Question about 1996 Jaguar Xj Series
I can't get this old Jag to heat up, but don't want to spend a fortune on repair...What is the most likely simple/cheap problem, i.e. faulty switch or something?
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,

Check out the auxiliary water pump - it is located on the left hand side under the bonnet near the bulkhead.
Here is a link on the repair :

The problem is that the heater pump has failed. This is a small electric water pump that's near the brake master cyl. This circulates water through the heater core. ANY Jag mechanic should know this !!!! These things are about 200-300 bucks.
