Why is my DCCV not working on my Jaguar?
The information provided was that the DCCV in a relaxed mode (no power/control) is a wide open heat mode. With the plug removed I had the same results, no heat to the driver’s side. At this point I replaced the DCCV. I was a little apprehensive that the DCCV was the cause until I took it apart and found out how it worked.
What’s the temperature of the heater on a Jaguar?
What I found is that the heat in the car was about 20° cooler on the driver’s side with the control panel set to 85°. I went to the DCCV and checked the temperature on the three heater tubes going back to the firewall.
What kind of DCCV does a Jaguar S-type have?
There are two types of DCCV, a 5-PIPE version and a 3-PIPE version. The 5-pipe DCCV is fitted to all Diesel engine models, and Petrol models 1999-2002. For an example of this item see the following link S-Type 5-Pipe DCCV. The 3-pipe DCCV is fitted to all Petrol models 2003-2007. For an example of this item see the following link S-Type 3-Pipe DCCV
Why does my jaguar’s type have hot air on both sides?
Sometimes just one valve will stick, causing hot air on just one side of the cabin, and sometimes both valves can stick causing hot air on both sides of the cabin. It is VERY important to fix this issue as soon as possible, as further damage can be caused to the heating system if the DCCV is not repaired or changed.

What causes a Jaguar climate control to fail?
When the Heater Valve becomes faulty, it begins to draw too much current, which causes the Climate Control Module to become damaged (i.e. failure due to over-current condition). 4. Harness/wiring problems between the Heater Valve and Climate Control Module. 5. Failure at one or more air mixing/blending flaps. 6. Or a combination of the above cases.
