Climate Control Unit - Part Number Confusion

[dyerhaus]

Hello! I'm experiencing some confusion with part numbers for the Climate Control Unit in a 996/986. Hoping someone here can help clarify things for me.

 

I’m looking to replace the Climate Control Unit in my 996 (2001). Looking through eBay I found one that not only works, but looks brand new. It’s part number is: 996-653-101-10

 

I pulled the one out of my car, and its part number is: 996-653-101-03

 

I pulled the one out of my Boxster 986 (1997) and its part number is: 996-653-101-00

 

In PET, there’s two other potential part numbers: 996-653-101-08 and 996-653-101-09 (and several others I've found on the internet, such as 01, 05, and 07)

 

The problem is that all of these look the same. They all have the same connectors on the back, controls on the front, and the display is the same on all of them. The only difference I can find is the color of the plastic in the back that no one will ever see because it’s mounted in the dash.

 

Can these be used interchangeably? If I bought 996-653-101-10 and replaced my current unit (996-653-101-03) in my 996, would it work?

According to Porsche (for your 1997 Boxster) only these part numbers will work:

 

996-653-101-03 EFR

996-653-101-CX EFR

I'm replacing the unit in my 996, but PET says the same thing for that as well. The problem is finding that exact part number in the condition I want (new is way too expensive). I've found other part numbers in the condition I want, and they all look the same. I'm willing to bet they all work too, I'd just like to find a definitive answer. I work in the computer business, and every computer manufacturer (just like car manufacturers) make certain parts for certain products, but that doesn't mean other parts won't work - the manufacturer just doesn't "support" them. For example, I have the Porsche Classic Radio Navigation system in my 996, but it's only supported by Porsche in Air-Cooled models.

The display is an issue in my Boxster (986), so I'll be using that fix for that. The 996, however, has a minor display issue but really has functionality issues. One of the buttons doesn't work and it can't seem to work in "automatic" mode to save its life.

You might try salvage yards for the 996 then.
