I am trying to remove my wiper arms but they are stuck on their shaft. How can I get them off? I've pulled on them so hard, they feel like theyre about to break.

 

There is a puller GM specifies but you should be able to get them off without it. From the manual:



Removal Procedure

1] Raise the hood.

2] Turn the ignition switch to the ACCY position.

3] Turn the wiper switch to the DELAY position.

4] Turn the ignition switch OFF when the wiper arms are in the innerwipe position and not moving.

5] Place a piece of masking tape (5) onto the windshield at the tip of each wiper blade (6) to aid in the wiper arm reinstallation.

6] Disconnect the washer hose (3) from the air inlet screen.

7] Remove the wiper arm nut cover (1).

8] Remove the wiper arm nut (2).

9] Using the J 39822 , remove the wiper arm from the wiper transmission.

10] Remove the wiper blade from the wiper arm.

Installation Procedure

1] Install the wiper blade onto the wiper arm. Refer to Wiper Arm Blade Replacement .

2] Position the tip of the wiper blade (6) to the marks made on the windshield with masking tape (5).

3] Install the wiper arm onto the wiper transmission (4).

4] Install the wiper arm nut (2). Tighten the nut to 25 N·m (18 lb ft).

5] Install the wiper arm nut cover (1).

6] Connect the washer hose (3) to the air inlet screen.

7] Remove the masking tape (5) from the windshield.

8] Inspect the wipers for proper operation.

 

Got em!

Just when i was going to give up... i thought id give em one last tug. So i rocked them in the direction they go in when working and in the opposite direction... and you hear a click. At that point they're free and you can pull them right up.

Now i just gota get the motor out and get to the circuit board.
Here are the pics of the cowl area after removal:










Hope this helps some of the other people who were trying to remove the arms themselves.

 

hey dude. this does help me. i've been trying to remove mine to get the damn possesed wiper motor out to replace it. it goes on when ever it wants to and i've cleaned the utters out and everything but it looks like it's to far gone. hope i can get em off like you did. thanks.

Yea, I took mine off for the EXACT same reason. Total BS in my opinion that there isnt a recall on the sh*ty wiper system. I'm replacing the motor circuit board this week hopefully. I kept putting it off because i couldnt get the wiper arms off. If you have questions, pm me.

 

i am trying to do this right now, but i cant get my wipers to move at all, i hope this is possible when in the lowest position....

 

Mine were in the lowest position, so I just PULLED them (in the direction when working) and both wipers moved up to a middle position (pointing towards the top of the passenger side A-pillar). Then you have to try to pull the away from the windshield while rocking them in the two directions wipers move in when working right. Hope this helps.

 

I will go try this now, and btw I just pmed you, so you can ignore that! Thanks.

 

i got em! thank you!

 

Awesome! Pulling those suckers off made my weekend LOL.

Btw, for others with same problem... mine were originally in the lowest position, so I just PULLED them (in the direction when working) and both wipers moved up to a middle position (pointing towards the top of the passenger side A-pillar). Then you have to try to pull the away from the windshield while rocking them in the two directions wipers move in when working right. Hope this helps.

Hope this helps.. btw, the circuit board is in the black box right next to the motor. Ill take pics when i replace the board this week.

 

im replacing the whole unit. I am just having trouble putting it all back together! When putting everything else onto the motor I can't get it to wipe correctly.

 

Yea, it looks like putting it back together would be a pain. I tried to take a lot of pics so I'd know exactly how to piece it back together. my advice is to readjust everything if youre not wiping the windshield properly.

 

I don't know exactly how to hook up all the linkage to the motor. I am not sure exactly what direction to put them in... I gotta keep messing with it, what a pain... Chevy should be fixing this for free!!

 

Im totally with you on that.. this should be a recall. BUT if you do need some detailed pics of the wiper setup i can take them for you too.

 

That would be great! I need to know what direction to connect the linkage to the top of the motor.

 

GTSLN97,
I am going to replace my board today after work, so i will take pics for you then and post them up for you asap.

 

I figured it out last night. Thanks and good luck.

 

Nice. I got mine to work today too. I just replaced the wiper motor circuit board ($100 from dealer) and tested it 15 minutes ago. Now im going to go find the best sealant known to man so I dont have to deal with this again. Here is the board I pulled out...

 

The wiper motor is 40.00 at auto zone and this is the same mfg that supplies gm with a direct replacement. I am going to add insurance by using a rubberized paint, material used for gripe on handles, and cover the entire assembled unit to reduce future problems with water.
