    Am I able to remove the knee protector bar before I remove the rest of the dash? Or should it be done after?

    Car had been re-upholstered when I bought it and now I’m fixing all the BS mistakes. Ugh.

    Remove the knee guard first. the only way to remove dash. I posted before on dash removal. the knee guard has 6 or 8 bolts 13mm some vertical. You have to pull the speaker panels out to see them in the corners.

    Thank you, David. Fwiw the reason why I'm going through all of this is because the dealership from whom I bought the car had the dash and seats redone. Unfortunately, the upholsterer was not terribly concerned with quality and there were a lot of wires that were pinched or severed or mis-routed in the process of reinstalling the dash. In addition they installed the glove box wrong so it wouldn't fully open.

    I've got a few weeks with the car in the garage so I figured I'd use this time to solve all of these problems and get the interior fully up to snuff. Ok, so now I'm at this stage:

    Here's my new issue- I need the knee panel out so I can install the glove box back in and check out some other wiring behind it. I've removed the 13mm bolts that hold the knee panel in place but it seems bound up by the cluster set that holds the digital clock, fuel meter and oil temp. Does this have to come out? If so how?

    With difficulty? :( It's been way too many years since I did this to recall exactly, but I think you've got to remove the seats (just to not maul them), then the central tunnel starting at the rear - hinged box, then seat belt panel, then instrument panel, then central tunnel carcass, then you can get the center instruments out, then you can get the knee pad out, then you can get to the upper dash carcass and the glovebox. It was/is a terrible design for servicing...

    OMG please say its not true. I'll figure out a way to get that damn glove box back in, I got it out without removing the knee pad. UGH!

    Steve's right, the central tunnel needs to come out (or at least be completely unbolted and the rear lifted up) to gain enough clearance for the knee bolster to be lowered and removed. The hardware circled bolts the central tunnel to the knee bolster. Image Unavailable, Please Login

    Good news, glovebox can be reinstalled safely without the knee guard removed so long as you remove the vents located below the radio. What you do is install the glovebox with the left hinge at the same time.

    The bad news is once reinstalled I learned that my glovebox light microswitch is missing the metal lever to depress the plunger. Ill be buying a new one.

    I assume this switch is NC, so when the glovebox is open there is no pressure on the plunger and the lights turn on. Could someone confirm?

    It can sometimes be a little confusing to use NC or NO because the definition of what's "normal" - for example, is having the glovebox closed normal?

    The schematic shows:

    1. When the switch terminals are closed = lights "on"

    2. When the switch terminals are open = lights "off"

    You'll need to then apply the mechanical logic of the mechanism+switch to that.

    They are abbreviations for:

    NC = Normally closed = when not actuated, the switch contacts are closed, and, when actuated, the switch contacts are open

    NO = Normally open = when not actuated, the switch contacts are open, and, when actuated, the switch contacts are closed

    They are terms that try to describe the logic of how different electric switches works, but the mechanism(s) used to actuate the switch can also invert the logic (for example, does a cam press a lever or release a lever) so it can get messed up/confusing as can the definition of "normal" -- for example, is a warm engine "normal", or is a cold engine "normal"?

    thank you steve for explaining those short cuts.

    here we have it different:
    if in normal position ( so not actuated ) it is closed and when actuated it is open then we say it is an opener ( oeffner )
    and if nomal it is open and when actuted it is closed then we call it an closer ( schliesser )
    if it is now a switch or a relais it does not matter.

    so good to know: other countries - other thinking and explaining. so good that we have this forum here to learn from each other :)
