I have a 2005 Jaguar S-Type 3.0 The A/C was working fine then all the sudden the passenger zone started blowing HOT air and the driver zone started blowing cool instead of cold. both zones were set at 65. The air works great at first start-up until the car heats up of course, so I know that the A/C is ok. I was told to change the heater control valve, I did but I still have the same problem. My question is......Is there any components(fuse or relay) between the control valve and the control panel in the dash? The control valve must not be getting the signal to close from the control. Please help!!!!!

There are three probable causes of this problem in order of probability. water control solenoid valve air con control module wiring loom fault at front of car The valve can be removed and tested as this has solenoids that can fail. the air con module can be damaged by the valve failure. If you open the module the most common fault (easily seen) is a burnt out section of printed circuit which can easily be bridged with fine wire soldered in place I fixed my unit this way saving 300 This unit is vulnerable due to not having fuse protection in the case of a solenoid burn-out ! The wiring loom is a break in the signal wire to the water control valve normally found on earlier S Types. Hope this has been of help - good luck.
I have a 2005 S-Type 4.2 and had the same problem; mine also has the dual temp control as well. Anyway, I was told that there is a solenoid in the coolant system that is not closing properly and the heater core is receiving hot water continuously, fine when the engine is cold and explains the onset of hot air once the engine warms. This occurred for me while under warranty, so I can't comment on costs for P&L, but with this info, you may be able to shop it around or search for other solutions.

As far as your a/c issue, this sounds like a common problem of low refrigerant charge in the a/c system, most of the cars with dual climate control will blow cool air from passenger side and warmer air on drivers side when the refrigerant level gets too low. I would suggest taking it to a repair shop and have the system checked for a leak before you try and have it recharged... and as far as the motion sensor issue, this may be a module that is faulty or a sensor that has failed, either way it will have to be looked at by the dealer or a shop that has a proper scanner to check the sensor and module status... hope this helps
it is more likely the wiper switch has bad contacts or the washer pump is defective, go to the pump and have someone hold wash and check for a 12 volt sigal at the washer fluid pump, if no siganl replace the wiper/washer switch, and if u do have the signal at the pump then the pump is defective.
the problem would be the wiring on the door, possible a break in the wire, therefore the window and the central locking isnt working, possibly the earth wire is broken, open the front passenger door and u should see a sleeve connecting to the rear door, that is where the wiring to the door is, check ! also i would check the fuses. thanks
On the passenger side of the engine compartment near the radiator you will see a coolant control valve that has heater hoses running from it to the heater core inside vehicle.This is probably going bad.You can clamp off the hoses with some pliers while it is acting up and see if this stops the heat.If it does then it is probably bad.
You can rent at basically no cost a brake rewind tool from Auto-Zone (at least the one by me let me do it). You need to apply pressure while turing clockwise on the passenger rear side, and applying pressure and turning counter-clockwise on the drivers rear side. Good luck. My experience tells me these can be a little stubborn. It just takes time and a little pressure.
