Interior heating problem!?!

[gjameson]

I just joined the forum as i bought a 2003 Cayenne S for a very reasonable price.

Its been going well in the last few months until i cranked up the heat today.....

the driver side was warm and adjusting temperature changes, but the passenger side,

was blowing very cold air, no change with dial. I just can't believe half the car heats up

and the other side blows freezing air. :cursing:

Has anyone seen this before? Any help would be appreciated.

Thanks..... G

Its a UK model, steering on the right.

Either the AC controller is gone or the servo motors that side are gone. Hope you have a warranty

Thanks for the reply mudman. How much are you talking about for a controller?

I was just reading someone in the USA got one for $200 and replaced it themselves.

Is there a way of figuring it out if it really is the controller?

Thanks again

Not really, a PIWIS should be able to see it if you have a friendly dealer. if you can get one for 200, it might be worth a try

A new controller may be the ticket to fix your issue. But, you might want to check the servos first. Take the center part of the dash apart, plug in your controller and cycle through heat and ac. You should be able to see the flaps move. If one doesn't move, swap the plug with a different one to see if you have a faulty servo.

I bought my controller from sunset porsche. they had the best deal on the net I could find. I have to use mail order because the nearest porsche dealer is about 4 hours away from me.

That sounds awesome Josh! Thanks for your reply.

Porsche in the UK have advised me that the AC Control Unit in the dash

will cost me 218GBP or in $440. Its not a great price, but if I definitely know that

its the problem I don't mind paying that. I will look for description on taking apart the dash and

trying the servos out. I really appreciate the reply.

I took out the controller, but had no idea where to look for the servo that moves?

Any help of exactly where it is and how i would get to it! Thanks

Ok, I seem to have fixed my heating problem.

Joshmoney was right! I layed upside down in the passenger

foot well, underneath the glove box is a plastic protective cover which

is held in by 1 torx screw, if you remove that screw, the whole plate needs

a pull down to unclip, you then have a view of all the servo motors that

control the AC. They are blue in colour. As I raised and lowered the heat I

could see one having difficulty opening....it just rocked back and forth. I placed

my hand in and helped it open.....and VOILA! Heat on the left side.

Now after fiddling with it for a while it operates correctly on its own, no idea

but the AC control is great.....If anyone ever needs any clarification just msg me...

I will try and post some pics of the servo motors too.

Thanks to everyone that replied to my initial post!
