What length of wiper blades should I have on my truck ?? My wipers always hit the wiper cowl and are scratching it all up .. I replaced them cuz they were worn out with the same size that were on there but I think the previous owner might have put the wrong size on and there too long.. I dont remember now but Im pretty sure I put 14" on both sides .. is that correct ??? Ive tried to adjust the arm so it sits higher but it always seems to hit at the bottom .. its weird... sometimes it does and sometiems it doesnt

 

yehh okay I think it was 18 inchs that I put on there .. I just foudn it odd cuz my old Cavalier had 2 diff sizes but oh well .. any ideas on how to fix this problem ????

 

From the cowl, there are two circular ***** the arms attach to. Remove the wiper arms by pulling out a small metal tab, and them lift the arms up and off the rotation *****. Then put them back on a slightly different angle, so they don't hit any more.

 

Get 20's

Thats what i got.

 

20's must come awfully close to hitting the top edge of your windshield.

 

20's fit fine, they don't hit the top

 

22s hit


had a 22/20 setup on my ranger
