CARTBRY

That is exactly my concern as well. One of these days I'm going to get fed up and just do it and risk the cost of a new module if I break the whole thing. I feel that day coming soon which is why I made the post today in a last ditch effort. Somebody talk me back from or over the ledge! haha .... When the day comes and I do it, I'll be sure to update this post on the success/failure.

I have had the same problem with my 2013 Limited for about a year now. I have narrowed the issue to the physical blower fan increase (+) button below the round volume dial (not the LCD touchscreen or steering wheel controlled dash blower + button). It will intermediately act as if someone is pushing the button repeatedly. To stop it, I have to push the physical blower fan decrease (-) button at least once. This stops it for a random period of time (seconds, minutes, even the remainder of my trip sometimes) then it starts again. Pushing the LCD blower decrease (-) or the steering wheel blower decrease (-) button does not stop it, rather just fights the malfunctioning button back and forth. It's to the point where I drive with one finger on the blower decrease button at all times ready to push if and when it starts going up. I am (nearly) 100% confident it is a mechanical problem with that button and not a computer issue as I have been dealing with it for a year and no module reset techniques have an impact. Since there are 3 methods to increase the blower motor on the vehicle and only one of the 3 is the culprit (the one I would naturally use the least), I am thinking about disabling the actual button instead of buying an expensive replacement module for a button I don't need or use. Unfortunately, the only way I can think of disabling the button is by physically destroying it. Easiest method would be to drill a hole straight through it or try to surgically cut that button right out of the dash with a dremel or something. Alternatively, a little less crude yet more work would be to remove the panel and destroy the solder connections behind the button. The only reason I haven't done this months ago is that I'm concerned destroying that button will either cause the button to permanently be in the activated position resulting in me never being able to lower the blower speed again or even worse, causing harm/errors to other climate control functions which all work just fine with zero issues. Does anyone have any advice or know how these buttons actually function internally to know the proper way to destroy them effectively?
