Hello fellow Volvo enthusiasts, this is my first post and hopefully I am following the rules correctly! I have looked through older posts but nothing stands out as a potential answer to my issue.

I am unable to control the temperature in my XC70. The driver side will only blow hot air and the passenger side only cold. The car has been to Volvo (and a fair few local garages before that) who haven't been able to reset the error codes and tell me I need a new Climate Control Module. I have searched ebay, amazon and most breakers yards who sell online for a replacement but the part number 30782904 (and importantly the bottom buttons) differ from anything available. In addition there will be reprogramming costs and I doubt Volvo will do that for a second hand part. I have found a place in the States who offer to repair my old CCM but they want a ridiculous amount in shipping to get the old part there and back. Incidentally on their website it is suggested this is a known common fault with P3 Volvo's

I am running out of options and before I re-mortgage my house to pay Volvo to replace the CCM I wondered if anyone has any pearls of wisdom? Sadly I am not under warranty.
I am living in Spain but hoping someone out there knows of other companies who repair or specialise in Volvo parts? (in the UK preferably for me)

Thanks in anticipation PJ
