Maintaining Jaguar S-Type R: Part Sixteen A (Climate control system diagnosis)

Hi All, First instalment of a multi-episode part sixteen featuring my Jaguar S-Type R and it's climate control system that now blows hot and cold air regardless. This video covers the diagnostic steps followed to troubleshoot where the issues lie. Below I've included some handy links that I read-up on before commencing any troubleshooting steps. I've also included the tools and part(s) used / referenced so far. As this is a long video, I have indexed so folk can jump to the relevant sections as required. Finally - big shout out to the folk on the Jaguarforum who have helped me a lot with this one. DCCV (Dual Climate Control Valve) and RCCM (Remote Climate Control Module) replacement video link below.
