07-08 Windshield wipers, what were they thinking

[okfoz]

I went to change my wipers and I found I have some odd clip on design that not every wiper supports..

I ended up going with Michelin because it had what I needed.

I did learn that the 09+ uses the J hook style, I was wondering if anyone has ever converted a 07/08 to the 09+ design, I would think the entire arm would require changing.

This bothered me as well when I changed mine on my 2007...such a stupid design.

There was a campaign on the 07's and early 08's...my dealer replaced the wiper arms with the newer J-hook style at no charge to me.

Seems the old style didn't tension against the glass properly which caused the blades to skip across the glass, no matter what speed the vehicle was going.

 

[okfoz]

By chance do you know the campaign number? Do you have a receipt that might show the number for it?

One thing that I have noticed, is the low profile wiper blades that are like a beam do not work worth a darn on arms designed for the wipers with the metal frame. What I found is the fact that the new beam style are lower profile and do not hold enough tension against the windshield. Consider that the old frame type have up to an extra 1/2 to 1 inch of height that is translated into less spring tension...

I have tried them and they always sucked and I swore to never go to the new style again.

x2 on Parthery's post. I changed the arms on my '07 Burb to the '09+ style J-hook arms because the original arms didn't put enough tension on the blades and they wouldn't wipe for *******. I believe I spent around $60 at the dealer for the new arms. With the replacement arms and Bosch Icon blades I'm totally satisfied.

I have a set of the new (still in the bag) style wiper arms that I'll sell you. I don't drive mine in the rain so I never swapped them out. PM me if your interested.

 

[ChrisK7UND]

@Nasty GM, Do you still have the set? What are the part numbers in them. I heard they changed the numbers from what is listed on this campaign.

Never noticed this thread. Thanks for bumping it up.

GM Parts Direct has them for just under 70 bucks shipped. As usual, their shipping charges suck, but they seem to have the exact part numbers in stock.

 

[okfoz]

The set that Nasty GM had were still the Clip-On type that are used on the Silverado and the Sierra...

I still have them and I have the clips... I am still looking for the 09-14 type with the J-hook... just easier to find new wipers for them...

 

[ChrisK7UND]

Gotcha. Yea, I may get the J hook style for my 2008 Tahoe. Although I still see new ones with the clip style. Seems weird they did the J hook campaign then still use the old clip style on the new ones.

Ok... I am not sure then because the wiper replacement book I was looking at showed that the 07-08 used the clips, and 09-14 used the J-hook type... of course it might be in error.

 

[ScubaJim]

Funny, I have an 08 Tahoe I purchased used from a dealer and it had the J-hook type already.

Question....With this service bulletin, would that mean that GM would fix this for free?? If not, what would the cost be??

 

[okfoz]

A SB is not the same as a Recall...

Service Bulletins are little notes that If it was still under warranty, they might replace it free with a complaint. After the warranty is over they do not have to do anything with a SB....

Recalls or "Safety Recalls", are when they will fix it in or out of warranty for free (usually) There can be a shelf life on recalls tho. I know for the third generation Firebird and Camaro there was a recall on the buttons for the seat belts, which the majority of which has not been repaired. Most dealerships do not honor the recalls that are so old, but if you push them sometimes they will... In the case I used, at the same time you can buy a kit for $2.00 and do it yourself in 20 min.

What I thought was funny was I had a 2005 Buick Rainier where the fuel sender went kaput and I had it fixed around 70,000 miles. (it was out of warranty obviously) Come 2012, I got a letter in the mail stating that they would replace it for free... A lot of good that did me...

What are the correct wiper arms that will fit an 07 that has the J design? Mine has the weird clip for the wiper blades. And I want to be able to buy normal J hook type wiper blades. Thanks.

 

[okfoz]

The J-hooks I think started in January of 2008... for good reason.
