can anyone please help me, i have an 88 EA fairmont giah and i am having trouble with the climate control. i have 2 black and 1 green tube coming through the firewall but not connected. can you tell me where they go. RAY
One black one does nothing in my car it is connected to that vacuum pressure lines thing behind the glovebox but is blanked off in the engine bay, the other black one goes to the heater tap, follow the heater pipe down and you should find one, the greenish one goes to the inlet manifold for vacuum presure.
Someone may be able to provide a pic to show exactley what goes where, but I hope that helped a bit,
The way you've described the hose routing isnt correct.
The Green goes to the heater tap.
Long Black one goes to the Vacuum fiting on the Inlet manifold. On CFI this is mounted on the top of the manifold directly out from #5 port. It should have a Tee peice with another pipe going away from it hooking up to one of the ports on the PVS valve
The Short Black has a check valve and another bit of pipe going directly to the PVS valve.
The PVS valve is located on the thermostat housing and has 3 ports. There is a rubber fitting which has one port blocked off and the hoses simply push into the other 2. It doesn't matter which way round they go.The PVS valve is there to switch the aircon onto recirc mode when engine overheating is immenant. This reduces the load on the A/C system.
NZ - yes you are right, i got it backwards, light green heater tap, and black one to inlet manifold, and thanks for letting me know were the 3rd one goes, might have to look into connecting that one back up, but by the sounds of it not really needed.
NZ- um no, i merely mistyped, i have mine connected correctly and all works fine, heater blows hot, and the a/c well it needs gas, but i will replace almost everything when STOKEB gets back online and confirms what he is selling was all working before he pulled it out (not convinced mine was so good to start with)
