Wiper arm catching on itself 1984

Iím having a hard time trying to figure out what is up with my wiper arm. As you can see the angle of the blade is too steep and is causing it to sometimes catch on itself. It almost as if the lower arm is too long? If I lift the blade up 3 inches it pulls the arm to the position were it should be.

It this blade correct? Does it bow to much?

The wiper blade isnt too bent - thats how they all are.

Did your "fix" rectify the issue? It does seem like the fit isnt right...???

It looks like the spindle on the wiper end is bent, is it?

Definitely looks like someone jacked it up good when trying to fix something. A PO issue, or CO issue?

re-index the wiper up higher on the windshield so it doesn't park so low.

Remove the wiper arm.
Turn the motor on and shut it off so it is in park position.
Take a sharp pick and dig the aluminium out of the spindle splines.
Align the arm in rest position and tighten it down.

When the arm comes loose the splines on the spindle chew the mounting point of the arm filling the splines with aluminium so the arm has no bite to the spindle which causes it to slip. From the last picture those splines are gunked up.

Doing this should fix the problem, I've done it many times on all makes of cars.

You definitely need a pic of what it suppose to look like, and then you need to club the previous owner that did this.

I was talking about the other end of the wiper arm being bent, the end with the wiper blade...

I took some pics of my wiper arm. The blade is gone and needs replacing as I don't use the wiper almost at all but it should give you an idea of how mine is setup.

I just got my car back and am ready to take some pictures of the wiper arm for you. Is there anything in particular you want me to focus on, or just some pictures of the entire wiper assembly?

How high up the blade sits on the windshield. Some cars the blade hidden and other cars have a lot of the blade is exposed. And I'd like to see with the hood down and see how much space is between the hood and where the arm gets screws down.

I bought blades refills by Amco I think it to tall and is causes it to lift the arm up and catches as it goes across. I ordered a blade from a Lotus parts seller ($80) so at least Iíll know I have one perfect piece to the puzzle soon.

I ended up tracking down a new wiper arm but the wrong style was shipped. The lower arm on this one has this nub where mine should have a ring.

Lucky they had correct arm with the ring. What is interesting is the mounting holes on both arms donít have any spines. They are totally smooth? I spoke to a Lotus parts vendor and they said when it get tighten down it makes its own groves and they are called ďwitness marksĒ.

I hope this new arm works.



Also what is this little silver peg there for?

The new arm works and doesnít hit the hood. The trick was to put a pin in it to straighten the arm out and then tighten it down and removed the pin and it worked perfect. Since the previous owner had put a key in it to stop it from slipping the hole was to big so when it was tighten down it wasnít straight. So when the arm went across the windshield lower arm would catch on itself do to the angle.
