Windshield locked in place

Heya fellas. I have a 2000 LT. The windshield was working fine, up and down, no problems. It was in the fully upward position on the freeway, I slowed down to 20-30 mph and it wouldn't go back down. Is it somehow locked in place as a safety mechanism? When I press the button all I hear is one click like the motor is trying to engage the windshield but nothing happens. Is there a way to unlock this to work properly? I tried turning the bike on and off, and tuggin the windshield gently, but nothing helped. Any help would be much appreciated, thanks.

Re: Windshield locked in place

There is no lock mechanism. The pivots may be binding or the motor gear box is jammed up. There are relays and limit switches as well that could be malfunctioning.

Re: Windshield locked in place

check the fuses. On my 09 lt there are two servos for windscreen movement. One up and one down...thus two fuses. They should be documented in your owners manual...good luck

Re: Windshield locked in place

There are two fuses one unswitched power and one switched power F7 and F1, both 15 amp.

The switched power goes to the control switch and gets routed to the respective relay (up or down). The limit switches cut the operating relay off when the end of travel is detected. The unswitched fuse feeds both relays.

One motor, two relays and two limit switches. Could be any of them.

Re: Windshield locked in place

I had the same issue a few years back. It was fine going up and down and then all of the sudden it was stuck about mid way. I could continue to go up but not down. It was one of the relays. Corrosion is a wonderful thing to chase down. If it is like my issue, just re-seat all your relays and fuses. Chances are it is just corroded.

Re: Windshield locked in place

Thanks for all the help, fellas. I checked the fuses and all is good there. I would check the relays, but I don't know what I'm looking for. Does anyone know where these windshield relays are? Thanks in advance...

Re: Windshield locked in place

Be sure all of the pivot points are well lubed. There are lots of them and I try to remember each one at every oil change.

Remove the windshield then remove the plastic cover under it. There is one hidden screw behind the dash map light. The relays are on the windshield mechanism rack assembly under that cover.

Re: Windshield locked in place

If you need the motor, PM me, got one I'll part with. Arms are broken but the motor and drive is good.

Re: Windshield locked in place

Thanks for all the help, and thanks Gunny for the offer on the motor, but it looks like the motor is ok. So I took it apart and found the two relays right in the front under the windshield. I knew it was them because I hit the down button on the handle bar while I touched it. It looks like the previous owner had this trouble before. I took the relays out and shot them with some compressed air and reinstalled them. I tried the up/down button again, and it worked! I moved it up, then down, then up again, and it got stuck at the top again. So I pulled the Bosch relay, reinstalled it again, and it started working again. Weird. So I figured if it has locked up twice, it will happen again. So there I sat, moving my windshield up and down 40 times. It didn't do it again, so I put the bike back together fully prepared to take it apart again someday soon. I'm taking a 1000 mile trip next month, and the last thing I want is this thing to get stuck in the down position!

My question is this. Are these two relays supposed to be identical? One is a Tyco, and one is a Bosch. The Bosch is the one on the right, and it doesn't look like it belongs there because it doesn't have the little clip deals that lock it down in place. Anyone recall what these should be? I wonder what the repair manual calls for... Here's some pics of the relays.

Re: Windshield locked in place

The manual does not call out a specific relay by PN but the parts catalog will have the BMW PN. Take one down to your local auto parts dealer and match it up with a new one. A relay is relay...

Re: Windshield locked in place

Haven't had any issues with sticking on my 07, I have lubed pivots twice. If it were to stick I'd much rather it be in the down position regardless of season or weather. I don't like looking through it. Good luck and ride safe.

Re: Windshield locked in place

I'd pull those relays again and put some dielectric grease on the contacts. It sure sounds to me like it's a contact issue given that you can remove/replace the relay and get it working again.

Re: Windshield locked in place

Hi Everyone,

Seems like I've been having a similar issue with my windshield. The windshield will move 3/4 of the way up and stop. Going down of course, it does its job. Reading through the thread, I had noticed that Jzeiler mentioned that there was an upper/lower limit switch. This could be my culprit. Can anyone tell me where the upper limit switch is located? Yes I still feel like a 'nube' here.
Could this also be a faulty relay if it's always stopping in the same place? I know that I can change out the relays...that's fairly simple to do.

Thanks for all your help folks!

Cheers and all the best in the riding season! Mine is about to begin...

Re: Windshield locked in place

Remove the windshield, then the plastic panel just under the windshield (there is a hidden screw behind the map light for the dash). You will see the entire mechanism then with relays and limit switches.
