    and the tailgate is another story. When the misses busted the tailgate window I just decided to replace it all.. glass, motor, window channel, and regulator. Now its slower than before and even gets stuck half way. And get this, when I roll the window down- one side of the tailgate door unlatches! I don't get it...

    well i have doors so i don't know what to say about the gate window. and it's getting cold your windows will start to slow down, that's just the way it is. /forums/images/graemlins/burb.gif

    Open up the tailgate and watch closely as the window goes up and down. It sounds like the window mechanism is getting hung on the door latching mechanism. You probably just need to bend something out of the way and then it won't hang or pop the latch open any more. /forums/images/graemlins/cool.gif

    Sounds like already did the stuff that should have made it move quicker, except check all the connections. There's a lot of wire and several connections between the battery and the tailgate. After more than 10 years it's a good bet there's some corrosion and loose connections somewhere along the current path. /forums/images/graemlins/frown.gif

    I had similar problem when I replaced my rear window last year. Do as Harry says and pay attention to the sliders the windows sides slide in. My also was hitting s bit on the inner side if the frame where the window comes out at. Good luck!!

    The current was my next thought. I was thinking of measuring the voltage to the motor. What should it be?

    All of the windows are kind of slow....does that mean the problem could be the relay or up in the fuse box area?

    are they all slow from your door or from each individual door.

    Voltage at any of the motors should be pretty close to battery voltage. I'll bet that you're gonna find something closer to 9 or 10 volts though. Since they're all slow, check a wiring diagram and see if you can find a common power feed for them all and start by cleaning up that connection.

    yeah..all of the windows are slow. The tailgate is the worst though because it has a mystery resistance too. I think Harry is right. I'll have to check the common feed..maybe its a relay???

    By the way, did this problem show up after you did anything? I mounted a fire extinguisher & hit a line I didn't know was there. Anyway, just a thought.

    No I haven't done anything for a long time. And I just noticed yesterday that my vent selector switch turns on the ac compresor when I slide it over to defrost... I doubt it is related...my sub just has demons

    The a/c is supposed to come on with the defroster. It helps remove moisture from the air, which clears the windows much better. /forums/images/graemlins/cool.gif

    burblover,
    I did the same thing. Let me guess right next to the drivers seat and the door. infront of the seat belt. /forums/images/graemlins/grin.gif
    The most common spot I have found actually runs to the main drivers switch. It is the main supply for the rest. I noticed on mine if I hold the drivers switch and the passanger of the ofending door pushes their's as well the window goes up much faster.
    I think they all have demons. /forums/images/graemlins/angryfire.gif

    the fringe of insanity (only on mondays)
    my 85 had the same problem with the windows (has rear doors so i dont know about that)
    i pulled the door panels off and checked the cranks and the arms and all connecting points and the original grease on them was mostly gone and pretty hardened.i cleaned that off and hit them with some white lithium grease then cleaned all the terminals and dielectic greased all the connections.they do work faster now but not as quick as new.
    as far as the rear window id say look for something in the door its getting hung up on too,or even if the doors not quite aligned right and getting stuck.
    goodluck

    I thought that might be the case but wasn't sure. Thanks Harry, you saved me from haggling with it..

    I think Im just going to have to roll over on this one and accept that it will never work properly. New motor, regulator, key switch, and I adjusted the felt channels. Then only other option I can think of is getting an entire junkyard tailgate..but that probably means painting it and there is still no guarantee that it will work properly. boo hoo. I still haven't checked the voltage though so that may yield and explantion. Is there a relay for the windows on 89's?

    Ha! You wanna talk about demons? Couple years ago the family &I was going thru Wildlife Safari in Oregon. Everything was fine until the 1st lions area. Ther's a huge 20' fence and gate to drive through with large signs stating "Your windows must be up" for obvious reasons. Since everybody's window was down, we proceeded to roll them up and FIITTZZZ was all she wrote! So I pulled over to look under the dash when the gaurd in the tower "kindly" blared over the loudspeaker to get back in the car. yelled back my dilemma and the gaurd ordered up an escort vehicle to assist us. Meanwhile, there's at least 15 cars waiting behind us. You wanna talk about feeling stupid! Well, apperently te previuos owner wired all the windows to a fuse instead of the original breaker. Why? my guess is the breaker failed, he didn't know what it was, and proceeded to "fix" te problem Gomer style /forums/images/graemlins/blush.gif /forums/images/graemlins/rolleyes.gif

    you say you replaced the window channel. the one that the window glues into.. did you replace the tracks that the glass slides in? did you unbolt or move them at all? the tracks have some adjustment on them and they may be too tight against the glass. also did you lube the new regulator with anything? it sould have had some lithium lube on it from the factory but sometimes the skimp a little. try adjusting the tracks or they may be bent or rusty. spray the regulator with lithum lube and spray the tracks with some silicone spray.
    wal-mart sell's some silicone by prestone that works great for $.99. as far as your door windows (it's a chevy they are all slow) pull your door panels and clean the regulator with some cleaner and then relube them with lithium lube. also lube the rollers where they go into the channel. then take that silicone spray and soak the crap out of all the felts on all of the doors and they should speed up some.

    l8ter, Derek

    I did not replace the tray that the window bottom glues into; no reason to. I did take out the felt channels and re-adjust them. I also bent them open a bit more in a few places. What else..new regulator, key switch (2nd), motor, and outer felt swipe. And everything is lubed up pretty well.

    Now things are pretty well straightened out. Its not fast but it is working. Recently I cracked the back window an inch or so just to let some air in. I noticed that one side was about 1/2 an inch lower than the other. I took it apart for the 10th time and sure enough the guy that installed it hadn't aligned those two little lines on the regulator. I made the adjustment and it is working decently.

    I havent put silicone on the door felt yet though. I have been reluctant to do so because I don't want ot get grime all over my sleeve every time I open the window...

    Im also convinced there is a bit of an electrical issue too. When the rpms are up the windows move way faster. I still want to see how many volts the window motors are getting.
