Why is my Jaguar X type air conditioning not working?
The dye normally shoes up under UV light. This will show any possible leaks. When this is done the nitrogen will then be released and any repair taken care off. The system will then have a vacuum pump attached. The vacuum servers 2 purposes, one, it pulls out all nitrogen and or system gas.
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.
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.
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.):
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.
The dye normally shoes up under UV light. This will show any possible leaks. When this is done the nitrogen will then be released and any repair taken care off. The system will then have a vacuum pump attached. The vacuum servers 2 purposes, one, it pulls out all nitrogen and or system gas.
How does an air conditioner compressor work in a Jaguar?
COMPRESSOR – The A/C compressor pumps the refrigerant through the system. It’s operated by an engine belt, just like the alternator and power steering pump. The only difference is that the A/C compressor has a clutch that engages and disengages the compressor as needed.
Where does the refrigerant go in a Jaguar?
Let’s follow the refrigerant’s path, once it leaves the compressor: 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.
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.
