I have been wanting to convert my wipers to electric for a long time my pass has not worked for years and it finally started leaking so conversion on.
I have seen a few on here and they have did a good job of it but I think people need more details. So after 3 days of rev eng and cad I have chosen a design
that I think most diy can do. I will post part# and drawings as I go, just bear with me it is summer and I have a lot of camping to do so I might not get this done till fall. this  is my first post so please bare with me. this is not a post about air verses electric this is for the diy people how wants eletric. the design I chose uses 3 x 3 x.125 box tubbing 13" long

    Hey, EE, looks like you have a good setup but do you need the rigidity of a 1/8th" thick square tube?   I'd think a thinner "U" (3" X 1/4" x .074 thick) would be plenty and it would save "lots" of weight.

when its a done it will be swiss cheese  I used the box because it is easy to get for every one and the box make it easy for drill press work
my design I had that liked the best and was the lightest the diy would have to outsource it all and I just wanted to keep it simple  for everyone

Everyday when I look at the wiper set up on my Humvee's it sure seems like those would work on a bus without much work involved

new wiper motor
the old wiper was all most froze up in the pivot and had broken the pivot of from the bracket I had to tack weld it back on to rev eng

doublee

cut out old pivot and removed bushings and seal decided it was to rusty to reuse and made a new stainless one and ordered new rulan bushing and square o-ring  from McMaster-carr will be here tomorrow I may need to make a new shaft but that will have to wait

doublee

here is the 3" box tubing housing had to weld in a pc of 1 x 1 3/4 x 4" angle to support pivot. tubing  still needs more trimming after seeing it machined

 well it was going to good I did not realize that I grabbed the drivers side model when I programmed the mill I have been working on the pass side.
so it looks like I will be making the pass side next week. I wasn't going to do the driver side until I winterized it and could pull it out and make sure it was a mirror image.

new bushings are here they will work just fine  the head is about .025 thinner than the brass one but should work all the same I ordered longer ones because of the material I went with and my shafts had some wear on them
