Hey I'm looking for help with my climate control module. when I bought the car the clock was cycling through minutes like they were seconds and had thought that maybe the buttons that change the time were stuck pushed down. I never found a way to fix it and now the hours are doing the same thing, just constantly changing. However when this problem started the controls stopped working. I can press mode and change the direction of where the airflow will come out of, but I cant actually turn my air con on. I opened it up and everything visually looks ok on the board (nothing burnt out) and I don't know of any other ways to fix it. Id preferably not have to buy a new one but if there is no fix I guess ill have to. 

Any advice is welcome

It is a reasonable guess that there is a problem with one or more buttons. If one is stuck on or shorted in some way, it could prevent the other buttons from being registered. I'd be taking the buttons apart and looking for dirt/scorching/etc in the contact pads.

Bump

I’m experiencing the same issue in my GTT. I don’t think any of the buttons are stuck and when this problem first started I was driving during one of the heaviest storms I’ve been in and when I turned on my A/C to defog the windows it happened (first controls and clock not working, then after restarting the car only the clock). 
I suspect some water got into something it shouldn’t have /fried something ?

The rest of the A/C controls are fine and the clock counting up will go away for a few days/weeks then randomly return. Any help as to how to attempt a fix would be greatly appreciated 🙏🏻🙏🏻

Sounds like water in somewhere [genius ...I know].......probably go away in the summer, just park it in the hot sun for a few hours.

Otherwise, if you need to do it now, its a strip and dewater/clean.

Bit of a late reply, but I can almost gaurantee that it's none of the above - I and it seems at least 2 others have the exact same issue - I pulled apart my AC unit, and found that it has some form of charcoal substance surrounding the 3 buttons (For whatever reason Nissan decided to put this in) - and the only explanation I have is that it's causing the buttons to corrode/ short or something. I unsoldered the 3 buttons, which caused the clock to stop counting up, and the AC unit to work - super easy and free fix, saving upwards of $400- 600 AUD. I made a little guide, I'll just attach the screenshots of the guide here:

Yeah pretty simple fix if you've got a soldering iron. I personally haven't soldered new buttons on yet - but it's as simple as finding a 2 prong button from any electrical store - for Australia I'll be using just Jaycar.

      New fix for low tyre pressure from bmw

      By MBS206 · Posted

      Yep, pretty much what you said is a good summary. The aftermarket thing just attached to the rim, then has two lines out to valve stems, one to inner wheel, one to outer wheel. Some of the systems even start to air up as you head towards highway speed. IE, you're in the logging tracks, then as speeds increase it knows you're on tarmac and airs up so the driver doesn't even have to remember. I bet the ones that need driver intervention to air up end up seeing a lot more tyre wear from "forest pressures" in use on the highway!

      Anyone know this frontpipe?

      By sunsetR33 · Posted

      Yes, but you need to do these type certifications for tuning parts. That is the absurd part here. Meaning tuning parts are very costly (generally speaking) as well as the technical test documentation for say a turbo swap with more power. It just makes modifying everything crazy expensive and complicated. That bracket has been lost in translation many years ago I assume, it was not there.

      Hahaha, yeah.... not what you'd call a tamper-proof design.... but yes, with the truck setup, the lines are always connected, but typically they sit just inside the plane of the rear metal mudguards, so if you clear the guards you clear the lines as well. Not rogue 4WD tracks with tree branches and bushes everywhere, ready to hook-up an air hose. You can do it externally like a mod, but dedicated setups air-pressurize the undriven hubs, and on driven axles you can do the same thing, or pressurize the axles (lots of designs out there for this idea)... https://www.trtaustralia.com.au/traction-air-cti-system/  for example.... ..the trouble I've got here... wrt the bimmer ad... is the last bit...they don't want to show it spinning, do they.... give all the illusion that things are moving...but no...and what the hell tyre profile is that?...25??? ...far kernel, rims would be dead inside 10klms on most roads around here.... 😃

      You're just describing how type certification works. Personally I would be shocked to discover that catalytic converter is not in the stock mounting position. Is there a bracket on the transfer case holding the catalytic converter and front pipe together? If so, it should be in stock position.

      You talking about the ones in the photo above? I guess that could make sense. Fixed (but flexible) line from the point up above down to the hubcap thingo, with a rotating air seal thingo. Then fixed (but also still likely flexible) line from the "other side" of the transfer in the hub cap thingo up to the valve stem on the rim. A horrible cludge, but something that could be done. I'd bet on the Unimog version being fed through from the back, as part of the axle assembly, without the need for the vulnerable lines out to the sides. It's amazing what you can do when you have an idea that is not quite impossible. Nearly impossible, but not quite.
