Hello all,


Last weekend I was out, it was chilly outside so on my way back 2am I crank the heater, to my surprise the thing is blowing cold air lol

after a few miles I stopped at a gas station, turned the car off and on, I crank the heater again and now the thing works..

I had the car at the dealer for some warranty issues on my seats this week, so I ask the S.A to check the heating, he is like ok.. takes notes ..

after 4 days because they didn't have parts for my other issue, dealer returns my car so I called the S.A. about the heating and he tells me everything is working fine.. btw no paperwork.. ( I think they didn't even bother to check the heater)

today I go out for a drive and the heating is not working again blowing freaking cold air I put 85+ and a/c off and 10 miles of driving and nothing

so I had to go inside some store for about an hour, after that same thing, on my way back..cabin temperature like summer days nice cold air..

tonight I'll have to jump in the Cayenne..

anyways I was reading the thread about the solenoid being defective ... anyone already changed a faulty one? planning on buying the part and just doing it my self, maybe that can take care of the problem

I think I'll do it my self, since I'm not getting a lot of help from dealer

 

I just went through this. Sounds like a bad Change Over Valve.

Had similar a problem. Valve was replaced two weeks ago by dealer. Heater was blowing cold air when I arrived there for other service, clearly not working. New wiring harness was needed with the new valve. Was on back-order. Drove a loaner for several days until it arrived.

So far so good with the new valve.

 

I dropped my 2013 C4S off at dealer with same heater issue, told them I read it was a solenoid problem. A week later (yes it took them a week) they call me to tell me not fixed yet but they think it might be the solenoid. Pick it up in another 3 days (1.5 weeks total). Three hours later, blowing cold air. I don't think Porsche has very high requirements for their technicians. As a side note, at one point they told me they had to take my car out of the service bay to work on someone else's car? I did not purchase from this dealer, I guess when a car purchased at dealer comes in they yank whatever is being worked on if it was not purchased at dealer. I was shocked SA told me this, but like I said, not the brightest over there...

 

wow
that was a long wait

 

Known problem in 2013 models. There's some valve that sticks. I thought I had it but got heat now. What I do is set temp at 80' then when it starts heating I lower to what I want.

 

I had the same issue, change over valve was the fault, dealer knew what it probably was before booking it in, confirmed by mid day, replaced back and working next day. My dealer is very good, this shouldn't take long to resolve, but I would highly recommend my dealer in the UK.

 

Just got my oil changed and my heater fixed... Same thing happened last year... Got it fixed the same day.... Go NYC ...

 

Do you know what the problem was?

 

Just completed my Porsche service survey regarding my last COV replacement which affected my heater. My car was fixed in less than a day from my showing up at the dealer without an appointment, so no complaints with the service whatsoever.

I lambasted Porsche in the section about how I feel about the car and their failure to recall known defective parts. Let's see if I even get a callback from them. Anyone want to bet? I give it 50-1 odds that there is no callback response.

 

I complaint last survey never received a call, I was there last week and mentioned the heating problem, no paper work they told me everything was fine two days later no heating, this morning I think heating was working, not sure, I turned the car just to check if I was getting warm air, I'll check again tonight

 

Bought my 2014 Carrera 991 last September. 2,425 miles on the odometer with absolutely no issues of any kind. Could not be happier with my 911.

 

Brought my car in 2 days ago because the heat wasn't working. I have a 2014 C2S with about 5500 miles on it and they said they have had several 991s come in for this. It was fixed in 45 mins.

 

Do you have the work order ? Was the bad solenoid?

 

They didn't give me anything when it was all done so I can't answer that unfortunately.
