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.
Why is the solenoid on my Jaguar heater not working?
It is an active low circuit, so when the DCCV sees Ground at either the LH and/or RH pin, the respective solenoid within the DCCV activates. Case 1: Temperature setting “Lo” = CCM output ON (grounded) = solenoid ENERGZIED = solenoid valve CLOSED = coolant flow to heater core impeded = heater core NOT HOT when A/C is ON.

Where are the temperature sensors on a Jaguar 03-08?
4. Check the Evaporator Discharge Temperature sensor (s) located under the dash. On the 03-08 S-Type, there is one (1) sensor at the passenger side, and two (2) sensors at the the driver side, all attached to the Evaporator housing under the dash, just above the transmission tunnel. Measure the resistance of each sensor.
Is there over current fault protection on Jaguar S-types?
There is no over-current fault-protection circuitry that protects it against damage due to faulty Heater Valve. This applies to S-Types from (late 2002) through 2008.

What kind of compressor does a Jaguar air conditioner use?
AIR CONDITIONER COMPRESSOR: Up through 1992, the Jaguar A/C compressor was labelled “Harrison” but was in fact the standard GM item referred to as an A-6 — and therefore comparatively cheap to replace. In fact, it is generally recommended to simply replace the compressor rather than attempt even the simplest repairs.
What’s the difference between thermal and pressure switch on Jaguars?
According to Stefan Schulz, Jaguars began being fitted with this type from the factory in the mid-80’s. Note that the thermal type switch is normally open and connects to ground in the event of trouble, while the pressure type is normally connected to ground and opens in the event of trouble.
Where is the compressor protection circuit on a 1983 XJ-S?
COMPRESSOR PROTECTION CIRCUIT — A-6: Just below the inlet and outlet connections on the A-6 compressor is a sensor held in place with a C-clip, with a wire connected to it. On the 1983 XJ-S, this is a thermally-operated switch that shorts to ground in the event that there is trouble with the freon system.
How many ohms are in the climate control on a Jaguar?
Did some research and found that normal operation is that each solenoid should draw less than 1 Amp. Tested DCCV solenoids for resistance. Passenger side 12 ohms (a bit low), drivers side 9 ohms (too low). Bought new valve on net for £79, arrived next day.
The 1999 – (early 2002) modules, though still susceptible to damage, have a more robust design that reduces the chance of said damage. For 2003-2008 models, there are three (3) versions of the module.

Where is the a / C pressure sensor on a Jaguar?
A/C pressure sensor/switch: 2. Check the fuse for the Heater Valve. It is Fuse 32 (10 amps) in the Front Power Distribution Fuse Box, located in the engine compartment. This fuse is hot +12 volts at all times, and also feeds the Auxiliary Coolant Pump Relay (4.0L models) and A/C Clutch Relay.
When did the Jaguar S-type air conditioner fail?
Common failure for Jaguar S-Type models built between 1998 and 2008 is the climate control module. Once this becomes faulty the heater will constantly blow hot air regardless of the temperature that you set it to. The other main fault that this module can suffer from is a complete failure to operate.
Why is my air con not working in my Jaguar?
Pull the 5 screws holding the top radiator mounting bracket and take a look between the condenser and radiator. They have a way of accumulating a lot of trash that restricts the air flow. The coolant temperature might stay in the normal range, but it greatly impacts the A/C efficiency.

Why is my car a / C blowing hot air out of the vent?
Your car’s A/C system is one that operates a little differently than you might think. Instead of actually creating cool air, it instead removes the heat and moisture from the air inside of your car, leaving you with cooler feeling air.
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.

The car was such a beauty. i later found out that beauty isn’t everything when within the first year of owning this vehicle I’ve had to replace the starter, water pump and transmission. this car has cost me 7k, almost more than it’s worth. i guess it’s a lesson learned. I’m writing this review to help anyone anyway i can. Was this review helpful?
Why is the fan running in my Jaguar?
Lift off the engine cover & touch one of the charge coolers, it should be noticeably cooler than the alloy intake tube that runs between the charge coolers, if it’s the same temp or warmer then i’d be looking at the intercooler coolant circuit and the electric pump. But the thermostat should also be on the list.
What causes the climate control on a Jaguar to reset?
Not sure if this is the answer but the manual suggests that disconnecting the battery will cause the system to reset to an ‘average automatic setting’ (412-04) when power is restored. I have the opposite problem, hardly any warm air to the feet.
