Electric Window Stuck Down

    Hello,
    Need help with 93 Civic LX; left rear electric window will not raise
    using switch at either driver's door switch panel or rear left door switch.
    Have full access to rear door panel. Left rear door lock is operable so
    current is getting to the door panel; wires leading from door to center post
    do not appear frayed. 20 Amp fuse for electric window intact. Trying just
    to raise window to fully "up" position; if the window regulator is broken,
    is there a way to manually raise the widow to the "up" position? Any help
    with this would be appreciated. Haynes manual is not helping much.

    Sorry, I don't know the answer, :) but the guys over at the VW
    newsgroup might be able to help :) since it happens to VWs about 200x
    as often.

    If you don't find a quick answer here, you could undo two or three
    screws and wedge a piece of hockey stick (I'm not saying I hate hockey,
    use bagpipes instead) under the sucker temporarily. Put a dab of contact
    cenment on both ends of the stick or it will surely work itself loose
    half-way to wherever you're going in a blizzard. (Murphy's Law)

    I'm not sure if this is the case, but check out the driver side door
    switch. ALL other window switches connect to that one, so if that one's
    faulty, it does not matter if the other switches work. Because of the
    design of the switches in the older Hondas (at least in my 94 Accord and
    most likely in your 93 as well), whenever you activate the switch a
    small current arc forms, and it gradually burns the contact surface.
    This leads to corrosion and eventually the switch fails completely. The
    first indication is if the windows motors work a lot slower than usual
    (corrosion leads to higher resistence on the circuit), and then it just
    stopps working.

    On my car the driver's side window switch was completely corroded, and
    the others were well on their way as well. Honda wanted CAD$200 for a
    new one. I took it apart, cleaned all the contacts and it still works
    almost a year later. True, it was a real pain to get that switch apart
    and then back together again, but it was worth it.

    The door locks and the power windows get power through separate wires
    (they don't even share a ground lead) so the fact that the power locks
    work does not mean much.

    As you probably know, each window regulator has its own fuse. The fuse
    for left rear is #7.

    If you open up the rear door panel, try unplugging the wires to the
    motor and measure the voltage at the wires as you operate the switches
    (try both the one in the driver's door and the one in the left rear
    door). On "UP" you should see battery voltage with positive at the
    RED/YEL wire and negative at the RED/BLU wire. On "Down" you should get
    the opposite polarity.

    Measuring at the switch in the left rear door, there should be battery
    voltage at YEL/BLK (with respect to ground) any time the ignition is on.
    With the driver's door switch left alone there should be continuity to
    ground on both the YEL and the YEL/GRN at the switch in the left rear
    door.

    To check the motor apply battery voltage to the terminals at the motor.
    If nothing happens, reverse polarity and try again. If nothing happens
    either way, your motor probably has failed.

    Let me know if you want scans from the service manual.

    Cosmin, A buddy of mine turned me on to a device called a 'quench-arc',
    which is simply a high value resistor with a capacitor in parallel, in a
    package the size of a large resistor. Any time I overhaul anything with
    'sparky' contacts, I install quencharcs across the contacts. Clothes
    dryer timer, start winding switch on a washing machine, even the high
    beam flasher switch comes to mind too.

    Electronic stores sell them, but probably not Radio Shack: "You've got
    Questions, We've got Acne"

    Randolph's comments are very good but I would like to add a couple of
    comments:

    1. If you don't have a multimeter, buy one. Even an inexpensive one
    will work.

    2. I think Randolph is suggesting that if you get a length of speaker
    wire (two conductor), unplug the motor in the door. Stick one end of
    each wire in the plug to the motor, at the other end touch the wires
    to the battery and if nothing happens reverse the wires and try again.
    By doing this you have bypassed all the contol switches.

    3. Do grease all the moving parts on the window mechanism, use a white
    lithium grease. A couple of months ago I repaired a 92 Accord window
    by greasing it. It was a cheep fix.
