Suggestion

If you check the Porsche Service Information book (oops, there, I did it again), you'll find that there's no clutch on the 981 AC compressor -- so there's really no "cycling." The compressor uses a variable-pitch swash plate to adjust its output, but the compressor shaft is always turning when the engine is running -- whether the AC is on or not.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

7 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1Original post

I just bought a Boxster (2011) that had 90% of what I was looking for. One of the items that I was wondering if I could swap out is the HVAC controls. I have the one with fan and temperature control I would like to upgrade it to the one with selectable temperature I was looking at Porsche OEM Parts - Genuine Factory Parts Accessories - Wholesale and found one listed as DASH CONTROL UNIT Boxster; Auto Control; w/Seat Heater; w/Ventilated Seats Does anyone know if I can put out the existing unit and push in the upgraded one? Basically, is wiring harness and the sensors the same for both units, and the intelligence for the 'auto control' (selecting 72F) built into the module that I am changing, or is there more to it, such as programing, and the addition of temperature sensors? (I know the seat venting will not work as I assume the seats do not all ship with fans). Thank you in advance.

POST 2Original post

Dropped by the Tyson Corner (VA) Porsche dealer's part department, and they claim it can not be done I am not confident with the answer because it was not "you can not because ....." just no. I will keep looking.

POST 3Original post

Did you search here? Seems like this question comes-up about once/year. And I think (not sure) that someone bought one off ebay and got it to work. Or that could just be the booze....:beer:

POST 4Original post

I did a few searches using different terms and find the issue with paint coming off of the controls but nothing on switching them. I found a shop guide that seems to indicate that the plugs at the back are the same on both units. The issue as I see it is the temperature probe in the unit, or is it elsewhere, and if elsewhere, is it installed by default.

POST 5Original post

Try "climate". I took a quick look and saw lots of "No Way"'s

POST 6Original post

Thank you for the tip to change the search " According to the Porsche Service Information book (PNA 981 BOX 13), there is a significant difference in the behind-the-dash hardware when dual zone climate control is installed." ​ this might be just dual as " If you check the Porsche Service Information book (oops, there, I did it again), you'll find that there's no clutch on the 981 AC compressor -- so there's really no "cycling." The compressor uses a variable-pitch swash plate to adjust its output, but the compressor shaft is always turning when the engine is running -- whether the AC is on or not. Variable AC loads are addressed by changing the angle of the swash plate." ​ and "...... He said that they may have a solution that they want to try out; it consists of adding a sensor and reprogramming the system to implement single-zone ACC. Apparently, it could be done on the 987." ​ Then the final nail in the coffin - http://www.planet-9.com/987-cayman-boxster-service-tech/4653-climate-control-swap.html " Well, the dealer ordered the automatic unit for me and they installed it and tried to get it to work for about 2 hours. 3 hardware codes came up that they couldn't resolve. After a phonecall to Porsche (why they didn't do this first?), they determined that it cannot be done without changing the wiring harness and other parts of the climate control system. " ​ so that is that.
