Temp gauge is just below half, all pipes are got except the out feed from the bulk head, and air coming out of the centre inside are all cold even with heaters set at full and hi, and tried in all variations with no difference in temp.

What exactly do these do anybody know.

Looks like this is what drives the direction of the air to the vents, and whether it's hold and cold. I shall investigate this part as well as reading it appears it's visible when they're not working correctly.

Have you had the stereo unit out at all? It is an easy thing to do check the all the wires are in properly.

Loads of how tos on utube. Keep us informed i am on lots of forums so see what i can find out for you.

[Aroper2003]

No, I haven't had the stereo out. 

If you do hear or see anything about the heaters not working in the mean time I would be grateful.

Thank for the help so far.

This guys heating did not work on a vw group car. He goes in depth why he had no heat, im not saying cut the car up just look at why it did not work.

No im not saying you have. But if youve had no heat since buying the car there is a reason for it.

[Aroper2003]

The heating was working until the trouble started with how it was running.

[madasahatter]

Check your fuses then mate some under dash and near Battery box. Do you have a hand book? If so look in there mate.

If pipes not getting hot as water is not being pumped round engine so could b thermostat, just take it out put in hot water that is one way of checking thermostat if it works.its worth a shot

I don't think it is the thermostat personally.  If it was stuck closed, the engine temperature would be affected.

That, along with the fact you have just drained the system, suggest to me that it is an airlock in the matrix.

If you squeeze the radiator hoses, does the fluid level go down?

I agree, the water is getting pumped around the engine system and I presume coming through the thermostat to heat the infeed to the heater matrix, it's just not coming back out ( unless I've got the system of water flow wrong)

 

If I squeeze the hose the water goes up and down with the pressure as I'd expect.

And if the stats stuck open water will not get to the right temperture.

I agree, but the water is getting up to the right temperature, as the temp gauge is in the right place and it certainly will be hot after being running for an hour.

Not sure if is still valid or not, but in the old days we used to run the car pointing uphill to try and force the air out.

[johnatg]

Certainly sounds like an air lock.
