I spent too much time searching and watching YouTube videos and I'm just not clear. My slider isn't working because the cable doesn't move at the valve when you actuate the sliders so I'm trying to manually put it in closed. I'm not sure if the cable pulls to close the mixer or if the cable pushes to close the mixer?
This is the mixer valve on the firewall behind engine that blends in hot coolant to the heater core I assume in the dash.
the armature that moves has the position stamped into it. Cable tight to the firewall is closed for mine, away is open.
My truck is RHD, Part number is 87240-60160 for Valve assy, water
Do they ever fail in such a way that coolant will still flow through when it's in the closed position? I feel like no matter what there's some heat being put into my air conditioning.
The condenser line under the hood is very cold but the condenser doesn't drip water like you would expect.
Mine has the full separate rear AC which actually works well but the front seems to have warm blended in with it.
That interesting. I didn't see any markings on mine but did not remove. Experimentation seems to indicate opposite of what you said. When cable pulled in to firewall the output side gets hotter than when cable pushed away from firewall.
possible that the armature broke from the ball inside, pull the cable off and see if you can move it by hand, there should be a good amount of resistance.
I think I'm going to have to figure out how all the various air flaps and diverters and such work as well. Since the condenser is not dripping I feel like the hot humid air is not going through it.
I was using wrong term. I was calling it the condensor but what I meant was the evaporator. The evaporator hose where is comes through bulkhead is very cold but it does not seem as if the air is going across it as there are no condensate drips below car.
Okay I checked the evaporator in the dash and it's actually very clean it must have been replaced sometime before I got the rig. But I was wrong about the evaporator getting cold it's actually the exit line of the evaporator that's a little cold because The line from the rear evaporator comes in and it still cold enough that the metal gets cold around that whole area.
Anyway the point is evaporator is not getting cold.
I have a new mixer valve on the way but for now I pinched off the hose but that's not the problem.
I don't really know HVAC that well but since the rear AC works perfectly I know the compressor and condenser are working.
I have to figure out where how the two systems split and see why one side's getting cold and the other is not.
I know that at least with my 80 and it's fully mechanical climate controls, the hot-cold adjuster has two cables - one to the airmix damper in the airbox (which is what I think is broken in the airbox on mine) and the heater tap in the engine bay. I can't get the hot/cold to go all the way to cold because of the airmix damper issue.
On 80's with any sort of electronic controlled climate settings I don't know if the same two cables are present or not. My 80 has had no working AC since before I bought it in 2011. My AC is opening the windows.
