Rear Wiper Blade Service

[sub]

Perhaps you have to remove the bolt?

Have you sourced a replacement wiper blade? It might be easier to figure out where it disconnects when you know how much is going to be replaced.

Thanks for the suggestion! I took the bolt off before posting this originally and should have share that and that’s where I stopped because it didn’t allow for any movement “off” the windshield for the arm but it does allow you to reposition the wiper (if for example it starts “drooping”). What is interesting (well I mean interesting in an very narrow way) is there seems to be a notch in the base of the arm right at the bolt that should be able to slide into space and allow the arm to lift. But it just stops after allowing the arm to rise just slightly instead of how we all think of it lifting up to allow you to easily slide on and off a new blade. What a strange thing! It’s basically the only odd thing I’ve encountered with this phenomenal rig

Good call on not forcing anything.

There’s a good chanthe manual is using the term “blade” differently than one would expect. My old Mazda CX9 wanted you to pull out the rubber blade from the rear wiper without bending the arm back or messing with the whole assembly.

Replacing the rear wiper was merely replacing the rubber blade and nothing more. In the CX9, you needed to keep the metal stiffeners but those were easily move from the old rubber blade to the new one.

Edit: don’t remove any bolts.

Thanks. Also for anyone who watches this post I will report back after the service visit on Feb 9 to provide info to everyone.

Just stumbled on this post as I'm in a similar predicament. I have a replacement blade, but haven't been able to figure out how to get the old one off. The front wipers were pretty simple to replace, but not this guy. I guess I'll watch this and wait for you to report back in a few weeks. If I figure it out, I'll post back.

Now that Rivian sells replacement wiper blades, you would think they would be able to explain how to install it. Still just a link to the manual that says nothing about how to install the rear blade.

At least we know what it looks like now.

Ooo this is big! Yay! My appointment is in a couple of week so I will report back on installation process and whether this was a defect just in case people need to be on the lookout for an issue!

I replaced the front wipers with trico ceramic blades after reading reviews here about how they're far superior to the rivian stock front wipers (here are the trico blade options - I got the silicone certamic ones)

So I decided to get the trico blade for the rear as well. I haven't put it on yet so can't vouch 100% for it, but based on how it looks - seems very similar to the rivian one, and a 3rd of the price.. Here's the trico rear blade on amazon. I'm happy with the front blades so far.

Yes a lot of blades work I have Bosch on the front those were easy to replace with no issue. The rear wiper assembly is blocking my ability to lift the arm - can you possibly send a photo of your arm lifted into the air? This thread has been trying to figure out if my assembly arm is defective because it doesn’t lift enough for me to slide the blade out. Service center told me I had to make an appt to have it looked at but it seemed so weird to me because the wiper works properly just doesn’t lift up. So if you had a pic of the arm lifted would Really appreciate it!

Mine doesn't lift much either. I didn't want to pull too hard and break it, so that's why I'm 'stuck' as well. If Rivian are now selling a replacement wiper, then hopefully they'll provide some instruction for us soon.

I have a Feb 9 appointment so I will report back on how it was solved and if needed give everyone instructions if you subscribe to this thread on how to do it.

Looks like this design and it's possible the arm has to come off the spline shaft to rotate the blade. Would seem stupid but possible.

HOW TO CHANGE YOUR REAR WIPER BLADE FROM MY RIVIAN SERVICE VISIT ON FEB 9:

1. Remove the cap at the base of the wiper arm. This is a plastic fastener so just squueze and pull it off but be gentle not to break it. This will expose the locking nut.

2. Remove the locking not and unscrew it from the wiper - place aside.

3. Pull the entire arm off the glass.

4. With the whole arm in one hand quickly jerk the blade to separate it from the arm. This requires some blunt force to do. So don't be shy.

5. Replace with Rivian Rear Wiper Blade. I do not recommend using an OTC/Online substitute because of the strange shape of the interface with the arm. You can buy these rear blades from the Rivian online shop for $30.

6. Place the arm back on and ensure it aligned level, replace the locking nut to tighten (as you all know do not overtighten it), replace the base cap covering the locking nut.

If you have any trouble just reply and I can give more feedback. The Rivian service advisor agreed this is a very strange and overly complicated design. In theory you could do this without taking the whole arm off but he agreed there is a reasonable chance of damaging the glass or the arm itself when you make the hard pull. So remove the whole arm to be safe.

Seems like a design oversight that they didn't think about how to replace the blade while it's mounted on the vehicle. That being said, I don't think there is any reason to "jerk" it, I was able to unlatch the blade pretty easily by turning it like the above video, but there just isn't enough clearance to turn it enough and free it from the arm.

Yeah...the rear wiper design is not a good one....just spent a bunch of time trying to figure it out. This post helped. Front wipers...a piece of cake to change.
