timbo https://youtu.be/riC13zbjdgg I'm pretty sure your cabin temp sensor will be in the CCM module as detailed in this video. I don't think the link works but you should be able to cut and paste into YouTube search
Brownie copying link just gives me error message "404 file not found". Where is CCM module located? Thnx
timbo Just type "volvo ccm temp sensor" into YouTube there's a video detailing how to clean it. CCM is the climate control module
Brownie Thanks heapz for the info ,just You Tubed it. Totally different to previous info I had received.
