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.
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.
How to diagnose a heater leak in a Jaguar?
1. Unbolt the Coolant/Water Expansion Tank, set it aside so it doesn’t block access to the Heater Valve. 2. Loosen the bolt that secures the Heater Valve to the car. 3. Rotate the Heater Valve to get access to its connector. Procedure A (This one is messy. We recommend that you do Procedure B instead.):
Do you need a technician to work on a Jaguar?
If you do not feel comfortable working with the vehicle, it is highly-recommended that you use a well-qualified professional mechanic/technician to perform any work on the vehicle. JaguarClimateControl.com is not responsible for any damage or problems caused by use or misuse of this information.

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.
Why is my jaguar’s type not cold?
2005 Jaguar S Type the air conditioning is not cold. The heater control valve is corroded and failing to close, so the heat is on all the time. The Climate Control Module may have been damaged when the heater control valve failed. Yet to be seen.
Is the air conditioning on in my 2005 Jaguar?
This is one in a series of videos produced by European AutoWerks, your Jaguar Service and Repair Specialists in the Temecula and Murrieta area. 2005 Jaguar S Type the air conditioning is not cold. The heater control valve is corroded and failing to close, so the heat is on all the time.
What are the fuses on a Jaguar X-type?
Fuse box diagram (fuse layout), location, and assignment of fuses and relays Jaguar X-Type (2004, 2005, 2006, 2007, 2008, 2009). A fuse is an element for protecting the electrical system. A fuse will trip (i.e. it will blow) in the event of a failure or improper interventions in the electrical system.
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.

Where is the climate control module in a Jaguar?
For 2003-2008 models, there are three (3) versions of the module. In cars without navigation, the CCM is part of the Climate Control Assembly. Cars equipped with navigation use a Remote Climate Control Module (RCCM). The RCCM is hidden behind the glovebox.

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 kind of heater does a 2004 Jaguar XJ8 have?
I realised once winter turned up this year (Southern Hemisphere) that the heater on my 2004 XJ8 was pretty useless compared to my old X308. Using a temperature probe I discovered that the air coming out of the passenger side vents was 10 degrees warmer than the drivers side.
Why is my Jaguar S-type drawing too much current?
Both of its solenoids were drawing too much current (one of which was tested at over 6 amps, an 850% over-current condition!): 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.
How do you hot air a jaguar’s type?
With the valve, open re-fill the system until water starts to come back to the tank via the pipe off the back of the bleed. Once that’s done, start the car and run it with the heater on 29 degrees for 5 mins, topping up the tank as necessary. Once the water level is constant, close the valve and put the lid back on.
