XC90 Windshield Wiper Arm Assembly Installation Topic is solved

[MoVolvos]

.
The 2012 SUV was purchased with the driver's side arm not moving. It snapped but not sure how that could have happened though I haven't thought to check the hood. Perhaps someone was upset .

1) Removed cowl cover which was pretty straight forward.
2) Needed a wiper arm removal tool as there was a lot of oxidation on both attachment points.
3) Reused old motor and arm so I didn't have to mark and test the assembly position.
4) Reused another longer arm as the metal was thicker as with the entire old assembly vs new.
5) Reused the 2 old grommets as they felt like neoprene rather than rubber. The new large rubber mount was used instead of the old.
6) Grease the old motor gear and worm drive. There was very little grease inside so just squeeze some silicone grease in the gaps.

(EDIT: Per chiTownV's inquiry the cowl area, it was vacuumed, dusted, wiped and for good measure compressed aired of dust and debris besides clearing the drain lines.

It looks like you missed one of the most important things while in there. To clear out the drains to prevent water from damaging the CEM.

Vacuumed, brushed, wiped and compressed air hosed everything just in case and please do not critique on the merits of which should be done first. I'm sure many won't have to go to that length in cleaning the area.

No need and best not to assume you know when I took the picture. It's also best as a courtesy and good forum etiquette to ask if I'd cleared the drains rather than assume you know I didn't.

Whoa. No need to be sensitive about it. You can just say if you did. Just going by the pics you posted and that you didn’t mention it. The drains are vital maintenance and it’s exposed if doing this work. No assumptions, simply going by what you posted. No need to make assumptions that I assumed.

Clearing the drains is something to mention while in there if posting a guide for all to see. It’s good information for new XC90 owners who may not know to clear the cowl drains as it can lead to the XC90 not operating and a significant CEM cost. Not exactly a small thing.

Btw, how many miles have you now accumulated on your new-to-you 2-3 month old XC90?

With the photo of the broken assembly still in the car you should assume correct I have not had a chance cleaned it. You can assume I might, just might not have cleaned it if the new assembly was in there. As mentioned best to asked rather than assume I didn't do it. Best to assume the better of others abilities rather than stating your assumptions of their ignorance. Makes for polite and courteous conversations.

Yes, every car has drains in the cowl not just the XC90. As for pointing out my not having experience, as in other posts, due to so little time with the XC90, yes and no, but I have MVS and other forums with many many experts to help when seeking it.

Per my previous statement in another forum, I won't be replying due to the weariness of having to clarify your assumptions and not so constructive method of helping with the addition of the never ending what if's.

All you have to do is say you cleaned them. That’s all. Again, no need to be so sensitive.

No need to get bent over when anyone on the forum makes a comment on what you posted. Forum members can make comments, especially when it’s a vital preventative maintenance item.

Mentioning the cowl drains, that were not part of the initial post, can help others who are not aware the cowl drains should be cleaned. Clogged cowl drains could lead to water getting into the CEM.

If one sees leaves and debris under the cowl, like the pictures in this thread, clean them out. Simple as that.

Cheers

I have been made aware I should apologize to chiTownV and MVS members for participating in this kind of unfruitful discourse. I was also made aware to look on the bright side as there was only one wrongful assumption of not doing the "most important things" in the replacement work, which meant overall the work was done well without issue.

I had added chiTownV's inquiry of the work not done in the original post. I will leave it up to the Moderators whether to delete these unfruitful post or leave them as an example of not how to conduct ourselves on MVS. Again, my apology to chiTownV and MVS members for these posts.

Here is the link to the Wiper Arm Assembly purchased. Finally installed the old wiper arms with new front FCP Bosch Wipers. I wiped the new blades with 303 Products Marine Aerospace Protectant and dry swept tested a few times to make sure the wiper arms were in the right position on the windshield. Very smooth movement even on the dry windshield test!

A bit of grace goes a long way on these forums. Not trying to pick on you chitownV, but a question comes away a bit different than a statement.

It looks like you missed one of the most important things while in there. To clear out the drains to prevent water from damaging the CEM.
