Also, does anyone have a fix for those little heater cable clips with the tabs that tend to break off? I tried rigging up some nylon clips held by a sheet metal screw but it doesn't work that great. hate to shell out $$ for all new cables and/or a new control box that comes with the cables.

The black one goes on the plunger side, green one in the middle

Here's the "YJ Heater Guide" for everything you wanted to know about the heater operations... enjoy

-------------------------------------------------------------------------------------------------------------------------------



When your controls are set to off

Your blower motor should not be energized, both vent doors inside your hood intake should be closed
and your vent door inside the cab on your passenger side should be closed



Driver Side-Closed



Passenger Side-Closed



Inside Vent-Closed

When your controls are set to defrost/heat

Your blower motor will now be energized with three speeds, the vent door inside your hood intake on the passenger side only will be open, and the inside vent will be shut



Passenger Side-Open



Driver Side-Closed



Inside Vent-Closed

The vacuum switch attached to the heater control has three ports. The hole closest to the plunger should have the black vacuum line in it. The second hole will have your green line in it. The third hole which is farest away from the plunger is left open.



You may have to tighten the switch itself up where it attaches to the heater control. If not the plunger may not be making contact with the heater switch.

I had to use new screws to get it tight as you can see here, this picture is taken from below the control




When the heater is in the Off position, the plunger should be pushed all the way in like this



Inside the hood vent intake; the passenger side vent is controlled by vacuum, while the driver side is cable controlled. If the black vacuum line is not connected to the switch on the heater control, the passenger side intake vent should remain open at all times.

Yea the same thing happened to me. I've had to do the copy/paste thing on other threads too, but rarely. We must have some security setting that stops them at first. What I do is copy and paste them into another web page that I have opened up, and then they miraculously show up on the other web page.

Great job Nitrox. You should submit this to Technical Articles & Write-Ups.
