2007 XKR - i have this constant buzzing sound (almost sounds like the sound of a small, old school electronic bed side clock/radio) that is on 24/7, even with the car off. It can even be heard with the car running. It seems to be right behind the instrument cluster in the dash. If I don't drive my car for more than about 36 hours, it kills my battery. Have any of you experienced or heard of this or have a clue what it may be? Thanks in advance.

 

This sound is the aspirator fan for the climate control - but although you think it runs all the time, it does not. It starts to run the instant you pull the door handle, remains in operation all the time the engine is running and remains in operation for about 30 minutes after the engine is shut off. This is correct and normal. So naturally you think it runs all the time. It does not.
These fans sometimes become noisy if they get dirty; they are not particularly expensive and can be replaced quite easily if the noise bothers you.
But the bigger issue here is the fact that your battery is low. You need to address this separately because these cars require full voltage all the time; if they do not have it, random problems in any and all systems will result but the cause is always the battery. If your battery is more than 3 years old, if you use it primarily for low-speed short runs, if you do not use the car daily, your battery WILL run down. Solution: if the battery is more than 3 years old, replace it and more importantly, get a CTEK battery maintainer and use it whenever the car is not actually in use. The result will be ZERO problems. There are numerous threads on this.

 

Well done, Gregory! +1 on the CTEK. Just two more points:

(1) Remember to always lock your car even when it's parked in your garage. Locking shuts down all of the computers. Otherwise, convenience mode stays awake for a while (I think it's around 20 minutes) and that can cause a weak battery to run down further and not have enough power to start your engine, even though your courtesy lights may work.

(2) Keep your key fob at least 20 feet away from your car so it doesn't keep activating convenience mode and run down the battery.

 

tnx gents. yes....i'm all too familiar with the battery issues on these cars. it's a real PITA. i keep it now on a batt tender if not driving it over 24h. good thought too on the locking and the key fob. i often leave my key in my car and just close my garage. not anymore!

question....how can i get to this fan? is it easily accessible?

Our cars are now 10 years old, and almost every question you can think of has already been asked and answered. Learn to use the search function, and you won't need to reinvent the wheel.

 

still doesn't answer the question of where it is located and how best to get to it if it's not immediately accessible.

I'm exaspirated...

 

excellent, thank you stuart s.

A little more info if it helps. Jac

 

thanks!!

 

So you are recommending that people do a search and depend on 10 year old information?


Reinventing the wheel is exactly the benefit of this forum vs. a search tool. The search function has its place but so is the input of new information that is not yet searchable. Quite often somebody will post a new way of doing something that has not yet been put up on the internet [thus it is not searchable] and because somebody asked the question- that person then put a new solution [and now it is searchable]


Also new technology comes out all the time> new tires, new brakes, new batteries, etc and telling somebody to use the search tool won't yield this new information.
I personally encourage all questions and I do not suggest depending on the search tool only. Before the internet, everybody said 'use the Haynes manual'...please let's not go back to those days.


Keep the questions coming.

 

agreed and thank you. yes, i did try and search, but it did not yield what i ended up getting by creating my own post. hence the post. no question is really too dumb and needs to be shot down. if it annoys you....just ignore it. i've answered a ton of "annoying" questions on other car forums. if i can help a guy quickly....i just do. the time it takes to tell them to "use the search button you jack ***", i could have answer the question or provided a link to the answer.

 

Of course not. That's not what I said, but if that's what you understood I'm puzzled because I thought my advice was clear and unambiguous. I stated: "Our cars are now 10 years old, and almost every question you can think of has already been asked and answered. Learn to use the search function, and you won't need to reinvent the wheel. "

Are you saying that you can't depend on 10 year old information? I doubt it; it depends on whether it's still valid.

What I said was use the search function and see if your question has already been answered. If not, then ask it. This forum is full of questions that continue to be asked, even though the answers were posted years ago. An example is "One of my backup lights is out."


The search function is a valuable resource and is one of the best features of this forum.

I prefer to rely on myself and try to try to find the answers to my questions before asking others for help. That was a valuable lesson I learned many years ago from one of my teachers who said: "Give a hungry man a fish and he won't be hungry tonight. Teach him how to fish and he won't be hungry for the rest of his life."

 

Sorry Stuart, he'll still starve, if he needs it cleaned and cooked for him.

 

Honestly i hate the search function - or it comes up with nothing or with to much topics i am to lazy to search.

:P

 

Yes, that is exactly what you said. Telling somebody to use the search button is useless if he is posting a question. He clearly either searched already and did not find the answer or he does not want to bother to search and just wants an answer. If you know the answer then just give it to him, if not then ignore his question.

The last thing we need is yet another person telling everybody to use the search button.

 

I'm not going to get into a pissing match with you because I know what I said and what I meant. What you understood is your problem. What did you just accomplish? (A rhetorical question; no answer needed or expected. )

 

So, out of 6050 threads in this forum, 42 mention the "search function" and only 3 mention the "search button" (isn't 'search' a great thing?).
