Replacement Heater Control Panel Not Functioning On All Controls

[pinheadplanet]

Hi

 

I just replaced my Heather Control Panel on my 2008 C5 exclusive witha unit from a breakers but the following do not work.

 

Front Screen Maximum button

Turn Off A/C

Any of the 3 vent direction buttons

Turn off Auto

 

Do these units need 'coding to the chassis' like the car stereo? Like an anti theft safety mechanism?

Many thanks

Did you get the correct part since there is a part no. change at RPO 12019  - up to this 6452H7 or 8 depending on colour and after this 6452R9 or 6452S0 depending on colour for the 2008 on C5 (X7). The Citroen service box procedures make no mention of any coding.

Oh wow sorry for not getting back to you Paul, only just seen this, I was expecting to get an email if/when someone replied but I didn't.

 

As far as I can tell it was the correct part (but how would I know?). The BEHR number on the stricker is the same.

 

As far as I'm aware it is the 6452H7 as that was the part number citroen told me that I needed. The ony difference I'm aware of is that the replacement unit came from an estate.

 

What is RPO 12019? and

 

Is there a visible difference in the 6452R9/S0 units or will they have different serial/part numbers on the stickers?

 

Cheers

I do not know what the difference is between the part numbers. The rpo is a code for the manufacturing date and can be found on the tyre pressure sticker on one of the door pillars, as well as in the Warranty and Maintenance book inside front cover.

 

Using 12019 equates to a production date of 5/10/2009 http://www.citroen-ds-id.com/gen/Gen_Organr.html  so for a 2008 car you should have the correct part number.

 

Did your original controller have any problems ? If the unit from the breakers is not faulty, then you could try a battery disconnection/reconnection or a bsi reset. In the C5 Technical Section there is a procedure for the disconnection in the pinned Common Problems topic which I use and a pinned bsi reset topic.

The unit has gone back now, crickey I hope it was faulty and this couldn't have just been remedied with a battery disconnection.
