Ok my zeds heating has completely stopped working it doesn't blow any air out at all I have checked all the fuses and all is fine and there is no leak from the matrix as far as I can tell by feeling around to see if the carpet is wet does anyone have any ideas it's fooking freezing

Do you mean the fan is not running? try overriding the auto feature by pressing the high speed fan button, if it is not running there are two fuses in the drivers footwheel, there is also a drop resister unit that can fail, that is located behind the glove box. If however you mean the fan is running but not hot air it could be a problem with low water level or an issue with the matrix valve.

The fan is running in the engine bay when the engine is on but there is no air hot or cold coming out all the fuses are fine as I have just rechecked them all the car is full of coolant in the rad and bottle as I topped up everything this morning :s

Which fan phil? Are the blowers blowing at all?

Heater fan resistor ?

The blowers are not blowing at all

I will check the fan resistor tomorrow when I can see a little better cheers buddy for the eBay link :)

ok just clarifying, might be worth popping out part of the under dash to feel the matrix see if its warm but no airs blowing or weather its not not even warming up.

if its the heater fan resistor which is the problem, let me know i will finish the auction rolandas put up early

Could this be caused by the thermostat being stuck?

No, although the engine would run cooler and so would the coolant going through the heater matrix the fan should still operate.

Thanks Jeff, good to know...

 

Edit : D'oh didn't see the bit about the fan, really should read better.

If you find its the heater resistor which you need to take the glove box out then its held by 2 philips screws and a block connector going to it..front facing you cant miss it. Anyway mate i have a spare one you can have for free:winkiss:
