Neither of my windows will roll up after removing the ignition lock barrel and rotating 180 degrees (switch would not return to position 0) - windows worked fine before (only other thing I did was disconnect battery). Prior to this I had the steering assy out to upgrade (had ignition switch problem) so the lock barrel has been out a few times in the past week or so and windows always worked fine till now.

Checked D1 fuse and it was fine. Is there any other fuse I need to check?

Any other suggestions?

Thanks,

Bill

It's your battery disconect. There is a trick of holding the widow swithces down (with ignition on) for 15 seconds (somthing like that). Do a search for the exact nethod and all you woes will evaporate.

Is this what you mean:

When you disconnect the battery, the windows have to re-learn their upper and lower travel limits. This is done by "teaching" the windows: pressing and holding the window switches until the windows are completely up or down and then vice versa. It's in the owner's manual somewhere.

Before I made this post I pushed the switches the normal way you would and got no movement in either Up/Down direction - thought I could hear a little noise from them - so do I just need to hold them down longer? Since the windows are in the down position which direction should I go with first?

Thanks.

I don't think that the order in which you do the re-learn matters.

Start with the Up direction and hold it for five to ten seconds after it reaches the completely closed position, then repeat for the other direction.

Last question - should this be done with the doors open or closed?

Will give this a shot tonight.

Thanks.

Got home and gave it a shot with no success - dropped the top and bingo it worked..

Found reference to this procedure in the Bentley shop manual ( all 3 sentences) and it says that the top must be closed for this procedure - is this a typo or when they say closed don they mean in the stored position? Confusing.

Anyway everything is fine now - thanks to everyone for all the help.
