What kind of air con does a jaguar have?
It also controls air direction to dash top (screen demist), dash front (corner face vents), centre vent, and low level vents front and rear. The systems were designed by Delanaire and the early cars (up to ca 1987) used the Mark 2 system, and later cars the Mark 3.
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 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.
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.

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.
Why is my air con leaking in my Jaguar?
Accordingly, when there is a leak, the area usually looks wet with oil. This is a large ‘radiator’ mounted in front of the engine coolant radiator, which cools the hot refrigerant gas enough to cause it to condense to a liquid. Due to its position it tends to be most damaged by stones thrown up from the road and by corrosion.
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.
Where is the Air Con controller on a Jaguar Mark 3?
On the Mark 3, the controller is a small computer which electronically operates the flap valve motors, blower fan speed and vacuum solenoids for the external vacuum ‘motors’. This computer is diamond-shaped about 5 inches long, located on the right hand side of the airblend box.
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.
Why is Jaguar S-type running rough at 3000 rpm?
Restricted performance and running rough at 3000 RPM. I have an OBDII code reader and found that the problem was in the air mass flow sensor, which is just after the air filter.
What causes a jaguar’s type restricted performance light to flash?
2003 jaguar s-type restricted performance at 3000 Rpms. car sputters. I replaced the plugs, and coils to no avail . the check engine light flashes with the restricted performance. has around 108,000 miles. has anyone else had this problem and what caused it ?
