other As to Cover Glass Completely. If your Wipers are Same As 1997 the Direction they Turn is the SAME as in (#1) FROM Left to right. (#2) Some However Go In OPPOSITE Direction SUCH AS BOTH START FROM CENTER and Travel OUTWARD Right Side Wiper going out to from center at Start and Right Direction LEFT SIDE Starts at CENTER and Travels to the LEFT. All of THAT BEING SAID SEEMS TO ME that Yours are ( #2) TYPE and When you Installed the Wiper ARM You May Have not Installed it in the EXACT POSITION as the One you Removed, They Must Be Timed. ,
The BEST WAY Is In There "PARKED" POSITION" That's when you turn them off and they seem to AUTOMATICALLY Drop Down LOW on Windshield. This is Usually When you can Time them Correctly it May take A Few Try's to Catch them Just right. JUST REMOVE the One you Replaced and Put it Back on in Slightly in Different Position . I Believe That This Is The Answer you Are Looking for Have A Great Day , Please RATE Me and Thank You Very Much
Hey, most cars have different lengths. The drivers side is usually the longer or the two, even if the car was meant to have two 28" you can get shorter ones, they will work just fine, just be sure they are as long a possible with out them hitting or going over the window.
How that help

That van takes 27" blades but you may actually need to reposition the arms back to where they should be. sometimes they get off enough to hit each other from snow or ice .. to check if they are in right place turn off wipers.. look how they lay on the glass both blades should lay horizontal.. if one is to high flip open the black cover at the base of the arm... you will see a 15mm nut under it.. loosten it enough to reposition the arm properly.. then retighten it and push the cover back down and retry the wipers
28" is the correct size, the only thing that can cause this is the wiper arms are not positioned properly, did u have them off? the other problem that will cause this is the transmission that moves the blades is loose or has worn parts.
