2003 Jaguar x type - No heat. AC works fine

SOURCE: 1996 Jaguar XJ6 heater does not heat. It just blows cold air...

All cars have what is called a heater matrix , this car has, it is inside the car behind the dash, the purpose is to provide heat in side the car, if the car is running at normal operating temp you thermostat is ok, the heater in the car is known as a heater matrix and will block up due to lack of use as water on passing throu when you have the heat on in side the car , hence the water leaves risidual that blocks it, if you keep a good level of antifreze/summer coolant in the systym it will prevent this, it is also the first palce to be affected when you lose water from the cooling systym, i will foward the detail how to clean it out, as removal is very labour intensive,

Has the vehicle overheated recently, if not there is a failure of the Coolant from engine valve controller, that measures flow through the Heater Matrix. Come back with more, as necessary.

SOURCE: My 1997 jaguar xj6 blows air but no heat. Can

the only thing that can change the air from hot to cold, or vice versa is the blender door. under your dash is a box which has 2 compartments. one with your heater core which is hot and one with ac which is cold. the blender door basically diverts which on the air in your car is being drawn from. if it is cold, air is moving on the ac side. if its hot, air is moving through the heater core side. if its warm, the door is in the middle. your temperature control knob is conecteted to an actuator, which moves that door. the actuator is a motor, but if it goes out, the door will be stuck on whichever side it is on. i would check that first. hope this helps

What could be the reason for heater not work on a 2001 S type Jaguar?


Hi, it sounds like the Blower or fan if you wish is not switching on. Check the fuse. If the fan is working and it's still not heating up, then it can only be a blockage somewhere in the water pipes of the heater, but you have changed the distribution valve, so I doubt it could be that unless of course you have forgotten to connect the steel cable to the valve or unless it is an electrically operated valve, then could be the current line to the valve is not connected, maybe a break in a wire or via a relay or fuse somewhere along the line, hence the reason for the valve being replaced in the first place. Typically of an electrically operated unit makes one think it's always the unit that is faulty, but meanwhile a simple connection failure caused by corroded bad contacts or a break in a wire(very seldom) is the real reason for failure.Just bear one important thing in mind...as a car gets older so will the electrical contacts in fuse boxes and relay fittings corrode or oxidize, that is why these components must always be serviced by cleaning out at least every five years, and, if you are living in a coastal area, at least every two years as oxidation and rust is more imminent..
I hope I have been of help to you,
Have a good day.

I have 2003 CORROLA 1.6 VVTI T3, DASBOARD, AC NOT WORKING


seems? (why guess?) (fuses are black/white deal)
3 non related systems failed, hummmmm
check fuses with a walfart $10 meter, on low OHMS> Rx1.
  1. 0 ohms is good
  2. infinity is bad.
fuses that look good, can in fact be bad. (hair line cracks)
so test them and avoid, SEEMS?
Rear glass heater is a hot wire heater.
if it has 12vdc to the wire and no heat the grid is bad (open)
if no 12v there, then the relay/fuse or switch to it is bad,
the voltmeter finds this in 5min work.
Hazard not working (but are blinkers> dead? on either sided?)
again fuses.
Dash board dead, (cluster) FUSES.

A.C. not working (the FSM and alldata.com cover this)
1: fuse , check fuese
2: if heater fan is dead, so will be AC.
3: A/C clutch not engaging for 6 reasons , ask. for list of tests.
all tests are in the FSM. BTW.

my wild guess, is you are working on car that has not run
right for a long time? accumulated, issues?

No heating takes place when turning on the climate control, both automatic and munual??? This just happened without any warning. What could be the cause?


Lots of things - start with
  1. does the control panel look correct - no strange info and the settings will change, everything switched on- relevant fuses checked?
  2. check for signal to heater water valve, does valve move (make noise)?
  3. have you lost coolant recently - possible airlock to heater matrix
Hope this helps.

This may be as simple as some cells in your car battery being knocked out. Try a jumpstart and if this works then it is the battery.
