Anyone know where the inlet duct is ? if i read the Gregorys correct it should be on the out side of the fire wall but i can't find it , it also has a green hose going into it and a Turquoise going into the heater control yet there isn't any Tu color house .I have put the green hose into the heat sender and it seems to work fine but the inlet duct where ever it is doen't seem to be working , any ideas ?

What are you trying to achieve?...I have the ford manuals here and can look it up ..perhaps the ford boffins were more clear...I have never seen a torquoise hose.

I am trying to rebuild my heater system at the moment, since someone(the previous owner?) butchered the system. As far as I can tell, the inlet duct is under the dash behind the glove box, and mounts on the front of the fan housing. And the green hose goes to a control unit at the top of the inlest duct that opens or closes the flapper for outside air or to recirculate cabin air. My inlet duct is not working, but I cannot figure out why as of yet. The vacuum lines in the engine compartment look like they were worked on by a shade tree hack. Unbelieveable mess.

I have recently removed the dash in my ghia and fixed everything so that the climate control works perfect now.

The inlet duct you can find by removing the glove box and the surround. The Turquoise (light green) vacuum tube is connected to the water tap and the (dark) green tube to the inlet servo which is on the side of the inlet duct. If the inlet flap is not working, it could be that the vacuum hose is loose or the servo is faulty. It could also be a faulty solenoid block ( ghia only). In my case it was a broken inlet flap. The flap has a small arm which is connected to the servo. This was broken. In got a replacement out of an Ed which had a lot thicker arm (improvement).

Also someone wanted to know about the spare black tube in the engine compartment? This is not connected anywhere in the fairmont ghias.

The inlet duct has a vacuum servo on the top to control the source of the air. And the linkage often breaks. So before you tear your hair out, stick you hand up the footwell duct and you can feel the flapper. If it moves freely, your linkage is broken, so you will need to buy a new duct unit. I paid $5 for one at the wreckers.

Thanks everyone for your help , at last i think i have worked it all out and fixed it up , it all seems to be working at last . The only prob left know is to some how fix the over reving when i leave the ISC in place . Any ideas ? The ISC is brand new , the Temp and Power steer sensors are all brand new yet makes no differnce .

does it over rev all the time when idling? or just sometimes? if its all the time, just bend the mounting bracket down slightly. when the engine is off, the ISC spindle should not be touching the throttle control arm.
