Windshield Wipers range of motion

[drfw]

1983 AStream model 310:

Passenger side wiper range of motion bottoms out too low.
Hits the aluminum about 3" under the windshield at the bottom of the stroke.
And of course, the wiper does not reach anywhere near 12 o'clock at the top of the stroke position.

My diagnosis is that the connecting arm that attaches the motor to the wiper assembly is too long.
I estimate that the connecting arm needs to be shortend by approx 1/2 inch.

That said, I am not entirely confident that I have figured this thing out.

Has anyone else dealt with this issue?
Thanks!

try removing the arms, turning the wipers on and then off. when it stops, replace the arms and retest.

There are adjustments on the motors themselves for where to stop the wiper arms. Mine needs to be adjusted as well I just haven't taken the time to do it.

There is some information in the forums. Try searching in the motorhome section.

Thanks for your replies.

I don't think this issue is a park position issue, as the problem occurs during normal operation. Wipers always bottoming out below the windshield on every stroke.

I have had a terrible time with attempting to remove the wiper arm.
That baby is stuck.
That said, I don't think there is any adjustability at the wiper arm like on newer Chevy trucks. It looks like there is only one way to position the wiper arm on the stud, so I can't see how removing the arm would help in adjusting the range of motion.

Check out this thread and the post by TxRaz. He describes in pretty good detail how the wipers work.

I had to use a small battery post type puller to get my wiper arms off.

Also check out this thread http://www.airforums.com/forums/f156...en-8563-2.html it has some information on adjusting the sweep of the wiper arm.

Our motorhome had a problem with the sweep as well and I adjusted mine and it helped some. I just haven't had time to get back to work on them and finish the job. I think I might have a problem with a bad diode or two.

Thanks for those links Brad.
I'll try that puller idea asap.

Frank,

The one thing I found when trying to use the puller was you have to make sure you don't slip the arms to far under the arm. Its kinda hard to explain but if you take close look at the underside of the wiper arm where it mounts on the spindle you'll see that there is only a narrow lip to fit the puller to. Hopefully this will save you some grief in pulling the arm, something I had plenty of until I figured that out!

The battery terminal puller worked great!

I removed the wiper arm and happily found that the knurled post that the wiper arm mounts on is just like the wiper post for the chev pick up that I have.

Adjusting the wiper arm position was a snap.

Thanks so much for the puller idea!!

Best to you all!

We have a 93 Land Yacht and I just got through replacing the blade assemblies, panographic arms and one of the mounting brackets and pivot arm assemblies. Got all this stuff fairly cheap from a web site called " School Buss Parts Online ". The even had an exact replacement for my washer pump motor setup. Ther's a lot of school busses built on the P30 chassis, they have a lot of parts for them!
