I hoping someone with an early FSJ has a fix for the heater contols. I have searched everywhere and have come up with nothing. Here is a photo of the piece I'm talking about. I've cleaned everything. The two metal disks leak enough so that it won't control anything anymore. All the hoses are new/good. There is good tension on the spring. Is there supposed to be a gasket? Are they supposed to be machined so close as to not need a gasket. What am I missing?

I'm not sure about a gasket, but try a little solder...or JB Weld. (Try JB Weld first). Or, that almost looks like a 70-early 80's type pushbutton deal mounted sideways, instead of level like on later rigs, might be interchangeable??? (like maybe you can take the pushbutton assembly off a later rig and mount it sideways in yours...I'm not entirely sure of this, as I've never seen one personally save for pic's like yours.

I agree with JeepBountyHunter in that it looks like a vertical mid-70's. Where your finger is, is that the vacuum switcher to the air doors? If so, might be the same as mid 70's. And you can get one from a junk yard.

Easy stuff, CLEAN and LUBE. I just took this one apart to show you what you have. Pretty much the same steps as shown below

Thanks for the replies.
Yes carrotman, that does go to the air doors. Holy cow Crazy_Jeepman!! Thanks! I didn't try vaseline. I was thinking of using marine grease. It won't run when it gets hot it there. I did use some 1000 grit sandpaper and a granite block to make sure I was sanding on a flat as possible surface but I still can hear the woosh of air while just sitting at idle and it's enough so they won't function. I don't think I can get those two surfaces any smoother without som precision milling. I'll have to try though. Yes, I did put a vacuum pump on the canister, it holds perfectly. Good line, good canister. I'll have to try the local boneyard. There's a couple late 70's out there that may have a "used less than mine" piece on it.
I was looking into a way of getting rid of the vacuum all together, if I can't get the original working, by adding micro-switches to the back of the unit and changing the canisters to electric ones or some small solenoid. I don't think these were meant to last this long otherwise they would have made a better design. It is quite simple and probably was very cheap.
