How does the Jaguar air con system work?
There is a thermostat inserted into the evaporator matrix which switches off the refrigeration compressor when the matrix approaches freezing point. This is to prevent icing up which would stop air flowing through it. On early systems this can be unreliable.
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.
What are the faults of a Jaguar Mark 2 air con?
The vacuum valves on the Mark 2 can also become clogged with dirt. The condensate drains can become clogged. See faults below. On the Mark 2 this is an assembly of a small electric motor with servo feedback potentiometer, and a shaft carrying a number of cams, positioned under the airblend box on the right hand side.
Can a car air con compressor be damaged?
Compressors can be damaged through overheating if the refrigerant falls below a certain level, so they have a device to stop their operation under fault conditions. Early cars (up to about 1988) used the A6 compressor with a high temperature switch.
Why does my Jaguar A / C not work?
The problem: These vehicles have been found to exhibit poor air conditioning performance thanks to a worn-out air conditioner compressor direct pressure sensing valve. When this valve is bad, it results in misregulated refrigerant pressure, affecting air conditioning performance.

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 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.
