yeah sometimes i shy away from them on here.. more of a hands on diagnoses. but love to do them too.

 

Hi sorry been so long but got fed up and went on holiday for some warmth lol. Hose temps the same on both sides now that i changed the thermostat and top hose 1 of the fuses had blown but i changed that 1 it was under the cover in the engine bay. i think i'll sell up and buy a range rover

 

Jeezy Peeps! Frying pan and fire come to mind

 

Sorry mate. Wish I was there to help. Hard being an ocean away and trying to help.

 

not to worry thanks for all your help

 

Hi guys thanks for all your input did all you said changed the valve, changed the panel, changed the thermostsat and top hose( cause i broke it) flushed the system, changed the fuses and finally gave up and rang jaguar and spoke to 1 of there tech guy's who then told me that jag have found a fault with the wiring so here it go's
THIS WHAT HE TOLD ME BEHIND THE FRONT BUMPER ON THE S TYPE IS THE MAIN WIRING LOOM IN THE LOOM ARE THE WIRE'S FROM THE VALVE THESE WIRE'S BREAK AND CAUSE THE HEATING TO STOP WORKING MAKING IT LOOK LIKE THE VALVE IS AT FAULT BUT IT'S NOT, YOU HAVE TO FIND AND REPAIR THE WIRING AND THEN THE HEATING SHOULD WORK. so anyone with an s type heating problem try this and see if it work for you. p.s it 1 hell of a job to do so good luck. p.p.s i have heat at last hooray!!!

 

Lol glad to hear it.
Only time I see that problem is when car been in accident causing damage.

Now the heater system will probably outlive the car.

 

i have seen it once as well, and no noticeable body work had been done
the o/c was in the conector itself

 

Yeah I have had the oc at connector from coolant having leaked and corroded it out, but never behind bumper unless in accident.
Easier to overlay harness at that point LOL

 

up here in canada we do a lot.. had couple cause heating problems.. but mainly lighting.. problems.. wiper problems.. have done 2 front harness on the same car within 2 years.. are salt up here is really bad..

 

I think I will stay down here in paradise thanks! LOL

 

Hello everybody,

Sorry to raise this old topic. I have a "cold air" problem also.
We've repaired DCCV, now "out" hoses are warmer then the "in" hoses, reved the engine in case there is an airlock, but still no heat.
What problem could it be? Wiring? Heater core?


Thanks and sorry for bad language

 

Oh, and one thing we can't understand is that wiring keeps valve closed, so if the wiring is damaged it can't keep valve closed - there should be heat. Or is it working another way?
