Read evidence and context

Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Additionally, when I run POR, I see a warning for five errors, but when I try to display they disappear and POR reports no issues with the AC module.

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.

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

POST 1Original post

I have an issue with my climate control. A video link below shows the problem. I ran a CARSOFT POR 3 auto diagnostic, cleared the codes, and then the climate control started acting strangely. I'm not sure if this happened right after the diagnostic or after clearing the codes. In the video, you can see that all the buttons work except: AUTO: The fan goes full blast when pressed. Temp -+ : Changes bits of the numbers on the display but does not affect the temperature. It feels like it's stuck in diagnostic mode. Additionally, when I run POR, I see a warning for five errors, but when I try to display they disappear and POR reports no issues with the AC module.

POST 2Original post

Not familiar with that area / module but what I would do: 1. disconnect battery / fuse? 2. since you have the unit out, may be try to "clean" the "zebra" connector between the main board and the display? I would imagine the connection method is the same as CDR24 https://www.planet-9.com/threads/cdr24-display-fixed-and-lessons-learned.254723/?post_id=2219428#post-2219428

POST 3Original post

1. If the unit is out - nothing will be gained disconnecting the battery /fuse.. there is no power to the unit 2. Worth trying, but the coincidence of the display not being distorted or showing missing pixels - but showing what it is - which is the wrong items displayed after a diagnostics read was run on the car makes me think the display memory has somehow been corrupted. Luckily - if another "auto" unit from the same era can be sourced it probably can be swapped right over. I would be interested in seeing what another diagnostics tool might make of the 5 errors being reported - something like a Foxwell .. or Durametric. BTW - OP - Welcome to Planet-9, the Friendly Forum for Confused Porsche Owners! It's sort of traditional here to introduce yourself over in the new member area, and post a few pics of your car. Good place to do a bit of reading on how to make technical request posts (your's is excellent BTW..) and some other forum specific stuff. You can find all that at: https://www.planet-9.com/forums/new_members/ Welcome once again! BTW - I may decide to move this thread over to the Diagnostics forum we have - but that can wait until we see if any useful input arrives in the thread here..

POST 4Original post

I did the same thing and am having the same issue now. Anyone figure out a solution?

POST 5Original post

I went back and forth on this issue with both iCarsoft support and my local Porsche dealership. Neither were able to fix the existing unit. Porsche wanted >$1600 to replace the unit. I ended up buying a used one on ebay for a couple hundred. Swapping the unit out was the easiest repair I've done on this car. Took less than 20mins.
