I have had the same problem for quite a while now. In fact, my wife does not want to drive the car anymore for fear of inhaling toxic gases.
Anyway, I have a '03 6cyl w/ 69k miles. I have had it worked on by my own mechanic for this issue and apparently it hasn't worked. It seems to happen after the car is warmed up and you can actually see smoke coming through the vents. It is very frustrating, considering I have spent $300-$400 to fix it and it is the same.
 
Any help will be appreciated. Thanks

Loving my this car...what a beast...noticed however that a "bubbling/gurgling" sounds sometimes comes from under the the dash... especially right after the car is turned off. Any ideas?

I too had a 2004 4.2 v8 that bubbled and gurgled now and then when hot or cold .
Some one told me there was a purged valve on the radiator that had an air lock.
I never had it fixed but it was annoying at times

Hi
Jaguar S Type - 2.7 Deisel - Reg 2006
 
Re your posting Nov 13, 2009 - Heating problems.
I have exactly the same symptoms as you. Could you tell me what the problem was, and how much did it cost to repair.
 
Symptoms - semi cool air blowing from centre vent driver side - warm air passenger side - temperature control and air con do not work. Checked gas level - All OK
 
Look forward to hearing from you.
 
Many thanks Peter

I had warmer air in some of the vents on my 04 Stype v8,,, simple fix with a sensor.
I think it was a couple hundred bucks, I'm going to see if I can find out waht it was I no longer own the car

Any ideas what the problem is, and cost to repair.

nwjag,
The Climate Control Module has a tendency to burn out, but it is not due to the act of replacing the heater valve. The burn out is most likely caused by too much current / power draw from the old/defective heater valve (which is wired directly to the Climate Control Module). By the time the new/replacement heater valve is installed, the Climate Control Module has already burned up.
 
I'm an Electrical Engineer with background in automotive electronics product development, and I wasn't about to pay the dealer a four-figure sum for this when it happened in my own S-Type. If you haven't already replaced that Climate Control Module, I can diagnose and repair it for you. Let me know if I can be of assistance. E-mail me at this dedicated address I've just set up: jaguarclimatecontrolgmail.com

Thanks for your reply on Edmunds Forum.
  
Would appreciate any help - According to Service Manager at Jaguar is most likely to be a broken wire !!
  
Whats your view and cost to repair?

For anyone else that may have a damaged/defective Air Conditioning Climate Control Module in a Jaguar S-Type, here are some guidelines and solution(s)...
 
Symptom(s):
1. Driver and/or passenger vent(s) blow(s) hot/warm air, even when the controls are set to max cold (or any other level). This may occur on just the driver side, just the passenger side, or both sides, and even intermittently.
 
Causes:
1. Only the Heater Valve (or "Coolant Control Valve") is defective. After some time, corrosion and vibrations cause this component to fail, either mechanically and/or electrically (i.e. internal short).
-or-
2. Heater Valve + Climate Control Module are defective. When the Heater Valve dies or begins to die, it eventually takes the Climate Control Module with it to the grave.
-or-
3. Only the Climate Control Module is defective. Assuming the Heater Valve is good, this particular scenario is unlikely to happen.
 
Why the Heater Valve gets damaged:
Corrosion - not enough anti-corrosion additive in the coolant, or harsh weather conditions, or just old age? Vibration?
 
Why the Climate Control Module gets damaged:
There is no protection circuitry in the Climate Control Module to protect itself against damage due to failure at the Heater Valve.
 
How to diagnose:
1. Check the fuse for the Heater Valve. It may be labeled as "Coolant Control Valve" in the owner's manual.
2. Check the connection to the Heater Valve. Is the connector loose/corroded? Is the Heater Valve corroded? The S-Type is an always-hot-fuse system, which means that one wire to the Heater Valve is always "hot" (+12V), and it needs the other wire(s) to ground to chassis in order for the internal solenoid valve to work. Replace the Heater Valve first. If you have replaced the Heater Valve, but still experience the above symptoms, the Climate Control Module has probably been damaged already.
3. It is probably not the The Evaporator Discharge Temperature sensor(s) under the dash, but check them anyway.
4. If the dealer has replaced everything else besides the Climate Control Module for you already, then the last piece of the puzzle is probably the Climate Control Module. Gotta replace or fix it!
 
What I can do for you:
You send me your Climate Control Module (complete unit, inside the casing with front faceplate). If you cannot remove it from the vehicle yourself, I recommend that you have a qualified technician do the removal and later re-install for you. I will diagnose it at no additional cost to you (besides what you paid for shipping to me). Once I have confirmed the presence of repairable damage, I will give you a reasonable quote for the repair including return shipping back to you. Not only that, I will modify your module with protection circuitry that will prevent it from getting fried again in the same way (the next time your Heater Valve dies). If you happen to have the old Heater Valve ("Coolant Control Valve"), I can bench test that as well, but it is usually not repairable when the internal and sealed coils are damaged. Send me an e-mail to discuss your particular case: jaguarclimatecontrolgmail.com
