Recall - Heated Windshield Washer Fluid

[finall]

Recall - Heated Windshield Washer Fluid - 2nd recall for removal of system, since first recall did not fix the problem.

Posted this on another thread here, and on another H2 forum, but no answers... Surely there are Hummer techs out there that should know the answer to this....

So I ask you, Hummer braniacs, what to do? What actually catches on fire, a module or wiring? Can the system be simply disabled by removing ALL electrical current from the heated WW system, and just leave it in the vehicle? Does it have its own dedicated fused circuit, or not? Where is this unit located, so that I can attend to it?

I need a definitive answer, not just a guess, as this is very important. The answer to this question will undoubtedly help thousands of other H2 owners to avoid butchering of their H2 by GM.

Help Please!

Yes, that is the other thread I posted the question in, as I already mentioned in this post

There is an answer...if you're affected, the dealership will "disconnect" this feature from your truck. You'll get a $100 check from Hummer (from the dealership).

There's no fix...but the answer was in the previous post.

As I explained on the other post, and will explain here again: The "disconnect" means major surgery on your H2. It does not mean that they unplug something.

It involves GM cutting out the heated WW fluid system, and cutting the wiring harness, ww fluid tubing, etc. They do not simply disconnect it, they cut it out of the vehicle. Literally! For liability reasons....

I would prefer not to do that. It is going to be a huge mess! As you know, this is a 2nd recall for the same thing. They failed once already. Now they say, we can't fix it, so we will just remove it. I say, NO WAY, since they do not know what they are doing!

My original question above stands:

Is there a simple way to disconnect the unit form the electrical system, in such a way as to prevent it catching on fire, and yet leave it in the vehicle? If so, where is the disconnect point? What actually catches on fire, a module or wiring? Can the system be simply disabled by removing ALL electrical current from the heated WW system, and just leave it in the vehicle? Does it have its own dedicated fused circuit, or not? Where is this unit located, so that I can attend to it?


Still NO ANSWER to my question. Any GM techs out there?

Ive done a few of these recallsalready and its not a big mess. six wires cut and taped. module removed and hoses re-routed. Cant even tell hardly that it was ever there. I would recommend the dealer does it so if there was ever a probl,em and the recallwasnt done at the dealer your insurance may be void

The vehicle's harness doesn't even get cut. It's the wires that are part of the heater. There is no "major surgery" the wires are just cut and taped so the connector isn't left unplugged to get corrosion in it.

Thanks guys. That info helps.

What if I just unplugged the unit, instead of having it removed? That should have the same effect then, since there would be no power going to it, and as such, nothing could catch on fire?

I would prefer to keep the unit in the vehicle. Maybe some day there will be a proper repair for it, but by then it will have been yanked out. Maybe one day far in the future the H2 will become a collectors item, and it would be nice to have all the options intact (even if disabled).

So is there a fuse or connector that I can disconnect? I have bad experience with the dealer where they screwed up stuff, so I would prefer to do this myself....

If it just the fluid that is under recall, I will just have them replace with some autozone non heated windshield fluid

SORRY, could not resist due to the heading of the thread!

HAHA! Too funny!!

I just took mine to the dealer for warranty work and scheduled maintenance... mine doesn't have the system to begin with.... lucky but out 100 bucks!

Help Humtech!

I am going to disconnect this myself, instead of letting the dealer chop (yes, literally, they cut off the connectors and tape them) up on my Hummer.

How do you disconnect these connectors (labelled #1 and #2) ? Do you need a special tool? What do you do to get them apart (they are locked together)? I managed to pry the #2 apart, but the big #1 is a mystery.

How do you keep water off the wiring harness connector ends that stay in the vehicle? Normally when the 2 halfs are connected together, there is a water-tight seal in between. Now the exposed ends need to be wrapped in something very waterproof. I do not want to cut the connector off the end, in case some time in the future a retrofit can be done with a non-faulty heater of some sort.

I presume by disconnecting these, that the heated WW pump can't burn down the H2?

[HUMTECH]

Squeeze the tab down on the big two wire and pull. Same with the small one. Just take a close look and its obvious.

[finall]

Thanks Humtech for the clarification.

I am also removing the large 60 amp fuse, located underneath the plastic cover surrounding the fuse box. to prevent any "incidents" with the heated WW fluid pump.

For everyone else to know: The fuse for the heated WW fluid pump is hidden underneath this plastic valence panel, and is situated low between the panel and the battery. Unclip and pull straight up on the plastic surround, to lift off this cover off the fuse panel. You will see the large 60amp fuse sitting next to the fuse panel.

That should do it I believe.

Is there a problem with other GM vehicles with heated windshield washer fluid? I'd assume alot of the parts are the same, especially with the cadillac escalade, tahoe, etc etc

[finall]

Yes, all of them that use the same Heated WW system have been recalled.
