Mercedes E320 windows

Hey guys today I installed a pager alarm with roll up/down windows into a 1997 MB E320. I used a timer to extend the car's lock wire to roll the windows up. The cars unlock wire I connected to both the alarms unlock as well as channel-2 in order to roll down when the button is held. Now the windows roll up beautifully, however when I try to roll the windows down with the remote all the car does is unlock and that's it, the only time I can roll down the windows with the remote is if I lock and right away unlock and roll them down...This pissed me off because I spent a lot of time today trying different things with no luck, it seems I have bad luck with those particular cars because a while back I had another window problem with the same kind of car although that turned out to be some water in the switches (damn car washes)...anyway if you guys could suggest something I would really appreciate it.
