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.):

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.

How is quality control on a Jaguar XJL?

Press “set” and the hands start spinning to the correct time. Note how the grain in the burled elm wood trim is book matched left to right. Quality control can be meaningless when it comes to prepped press fleet cars, but with that caveat, there were few noticeable flaws in the review car.

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 does the blower speed control work on a Jaguar?

Blower speed control: In manual mode, rotate to select the required fan speed. Press to switch the Climate control system off. Press to turn maximum defrost program for the windscreen on/off. Heated front screen: Press to turn on/off.

Where is the hot water heater on a Jaguar?

Replacement is very difficult! Situated in the engine bay, close to the bulkhead (firewall) with two coolant pipes and a small vacuum pipe, this shuts off hot water to the heater matrix when max cold is demanded. It can become stuck open or shut but is fairly easily replaced.

How does the heated front screen on a Jaguar work?

Heated front screen: Press to turn on/off. The heated windscreen will deactivate after a predetermined length of time. Heated rear screen: Press to turn on/off. The heated rear screen will deactivate after a predetermined length of time. Do not scrape or use abrasive materials to clean the inside of the screen.

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.

Why is my Jaguar climate control valve not working?

If this condition is not attended to the result could be that the valve solenoids can draw excessive current and damage the Air Conditioning Climate Control Module (CCM) circuit board. Earlier models apparently were more tolerant to the higher currents and less likely to be damaged. http://www.jagtv.co.uk/videos/jaguar-… Loading…

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.

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. The 1999 – (early 2002) modules, though still susceptible to damage, have a more robust design that reduces the chance of said damage.

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 does the hot air tank work on a Jaguar?

To open it, turn it a 1/4 turn clockwise. This allows air / water to run down a pipe at the back of it, back to the expansion tank. 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.

How do you turn on a Jaguar heater?

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.

How many versions of the Jaguar control module are there?

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.

How does a heater control valve work in a car?

It uses heated engine coolant to provide heat to the passenger compartment. A heater control valve controls the amount of coolant flowing through the heater core. It’s not used in all heater systems, as some manufacturers allow coolant to flow through the heater core any time the engine’s running.

Can a faulty heater control valve be repaired?

To repair a faulty switch, you sometimes have to replace the heater control. Depending on the amount of vacuum, the vacuum motor will close off the flow of engine coolant fully or partially. However, even if the heater control supplies vacuum the mechanical portion of the valve can fail, preventing the heater control valve from closing.

How does the air conditioning work in a Jaguar?

The evaporator core absorbs heat from the inside of the car, sort of like a radiator in reverse. It does this when the blower fans blow warm air over the evaporator core. Once the system is in operation, the heat absorbed by the evaporator core is transferred to the refrigerant at the moment of evaporation.

What does the condensor do on a Jaguar?

CONDENSOR – This is the thin radiator in front of your engine’s radiator. At this point, the refrigerant is extremely hot and under high pressure–80 to 300 psi, depending on the environmental conditions. The condenser acts as a radiator, removing heat from the refrigerant, and in the process, changing it from a gas to a liquid.

Why does my Jaguar heater blow only cold air?

The flaps etc seem to be working, air flow moving around from floor to screen etc when selecting appropriate buttons – but air is always cold unless engine doing over 3000 revs (pressume extra pressure from fast running engine makes some hot water travel through heater matrix even if pump not running? – Does this indicate heater matrix is ok?)

Several people, including Victor Naumann and Harry Trafford, have pointed out that a block of wood positioned between the V and the top of the radiator can be very helpful to hold the compressor forward and above its normal position while you’re working.

How can I get hot air out of my Jaguar?

The way to determine this is to feel the heater hoses and if they are hot and then further along there is a cold area then that’s where the air is (which blocks the flow of coolant). The solution then is to purge the air by letting it out through a bleed point or temporarily loosening a hose clip to enable the air to escape.

Why is my jaguar’s type not cold?
