have you had a chance to check the vac system? Esp to the bulk head by the heater pipe, and elbow on top of the hbv?

Hi.

No hot air in car could be number of things ?.

1. have you or anyone being working on the coolant side of things lately, and perhaps got air trapped in the system ?.

2. when the engines at working temp, are both top and bottom radiator hoses hot / warm at all ?.

3. Does you fan work on all speed settings or just 1 or 2 ?.

Take it as you say vent selector isn't working you don't have electronic aircon ?.

4. does car show at normal working temp on gauge ?.
If not, or doesn't every show working temp, you could have perhaps sticking thermostat ?.

Can you describe any other systems, that may help ?.

Don't know if any of the above will help get you started ??. :-?

help me please

when you move the vent selector with the ign off can you here hissing as you turn the vent direction control? you should also hear the flaps operating as well

turned out to be vac pipes where set up wrong and the heater matrix needed a dam good clean out

all is sound now mate

3 i have the full range of fan speeds ie 1-4 and yes its the non electric air con

4 the temp gauge works well

there is no hissing sound and no noise of flaps moving. with ign off or in position 2

[kingplym]

i meant to add that i just noticed that two pipes passing thru my bulkhead high leve; rear left of engine bay have been cut and a small copper pipe fitted. as to by pass going thru the bulkhead and into the cabin?

dont suppose this is relevant? :-?

from what i gather the vent motors and mixer flap :-/,  are vac operated  if the vac system aint right, good chance its related.

Sounds extremely relevant!  It sounds like someone has deliberately bypassed the heater matrix so no water goes into it.  Only one possible reason for that - the heater matrix leaks.    You could try reconnecting it and see what happens, but my money would be on you being ankle-deep in water.

Having only had my own Miggy for a month I can't tell you how easy it is to get the matrix out - it depends on the bloke who designed the car.  (On the Cortina you undid two screws and it was in your hand, on the Sierra you took most of the car apart to get at it.)  Others on here should be able to tell you, or you could ask that nice Mr Haynes!

just had look at what mr haynes says and it looks like i gotta take the dash apart and steering column supports. oh what fun!

think im going to try re-connecting and maybe go for a swim ill try n update what happens

Have a look at the colour photo here http://www.omegaowners.com/forum/YaBB.pl?num=1152565204
Although the top pipe has been removed, do you mean that these pipes have been joined :question
