Jaguar XJ-Series Heating/Cooling Issues
Hello everyone. I have been reading the boards to find out if someone has had any issues with Heat not working in XJ8. I own a 2001 XJ8 Vandenplas and the heat stopped working. I started to check items that I know would more then likely cause the issue. I checked the hoses coming in to the Heater core and the exit hose. I had heat one the incoming but not on the out going. I figured the Heater valve to be bad so I replaced it. Still the same issue(even though I tested the valve before installing it). I have the CD that came with the car (No Maintenance book) that says there is also a Motor ? that sends the water through the heater core. I have tested the voltage that comes from the climate conrtrol system to make sure it was sending the correct voltage for the valve to open and close. I guess the question would be: Could the Motor for the heater be blocking the path? The AC works perfect. Has new water pump and thermostat. The Temp sets in the middle range of the gauge. Temp sensor is new as it came with the plastic piping. (Hoping its not the climate controll inside the car)

i have the same problem, can you tell me were the heater valve is ? i can't seem to find it . thanks for any help.
Oh I replaced that heater valve and that didn't fix the heating problem. I dug further to find the Auxillary Heater motor was not spinning, it is located just in front of the Heater Valve. I am crossing my fingers that the one I ordered will fix the problem. Will let you know if it does.
And what drives me crazy, is that when i turn the switch on, the A/C comes on when it wants to, about half the time. And when it is hot here in Louisiana, we NEED A/C. Seems like an intermittent switch. Here we go again with electrical problems.
I will travel long distance to any southern states particularly to find such a tech and service facility. Texas, Louisiana, Mississippi, Alabama, Florida, Tennessee, Missouri, Arkansas for example. Do YOU know one? :surprise:
