Hi guys - I tried to do a search for this as my driver side express auto up seems to have deactivated by itself but didn't find much info. Does anyone have some quick instructions on how to re-program it? Much appreciated. Thanks!

I believe it may be more of a hardware(bad switch) than software problem

Thanks for the response. When I did a search some one had the same problem and others mentioned that they can re-program it. Not really sure but I have tried to hold the switch up for about a minute to see if that worked but didn't...

Do it again. Run it all the way down and hold the switch for 15 seconds and then run it all the way closed and hold it again for 15 seconds.

Do all four windows.

This is the same way the sunroof is reprogrammed.

thanks I just tried this but didn't work. I'll try it again but seems like it will be another trip to the dealer unless someone else has any other suggestions.

Does the one-touch feature not work either way? Do you feel the different pressure point at the button for the one-touch case?

idragen

it works going down, and it also works for up and down on all the other windows . I don't know if the pressure point feels different though

The same exact thing happened to my car, down would work, but up didn't. I just took it to the dealers and they finished the same day. Good Luck!

But you don't know how it was fixed or you don't want to share the info? Was it a broken switch that was replaced or still an issue with window motors normalisation.
