Ive got a 05 cayenne S with 86,xxx kms on the odo....

anyways, everytime i get into the car and windows are fogged up,
I start up the engine, and it take atleast 5minutes for the defogger to blow.

It get really frustrating when im in a hurry because i cant see anything!!

Is it just me? or anyone else experiencing same issues?

Thanks in advance!!

 

In order to defog your windshield, it has to blow warm air, and when you cold-start your car, there is no way that it can blow warm air. So, we're all living with it, you're at least complaining about fog, here in Michigan, I sometimes wait 10 minutes just to de-freeze the windshield..

 

Wow, thats some crazy weather you got going on !!

I understand the car has to be warm in order to blow warm air, but even if already warmed up and i drove to say the the gas station to get a drink, i come out and my defogger wont turn on for 5minutes. its not that it wont blow air. it wont turn on evey time i restart i engine.

 

its normal ... i mean come on ... engine needs to warm up

 

I guess ill just live with it!!, just a question whether its warmed up or not wouldnt it still blow cold air?... reason being my M3 when i start it and turn on the windshield defogger it blows cold air untill the engine is fully warm. i was a abit concerned when the cayenne didnt at all.

Thanks for the response!!

 

is it not blowing at all? that's not normal, it has to blow at least cold air. have it checked then

 

yeah!! thats what i was saying.... i guess ill have to bring it in, my warrenty would cover the cost right? assuming something those need to be fixed

 

if you're still covered, yes it should be on Porsche, not you

 

Yeah i got until november or 120k, ill prob bring it in on monday

thanks for the response guys!!

 

if it started blowing after you started the car cold it would probably add another layer of ice to the inside of your window....
the thing needs to warm up!

 

Yes it needs to warm up, but it blows nothing!!! not even cold air

 

if ur car does not blow hot air even when the car has reached its full engine temp. then maybe its a problem with the blend doors. need to be replaced
