Having the same problem with my 02. I am about to change the blend door actuator that controls the "door" that controls the amount mixture of hot and cold to make the desired temperature. I will let you know the outcome.

Hi, The most common problem with the cJaguar s type not blowing warm air from the heater vents is the electric valve that has on some models 5 pipes coming off it or later models 3 pipes, they tend to cease up, I have just done mine and mine was a January 2001 model with 5 pipes, very easy to check, the valve is in the front of the car drivers side, the quick release clips are bit of bugger to slide but you can always change to jubilee clips, the 3 metal thin pipes make sure you still have the O rings and they havent fallen out the pipes when you take them off, the electrial connection pull up the red sleeve then work the plug off the old valve, I kept the hoses on the valve and disconnected easier places on the engine, when I took off the hoses off the old valve I put the hoses back one by one onto the new valve the same pattern as the old one which is important as they are of all shapes, then put your unit into the car do your 10mm bolt and nut back up and fit back what you took off, the top hose to the radiator is a must to disconnect to get access to this valve by the way, also do the job from the top of the car, when you have completed fitting refill with coolant antifreeze and bleed the system which is a little turn screw on the front of the engine connected to a water pipe very easy to see, also when you have let the car heat up give it a rev to shift any airlocks which I had on the heater, , first of all I got worried it wasnt getting hot but after the little rev the heating started to work perfect, the job took me 4 hours but then I am not a mechanic but the clips on the hoses took me a while to remove , hope this helps anyone
