    Man it seems that I fix one thing and something else goes wrong. I just rebuilt the carbs and over the 2 months I spent rebuilding and adjusting the carbs the car sat in my garge with the windows down. I haven't touched them. Took the car out for a test drive today and tried to put the windows up...no way. Checked the fuses and they are OK. Tried to find the thread that was on here a couple months ago on the same problem (I think) but no luck. Any ideas or advise as to why my windows got sick? The windows worked fine before and I was pleased because they worked pretty fast. Woe is me.

    Is your battery fully charged? Check the fuses and relays. Then check the contacts. Check the contacts at the window switch too, as they do corrode. make sure your switches are wired properly.
    Or did you mean that your windows are slow?
    the fix for that resides here:

    LOL! I paid a shop to fix mine and paint the car...

    By the time I got around to picking it up, it was stuck 'up', I paid them and thanked him for his efforts, a long time trusted friend....

    He was crestfallen they were not working, you could just see it on his face as I drove off!

    He had worked the motor a long time with the manual crank to free it up......try spraying some polylube into it, but really a teardown to regrease is the best way.......


    Opening the door now for air....in Texas. Wintertime soon anyway...no worries.

    He'd gone to all the trouble to translate the Italian colors in the wiring diagram, after all....ROTFLMAO!

    Thanks guys. Located the relays on the owners manual so I'll check them tomorrow. How can I tell if they are good or not and where do you get new ones if they are bad. If this is the problem why did they go bad and what might I have done to cause this...don't want to do it again. To answer some of the above questions....the battery has a full charge, and they are not slow they just don't do anything. Worked fine two months ago and I haven't touched them.

    Hi Doc,

    Switch your window relays with other relays on the board that you know to be good.

    The relays used are an industry standard, the Boshe relay in my GMC Jimmy is exactly the same as the ones in my 308. Double check the voltage and amperage requirements before using, just to be on the safe side. You can get new ones at most auto parts stores.

    In addition to worn and dirty contacts in my switches I found a loose motor ground in my passenger door that killed that window completely.

    I changed all of my switches, cleaned and tightened all of the connectors and the windows race up and down now.

    Spasso you're a peach. I'll check it out this weekend. I wonder though why did both windows go out at the same time without any use? It's like there is some central point that effects both windows. Does one circut rely on the other for power? Oh well there is no sense to speculate...just start checking things out like you suggested. Thanks.

    This could be a lot simpler than all of that.
    The same thing happened to me when I worked on my car this summer. If I recall correctly, if the window switch isn't connected on one door, it also stops the other door's window from operating. Are both switches hooked up? Sounds just like what happened to me.

    One thing I learned while trouble shooting my windows is all of the switches should be hot (with the key on), even when all switches are in neutral. The primary function of each switch is to "shunt' the power one of two ways to motor making it run forward or backwards.

    This is the thread from last winter when I did mine.

    Guys
    I went out today to work on my windows armed with all the great info above. I first checked the fuse box (I replaced with NAPA boxes and glass fuses months ago). I saw that the two 25 amp fuses for the two windows were OK but checked the continunity of the fuses anyway. I also noticed that the first fuse in the box for the wipers,turn signial, and stop relay was blown. This is a 16 amp fuse. When I replaced it the wipers started to work. Then I thought could it be possible???? Sure enough I tried the windows and they work fine. Of course I'm happy the windows are working but I hate that I don't know why. You will probably think I screwed up the wiring when I rebuilt the fuse box but I marked every wire and took many pictures. I'm confident I didn't mess anything up. So I'll bow to your expertise and let you figure it out. I'm just glad my windows work for now. May be there is a good explanation for what happened. Thanks for all of your suggestions.

    OK, now that I'm done with the funny noise freakout, gonna try to attack these windows whose operation is so random as to suggest that the sole operating factor is whether the ghost of Mr. Marelli feels like pushing them up or down at any particular time: My goal is to try to troubleshoot stuff that doesn't require pulling door panels first. So as I read this thread, I should go in this order(?):

    1. Fuses
    2. Fuse block connectors
    3. Relay (It's just 1 for the whole shebang, right?)
    4. Multi-pin connector thingy
    5. Switches

    Am I missin' sump'n?
    Cheers,
    Alex
