HVAC control swap question LCD or LED out

[ivangene]

So on my 99' C2 the heater control has a couple sections of one digit number out when its at 80 I have a reversed "6" for the 8 and at 68 I have sort of a small "0" then the regular "8" so its just a couple on the first digit. all the 70's look great (gawd I hate saying that for some reason LOL)

I picked up a used unit that is correct for my year 996 653 101 03 but before I just plug it in, I saw I might have to configure it? If it doesn't work, can I just plug my old one back in or will I also have to configure it since it was removed?

I am not 100% sure the new (used) one works as there is a slight mark on the display...

Any chance of making one work from using parts of the new to fix my old one?

Thanks for your thoughts

No programming required, just plugs in. Very easy to swap parts between the two, if required. I used the LCD replacement kit on ebay for $55, took all of 30 mins to do, a swap out of a different unit is even less. There is a whole thread on it in the 996 DIY section.

I wanted to swap mine too as it had the same issue with the LCD screen.

I have a unit with the ending number 09 and I got a used part ending 03. I switched them over and the Dash died when I switched on. I think that's just a fuse. I also noticed that the new unit read in degrees F not C. I took the blown fuse and the deg F to mean it might be the wrong part.

I have also learned that the 09 part is just a newer version. In that case can I switch the degrees F to C some how? Am I likely to keep blowing fuses?

I sourced the part from the US but will that cause it to be different?

Any help appreciated.

An -03 will only work in a MY2001 car.

What is the model is your car (per the build date on the drivers door)?

Will have to check the build date, but its registered 2002 and is a turbo. Likely to be built that year too, I guess. So is it likely that it will not work with the 03 unit?

Thanks in advance.

Thanks Loren. That's got to be it then.

The part is on ebay and there is a big box of fuses coming the other way.
