Autex.com has many electric wiper kits and are direct replacement. Mine never worked. Plus you get motors switches and plug and play as well as intermittent. You lose a lot of airlines that leak as well as new switches that don't. :) Took us about an hour to pull all the old stuff and put in the new ones.

I changed my 2 air wiper motors to 2 electric motors. It was the best thing to do. Even though there are two separate motors, the electronic controls keep them in synch. Now I have infinite variable intermittant speed plus low and high. Best conversion yet. Good Luck, TomC

Don't see anything on their website for GM buses. That's the problem I have seen elsewhere - lots for MCI and Eagle, but not GM.

That's  what I've  been saying for the last couple of years. Nothing for GM Buffaloes!If they were similiar as MCI or Eagle, they would offer a kit.

 NLC-GM-EAG-002     GMC 4104, 4106 Buses  can use this EAG002 model, But must be lightly modified to fit...    $895.00
These are the ones but need a little moding.

You do a lot better on price using electric wipers from a Blue Bird school bus and you don't need a degree in heart surgery to do it.Air wipers work good if maintained lot of the newer buses offer both air or electric.the electric wipers cost less I saw the air wipers were $700 more expensive for a upgrade or down grade which ever you choose to call it

This is where he bought the motors and arms. Made a mounting plate to mount them. He commented that he swapped the arm return springs for heavier ones from a Ford pickup.

Certainly something to stick in my file for the future, but it seems that right now all I need to do is swap the two valves and replace a few feet of air lines. Much easier than fabricating new wiper motor mounts.

The air wipers work well, have infinite variable speed, and should outlast me.

They last a long time the regulator goes bad then they start slapping and don't have a constant speed when the air presuure goes up or down,the air wipers usually don't give you problems LOL I can see Daves not working it rains very little where his bus lived

And 1979 probably could use a complete rebuild. They probably have a recommended service like other items.

Maybe so, but not right now. I talked with Luke about it, and he said that he didn't see any sign of a problem with the wiper motors themselves, just the valves. Only 47,000 miles on the bus total. I know that seals dry out, but it's not on my short list. I even asked Luke about getting a rebuild kit to have on hand just in case, and he didn't see any reason.

Air wipers are very good, and are easy to fix.

Actually Richard, I wasn't referring to yours, as they should be in decent shape.

Luke is doing you a favor you never know what kit you will need till you remove the wiper motor anyways GM did some crazy stuff,that really pissies you off  when you buy a kit and year later find out it's the wrong kit BTDT

When I took mine out many years ago the valves on the back literally felll apart. They were some kind of composite. I got new ones and new o rings from Luke. Put it all back to together with the air lube etc and they worked for another year and then started slapping the center bar. Pulled them out took them apart and cleaned and lubed again. worked for 3 months and yes we did use them especially in the Tahachapie Mountains as well as the coastal runs with all the wet fog.
I pulled them out and sold them put in the electrics and they work great. Have not touched them in 8 years.
