I have a 2016 CTT. I have had a problem with one of the rear A/C vents (console), not blowing, or blowing very slowly since I first bought it with 10K miles in 2017. I have taken it back to the dealership and they have fixed it twice. Today, it started blowing slowly and I am confident it will eventually quit blowing. The past two times, they have replaced the blower motor or a solenoid. I strongly complained the second time it happened and I was told they just replaced the faulty part. I am sure they will replace something this time as well, but i don't have faith it will be the end of my problem. Has Porsche stopped diagnosing problems and just replacing parts? Has anyone had this problem with their 4 zone A/C and/or the Porsche dealership?

Honestly, I love my CTT, and even though I have CPO through next year, but I am not a big fan of problems and tempted to trade it in.

 

Ask them why the blower motor keeps failing. They should be able to test it. On some BMWs there is a final stage resistor that causes similar issues. If they replace the parts and the issue is resolved then later returns either the new part is bad or something else is causing it to prematurely fail.

 

I have an appointment 8/3. Hopefully we will get some answers.
