Hi all,
We're putting the interior back together and of course we have to have the demister working for rego etc but just can't seem to get it right.
We get good heat and the blower fan can be turned up and down but the air is only coming out from the floor/under the dash. When we slide the VENT/DEMISTER/FLOOR slider up and down nothing happens.
I've checked all those vacuum hoses that go from the 3 actuators up in the dash to the valve switch behind the heater controls and I'm pretty confident they're all where they're supposed to be. The vacuum line (no#4) is coming from the T piece on the engine manifold so I think that's ok too, but still the vents don't change from floor to demister etc.
I can reach my hand up and push on one of the actuators and then the heat flow changes to demister so there's no issue with the door actuator(s) I would think.
Another possible issue is when we reinstalled the 5 litre we decided to do away with all the aircon stuff. Brother didn't want it so we just removed all the compressor, lines and related stuff. When we removed the aircon lines from where they connect to the firewall (below the fuse box), we have just left those 2 connections 'open'. Seeing as though the heater doors/actuators work on engine vacuum, is it possible the vacuum is escaping the system because these 2 aircon outlets just vent to the atmosphere? I'm not that cluey on the aircon system so I'm not sure if removing that aircon stuff will affect the heater controls - it's just a thought.
Any thoughts or test ideas would be much appreciated as it's about the only thing stopping us from putting it all back toegther for rego.
Cheers
