The easy answer is that your DCCV is not fully closing on at least one side. This could be due to corrosion, debris, or mechanical failure of the valve, or a failure in the climate control board or wiring between the two.
However, you should execute Karl's excellent Climate control diagnostic in a systematic manner to be sure. I think it is still on the front page here, somewhere. If not it is certainly in the top 5 pages of threads, if not already in the stickies. Here you go, found it for ya: https://www.jaguarforums.com/forum/s...ol-how-185002/
None of the above apply if you don't have an S-Type (X200/202) and no one can tell from your post what you have. Please add a signature containing the Model year/engine/gearbox of your car so people can formulate more accurate and useful responses.
