Buzzing noise

I noticed today when I pulled up at work a buzzing noise I pinpointed that it was coming from the climate control area it was buzzing still when i got off of work 8 hrs later. What could be wrong?

It's the sampling fan in the IHKA panel. You think it was still running, because, as soon as you enter the car, it starts up.

The fan is probably choked with debris. You can remove the so-called cup holders and push the IHKA panel out. You can then clean the fan.

Thanks edjack !!!

I know this is an old thread, but I have a buzzing sound when I turn my key and I was searching for possible causes and I came across this thread and when I read that about the cup holders I blew Coke all over my monitor. Too Funny.

Thanks for the laugh first thing in the morning!
