Question about Jaguar Heating & Cooling

1 Answer

I have Jaguar S-Type 2000, and I am facing a problem in the Air Conditioning System. When I switch On the A/c, the compressor sometimes works and sometimes no. Also sometimes it works for a while, for a short period of time and then it goes Off. I replaced the (Relay), but the problem remains. I hope you can help me defining this problem. Thanking you.

If it is low on Refrigerant, it will cycle the clutch off. When the pressure rises from the lines equalizing, it will come back on. When it does stay running, does the larger line get cold? If not, it is probably low on refrigerant. Roger

Solenoid that affect the heater

The heater is controlled by a 'variable solenoid water valve' that is controlled via the Air-conditioning module. These valves are prone to failure after a few years service. Another cause is if you have refilled the cooling system, the heater matrix sometimes airlocks, this can be overcome by bleeding the hose at high level by the heater hose in the engine bay.
Good luck -hope this helps

Air conditioning problems

First check that all electrical connections to/from your air conditioning components are tight and secure with no broken or chaffed wires and connectors, or oil swollen connection points. Then check that all fuses and relays involved in the operation of your air conditioning system are operational. If all is good, then remove the belt around the air conditioner compressor pulley. Get a wrench and try to turn the front of the compressor pulley. It should turn with little to no resistance. If it wont move or is very hard to turn, it is probably locked up and needs repair or replacement. If it moves, then the compressor part is OK, but your clutch would likely need replacement. Some model cars its cheaper to just replace the whole compressor than to rebuild the clutch. Jaguar sounds expensive - I would seek out a junk yard. Good luck.

    Noisy air conditioning pump

    Hi guys,
    I have a 2.0 diesel X type and when the AC is switched on and the centre of the pulley on the compressor goes around it sounds like there is a very noisy rattle from the engine. It is OK when AC is not on. any ideas, and can this be fixed without replacing the compressor.

    My air conditioning was blowing only hot air. The dealership replaced the AC compressor. It worked for one day then started again blowing only really hot air. It has not had the problem diagonosed yet...

    It should have been diagonosed already if you had a compressor installed, They are to check for leaks, and should have replaced any bad o-rings,
    When the system is vacuumed (a mechine applies a vac. to remove any moister in the system) it is to sit for min. 15 minutes with pump off, any if the gauge shows that vac. has changed (should be a neg pressure) then there is a leak.
    I would take it back, but I would only pay for parts.
    Check out this site and maybe it will enlighten you how A/C systems work. Good luck
