Polo 9n3 heater issue
Hi Guys
Posted a while back about my wifes polo had 1,2 issues which where sorted out (thanks for the help ). But i dont know how to fix the heater issue she is having.
The dial that changes from cold to hot does not seem to do anything. Stays on cold the whether its turned to hot or not. I checked up on the interwebz and got this
Is this my problem and is it really THAT hard to fix?
If not what could it be??
TIA
Shaun

I could only find these:

"Ok, sounds like there's a problem inside the car with the way the heater directs the airflow. Twist the hot/cold knob, whilst looking under the dash behind the heater controls. Best view would be from the drivers footwell. You should see the cable moving, and this in turn will lift a flap (which you can't see, as it is buried in the whole heater casing). Check the end of the cable is attached and you can see it moving.
This sounds like its going to be tricky to diagnose, and if the heater box is faulty, then it's a pain to get to I think. If its the same as the mk3, it means the dash needs to come out. "
For a combi, but it may give you an idea...

"There is a bowden cable connected to the back of the temp selector. If you are lucky it has simply fallen out/unclipped itself.
ETKA is showing 7H2 819 837 C as the cable on illustration 820-05.
To service
- remove facia trim
- undo 4x bolts holding selector control
- access cables "

Re: Polo 9n3 heater issue
Marco if you turn the heater dial does it feel very smooth or can you feel the dial turning something on the other side. My wifes one feels as though it is moving freely without being attached to anything
Thanks for the links ill have looksee now

Re: Polo 9n3 heater issue
How do you remove the dash facia by the heater controls??? Does it just clip off?
Scared to break it when I pull.

Re: Polo 9n3 heater issue
Shaun, I may be wrong but had the same problem on my polo.... there is a wire with a little hook that clips onto the back of the switch unti.... mine had popped off and so when you turned the switch, it was not moving the wire to open the heat.... if that makes sense....
Hopefully it is something small like that?

Re: Polo 9n3 heater issue
If you turn the dial you feel a bit of resistence and will hear movement below as it changes the heat in the core.ShaunTdi wrote:Marco if you turn the heater dial does it feel very smooth or can you feel the dial turning something on the other side.

Re: Polo 9n3 heater issue
When I try my heater dial, it feels free / no resistance. But Hot / cold works just find.
Think the switch is attached to a motor? (Obviously by an electrical wire )

Re: Polo 9n3 heater issue
The only cable there is is for the vent flap position.
The heater is controlled through a motor.
Get on ya back in the passanger footwell look up next to the air box you will see a motor with two gears.
When you move the dials the motor will move.9 out of 10 times the top gear on the flap clips out.Clip the gear in and see.

Re: Polo 9n3 heater issue
Right so I have taken the front facia by the dials off and everything looks hundreds the dial does in fact have some resistance so like Morne (Thanks ) has said it is possibly the clip that is out.
Tried to look under the dash on the passenger side while turning the heat control dial but I see nothing moving. Dont really know where to look but I do not see or hear anything at all. Would it be quite noticable if you turn the dial Morne??

Re: Polo 9n3 heater issue
You will have to remove the glove box to get better access to the "airbox".ShaunTdi wrote:Right so I have taken the front facia by the dials off and everything looks hundreds the dial does in fact have some resistance so like Morne (Thanks ) has said it is possibly the clip that is out.

Three torx screws inside glove box and I think about 8 underneath. First you take out the lower cover (two screws) then the little shelve below the glove box (3 screws and you let it hang) and the the last three that hold the glove box.

Re: Polo 9n3 heater issue
There are no screws inside the glove box like you said. I have removed the tray below the cubby and about 5 screws that hold the cubby but the thing is not lose at all.

Re: Polo 9n3 heater issue
There are 3 screws inside the glove box, one long one by the latch in the middle and two to the side. It is close to edge at the top.ShaunTdi wrote:There are no screws inside the glove box like you said.
