2007 Citroën C5 climate control panel, CD unit and side mirrors not working.

Post by zackc5 »

Hi to everyone. First time on here. Hope someone can help me.
Last week I removed the stereo unit and aircon climate control panel to replace a broken ashtray and when I fitted it back together the climate control is stuck in 18°, the fan stays on and can't be turned off, the CD changer doesn't work and side electric mirrors don't go up and down or sideways.
I've tried BSI reset but to no avail. I've used lexia and it is showing permanent CAN undefined faults with radio and no dialogue with A/C .
Can anyone PLEASE PLEASE help?
Thank you.

Hi, unfortunately is seems like you have probably disturbed some of the CAN wiring at the back of the fascia whilst doing the repairs. In this case, it's going to be a matter of retracing your steps and carefully checking each wiring connector and surrounding connections to see if you have knocked one loose.

As the CAN (or likely VAN) wiring in this case has been affected, it is impacting on the other non-critical systems like the wing mirrors and the climate.

It won't be a BSI reset that will help as the BSI is tucked away behind the glovebox, so will unlikely have been touched or disturbed. So check the wiring bundles and make sure that none of these are being pressured that could of caused a break or a loose plug connection.
