Climate Controls

[marcr]

I'm having trouble working out what i can expect from the rear heater. I've got front and rear climate controls on the dash - no other controls towards rear etc. The hand book's no help.

 

I can use the front section ok but can't seem to figure the rear one out. Should it work the same as the front? Is it working off the same system? For example - when i got in last night it said 9^oc. put both climate temps to 25 and turn the fan speed up. Front one works fine but the rear one returns to minimum speed. I turned it back up to full, can hear it blowing full speed but then returns to minimum within 10 seconds. The symbols on the dash show me it's slowing down i just don't know why it won't stay on. Is it the external temp?

 

I've read up about aux/booster heaters and had a look under the car. Can see two pipes running from engine area to rear wheel arch where the disapper up behind and into car. The rear blower unit is over this wheel arch internally.There is NO exhaust pipe sticking out anywhere or any unit with a glow plug. Am i missing something?

 

Could anyone tell me how it works? A picture of a explanation in a decent handbook, a link to somewhere, anything.

 

Thanks

Hi, a blower under the dash makes an annoying noise as if the bearing is gone, can anyone tell me how to get to it, service or replace it? Any help is much appreciated.

you dont have one its a TDI thing

If the rear fan speed keeps returning to low then it sounds like the button that turns the fan speed down is sticking. Mine does this occasionaly and i've found that pushing the corner of the button ususaly unsticks it.

 

The pipes running to the rear feed into the rear aux heater which works the rear a/c. There is a diagram of this in TIS but my CD is broke so can't post it to show you.

Haha. :D :D :o Such a simple thing and i didn't even think to check it!! The button was stuck. It was starting to bug me too. Thanks for your advice Joey - goes to show the beauty of this forum.

 

Many thanks.

I took a coupleof months of use before mine came unstuck for good!!! Put up with it for now and it will fix itself (unlike all the other probs galaxy's have)
