    Ok, I am missing something....Is your Z missing the cables altogether? or are they just disconnected?

    Are there any loose cables near the selector levers on the front of the Heater Box or on the sides of the Heater Box?? If so, you can look at the FSM and reattach them. If the cables are gone, then I am sure that you can find some on this site. Make sure to list your year model.

    Good luck.

    I agree with Andrew. Look for the cables. Sometimes they will come off the clips. If you need new ones, try Zcar Source. They aren't cheap, but I've been happy with the quality of used parts I've received. They also are prompt on shipping.

    This is a pic of what the cables look like behind your controls. I have to get the FSM to tell you which goes where. I forget.

    That picture is missing one of the cables.

    There are FOUR cables in a 240 Heater Control.

    Yep, the one on the upper right hand corner, where the empty clamp is located.
    But I am sure Zedyone_kenobi was just showing the picture as a reference.

    I just sold a complete setup on ebay for $10 bucks. The cable connections are pretty self explanatory. Feed them out the back of the console and attach them top right to top right connection, bottom right to bottom right connection, top left to top left connection and bottom left to bottom left connection. they are all different lengths so it is pretty easy to figure out. Get on your back on the floor boards with a flash light and a phillips for the easiest approach.

    It is attached to the center console. You should download the factory service manual here: http://www.xenons30.com/reference.html

    It will walk you through it.

    You will FIRST have to disconnect all the cables. This is beneficial since it will teach you where they are and what condition they are in. then it is a matter of taking out the light above the slider controls, and then the two screws that hold in the panel. You will have to disconnect the knob on the fan switch as well. But it is pretty straight forward.

    And yes, I had already removed my 4th cable now shown in the picture, but good eye!

    I looked through the manual but it doesnt specifically tell you how to remove it. I ordered the Haynes Manual so hopefully that will serve its purpose.

    How do I remove the cables? Should I disconnect it from the HVAC or from the other end? I'm afraid of cracking or breaking these filmsy plastic pieces. Yesterday I made a slight tear in my lower steering column cover cause I didnt see there was one more screw buried deep inside the cover.

    You remove them from the piece of hardware it controls. You cannot possibly get to the back of the heater cables on the center console before you remove the center console. Good Luck

    is there a backside picture of the heater switch?

    the two cables in the backside of this snapped off. i'm trying to see if there were circular clamps to hold the cable housing in place like it does on the topside. if it does, i'm screwed cause mine is missing them.

    In the picture you re-posted there is a pretty clear shot of the Heater Switch. It is the electrical component on the lower left of the pic.

    There are no cables that connect to the Heater Switch.

    Does that clarify things?
