FAN OF A JAGUAR S-TYPE 2000 HAS ONLY ONE SLOW

it usually put in on the low pressure side of any air conditioning system, it will be on the largest size alumunin line that comes from the compressor, some have a blue cap covering the service port.

it would be cheaper getting one from the junk yard. this is my link https://www.facebook.com/TedsRepairs

Removal

1. Drain the cooling system.
2. Reclaim the air conditioning refrigerant.
3. Remove the motor and shroud.
4. NOTE: Seal the line and the evaporator with plugs.

Detach the air conditioning line. Raise the vehicle.

NOTE: The splash shield is equipped with hinges which should be treated with care on removal. Remove the radiator splash shield.
Detach the securing clips.
Remove the radiator splash shield.
NOTE: Seal the line and the evaporator with plugs and Detach the air conditioning line.

1. Detach the lower coolant hose.
   
   
2. Remove the air conditioning condenser. Remove the securing screws.
3. NOTE: Vehicles with manual transmission, cable tie the cooling radiator
4. tach the automatic transmission/power steering cooler.

99 Deville - have you checked the large fan fuse(s) under and behind the main fuse/relay box ?? (I think this holds for 99 - 2000+ moved the maxi-fuses to the underhood box on the passenger side.)

Also, are your relays on a mount down near the fans ? Some have had trouble with the wiring/sockets there. 2000 or later moved the relays up to the fuse box itself. There are 3 - Fan 1, Fan 2, and a series/parallel (S/P) relay for slow and fast speeds.

Fans run in SLOW at 224 degrees F, FAST at 236 degrees F if there is no air conditioning or DEFROST function set. In the city or heavy traffic the gauge will go to the first tick mark past 12:00 and the fans come on. As the coolant lowers to 213 degrees F the fans turn off and the cycle repeats.

IF you set an air conditioning function, then fans run in SLOW all the time.

If your fans will not run under any conditions, check the large fuses in the underhood fuse/relay box, as well as the small fuses for the fan relays - there are 3 relays: Fan 1, Fan 2, and S/P (series/parallel): the fans are relay set to series operation (voltage drop) for Slow speed, parallel operation (full voltage) for Fast.

www.aa1car.com/library/ac_recharging This is a great web site to look at for your air cond. needs. It's easier for you to see and read than to explain the in and outs. It's very easy to recharge. Just remember to use the low side port which usually the hose will fit on to only one fitting to your air cond. You do not want to hook up to the high side even if it were possible.

Like a fridge Air con needs recharging ask if your local garage has the equipment

you have a bad blend door or just stuck

something is draining the battery just not sure what,

This sounds like an air damper is not operating, maybe a cable sticking or a vacuum line come off.

?? I also have 2004 XK8 with the navigation screen (Alpine). That isn't a touch type screen. The newer ones have a touch screen, but not that year.
You set the temperature (digital display) and the car will either turn on the heat or air conditioning, and speed up or slow down the fan depending on how close the actual temperature is to what you have set.
