H3 Safety Recall HVAC - Letter Attached

[H32NV]

First off, I am hoping that this is the correct place to put this thread. I have another thread going about a home remedy to the seemingly more frequent "melting HVAC Resistor Connector" issue on our H3's, but this is an official Recall Letter so here goes. (I tried looking for a place specific to official recalls/TSB's, sorry moderators, will comply on request).

Basically, one year ago I received a recall letter from GM which explained the HVAC connector and harness issue(gets hot, melts, and fails), and in the letter it explained that they wanted to replace the connector and harness on all affected vehicles, but that they had no parts to do so at the time.

Now they have the parts.

"This notice is sent to you in accordance with the National Traffic and Motor Vehicle Safety Act. Previously you were informed that your 2007 model Hummer H3 was involved in GM recall 15042. General Motors has decided that a defect which relates to Motor Vehicle Safety exists in certain 2007 model year Hummer H3 Vehicles. As a result, GM is conducting a safety recall. We apologize for this inconvenience. However, we are concerned about your safety and continued satisfaction with our products.

IMPORTANT: Your Vehicle is involved in GM Safety Recall 15042. Schedule an appointment with your General Motors Dealer. This service will be provided to you at no charge.

Why is your vehicle being serviced? - The connector module that controls the blower motor speed in the heat/vent/air-conditioning(HVAC) system may overheat under extended operational periods at high and medium-high blower speeds. If this condition occurs, there is risk that the heat generated could melt the plastic surrounding the connector, which increases the risk of a fire.

What will we do? - Your General Motors dealer will replace the female connector and harness. This service will be performed at no charge. Because of service scheduling requirements, it is likely that your dealer will need your vehicle longer than the actual service correction time of 25 minutes.

What should you do? - You should contact your General Motors dealer to arrange a service appointment as soon as possible.

Did you already pay for this repair? - If you have paid for the recall condition, please complete the enclosed reimbursement form and present it to your dealer with all required documents. ..... Mail us if they dont comply...

I got mine yesterday. Now to determine when I take it to the dealer to be fixed and see if I can trust them to work on my rig. I do not trust dealers and my h3 is far from stock electrically.

I got my letter two weeks ago. Dad got his on Friday. His got fixed today.

I called the dealership today to schedule mine. Apparently this item needs to be ordered at most of the dealerships before it can be installed.

They took about two hours to fix mine and they forgot to reattach the glove box retainer cord lol

I got mine and at brought up the recall to my parents...they asked if this part that needed the recall was even still on the hummer? lol I gotta decide what to do...Every time I bring the damn thing into a dealership it ends up with more problems then it went in for. Last time I went in for something simple, brakes or oil change? I cant remember, well sure enough I started getting crazy CELs and they fried my PCM back when the 5 cyl was still in the truck. Havent been to a dealership since...and its easy to justify why things "went wrong" on mine since none of its factory.

After mine was replaced, it (the blower motor I guess,) starts to buzz on settings 1 and 2...

Mind you, it overheated the day before I took the truck in, which was a week before the letters were sent out in Canada (25 Feb, 2016)...I got the only part before it had to be ordered.

I also received a letter a few days ago. My appointment is Friday @10:30am. I'll report back on how it goes.

Chris you need to video your truck pulling up to the dealership , we all want to see the looks on their faces when Squeaky rolls in. It would be fun to see just how many techs come over to look at Franken3 and see what they say when you aren't around . Keep up the great work.

Mine went out 2 weeks ago(before parts were available) so I will just submit for reimbursement. I ended up using the dorman resistor kit which includes a new harness.

Keep a dashcam rolling! I'd pay a dollar to see what they say.

I received the letter last week, so I will make an appointment and hopefully bring it in to a GM dealership next week.

My harness melted a long time ago. I fixed it by soldering the connection and it's worked great ever since. No need to take it in.

6 weeks or more and I finally got the part. They never called me so I went back in after asking them to order it and somehow it never was ordered, grrrrr
Took hour and half to get it installed.

Here is the old one. I was just starting to get some heat browning one contact.
Interesting where some of these parts come from on our "American made" vehicle.







They called me back to ask about the hood louver. Obviously, or so I thought, four SS bolts holding on my handles was a solution.
It has been on my Onstar report for years. I told them I fixed that before the recall.

This place just expanded to huge but still personal service. A couple of new techs, Jeep guys were asking me about my mods and so it goes we had a photo viewing and discussion. ha ha
It's like asking about your grandchild and you must show pictures, right?

Slovenia? Interesting.

I'd love to see pics of the new parts next to the old parts. From what was posted on "another" site, the new resistor is much larger than the old one. It was explained that the original smaller resistor generated a lot of heat at lower fan settings. That heat in turn weakened the spring contacts in the connector. Then, when the fan was used at the higher speeds, the higher amperage would arc due to the weakened contacts. Supposedly, the new, larger resistor generates much less heat, and in turn does not weaken the contacts in the connector.

Yea me too the service writer was a little slow taking me back there and the new one was already in.
I guess I could check back and see if they have another one.

I had both of my H3's done last week. I had experienced no problem but just yesterday my buddy had the exact problem described in the HUMMER recall with his '09 2500 HD CHEVY! Wonder how many other GM vehicles have the same potential problem. I am certainly going to have my '09 YUKON DENALI checked out.

No recall here in Doha, does anyone have a link to where I could buy this myself?

Took about 30 min to perform the service at Bozarth near Lone Tree, CO. Great service shop, not trying to up-sell too much. It would be a good assumption to suggest that this same harness and electrical circuit design was used on other GM vehicles such as the 2500 as noted above. I'd think it is identical to the Colorado/Canyon of the same generation as well.

Called our GM dealer yesterday and asked about recall 15042.
The man had no idea what I was talking about.
It worries me because Hummer is already a dead brand here, they've stopped stocking up on parts, even rear brake pads aren't available and must be ordered upon request. They're just offering whats still in stock.

If anyone could find out what the new HVAC replacement part numbers are, I'd really appreciate it.
