How to remove the wiper arm on a 1966 Catalina. Please don't tell me to pull up the plastic tab and remove the nut. These don't have the plastic covers and I can't get the metal off to see if there is a nut or not holding it on. In fact there is a second support arm running under the main arm.

To access the wiper, remove plastic cover. Remove nut on wiper arm. Carefully pull off wiper arm. Replace with new wiper assembly. Remember where wiper arm was and reposition it. Put nut on and tighten. Do not over tighten. put plastic cover on and your done.

the nozzles just snap in from the top.... you first pop the cover at the pivot point of the wiper arm to access the nut. remove said nut. remove the wiper arms (a puller is very useful to avoid damage) , then Remove the air inlet grille panel (held in with pushpins and small 1/4in or 9/32in bolts. disconnect the hoses and squeeze the two tabs that hold them in. because they snap in from the top, i have seen people crush and brake their old nozzles with needle nose pliers. pull the hose through the hole and attach it to the new nozzle...... NOT the recommended procedure, rent or buy a puller that looks like a small two jaw gear puller to save yourself a big headache (mine was only $45). good luck

There are two main styles. One style has a nut covered by a piece of plastic at the pivot point, the other style is a metal retainer under the wiper arm.
The style with the nut is most common. remove the plastic cover by prying it up at the pivot area, remove the nut underneath, usually 13,14 or 15 mm. then life the wiper off of the glass and wiggle off of the shaft.
The retainer style you need to lift the wiper off of the glass and look for a small metal tab near the point where the wiper pivots to lift it off of the glass. then pry the tab gently outward. This releases the arm from the shaft. Just wiggle it free.

At the base of the wiper arm there will be a plastic cover. Pull up on it an you will see a nut that holds the wiper arm to the post. Remove the nut and push down/up on the wiper arm to release it from the post. Once both wiper arms are removed you can remove the push pins that hold the cowl in place and remove the cowl. You will then have access to the wiper motor and linkages.

pull the wiper arm up, pull the wiper back then pull it hard down the wiper arm once the loop releases the wiper.

if there is a nut in the middle at the base of the arm remove the nut if there is no nut then lift the wiper arm away from the window and you will see a small tab that will pull away from the base of the arm pull this away and hold it while you let the wiper back down the wiper will hold the arm up and lock the tab out now gently pry or pull the arm off

I had the exact same problem with my 2000 buick century which i also bought used and after asking GM what it could possibly be they told me it was the whole wiper arm assembly which would be over $700 to replace. I decided to have a look myself and discovered that a small metal tab which makes the wipers park was bent and the mechanism was not engaging after turning the wipers off. i simply bent the tab back carefully and they parked again, saving me hundreds and it took about 15 minutes.

Open the hood and look where the wiper arms attach to the spindle. remove the caps covering the nuts, then remove the nuts. the hardest part here is most likely going to be getting those arms off. then remove the plastic grille under the right wiper arm (driver's side).

When you can get at the motor assembly, turn the wipers on and off and watch how it assembly operates and see if you can find the tab. This is the best picture i could find with google.


Once i found the tab i took a large flat head screwdriver and tapped it gently with a hammer to bend the tab back. you can tell when you turn the wipers on and off that they park properly. When it came time to put the wiper arms back onto the spindles i set them where they would be when turned off (resting in the plastic cradle at the lowest position).

I hope this was helpful. i know it was for me.

Do you mean the wiper blade or the wiper arm?

The wiper blade should have a small tab or lever on the underside of the hinge where it attaches to the arm. Use a small screwdriver or a pick (etc..) to gently pry the lever upwards to pull the locking tab out of its corresponding hole on the wiper arm. Once the tab is up, firmly grasp the wiper blade and pull towards the base of the wiper arm. Sometimes they stick a little, just be careful not to bend the wiper arm.
If you are looking to remove the wiper arm, remove the plastic cap at the base of the wiper arm to gain access to the nut below. Using either a 13mm (1/2 inch) or 15mm socket (depending on the model) remove the nut by turning counter-clockwise. Once the nut is off, place your hand in the middle portion of the wiper arm and firmly push downward, being careful not to bend the arm. What you are trying to do is rock the arm off of the wiper motor stud. Be sure to mark where the wiper blade rests on the windshield before removing it, so you can reassemble it in the same spot when you put it back together. Use a grease pencil or something else that you can clean off later.
Hope this helps!
