Jaguar XJ6 air conditioning control system diagnostics

This video is not intended to be a complete tutorial but rather my sharing what I’ve learned in talking to experts, studying the relevant wiring diagrams and performing tests on my car. It covers vintage Jaguars that use the Delanair MKII System used in 1974-1987 Jaguar XJ6, XJ12, and XJS Series 2 & 3 luxury vehicles

Below are the links I mentioned in the video.
