New Member Window wont open

[Anthony]

I just purchased a 2006 Sunline T-276 SR Classic. It has 3 vertical slider windows and I can't get any of them to open. Didn't get a owner's manual with trailer !

The vertical windows have two spring loaded latches, on the left and right of the top of the lower window pane. They slide in toward the center of the window to release. You have to hold them in and wiggle the window and lift. The pane often gets stuck if not moved for a while. The latches then spring back out into a couple holes along the way up to hold it open.

To add to what BenB stated, the single hung, up and down lifting windows, in your camper that is the 2 in the bedroom and the 1, bath window, dirt gets stuck in the slide tracks if the window has not been opened in a while.

To unstick, a stuck up and down window, lift the bottom screen up, way up, it slides up, and spray liquid silicone spray in the channel the window slides in. Do the bottom and sides of the channel up to the lifted screen.

Then so as Ben said, pull the 2 plunger levers towards the center and, yank the window up. Sometimes pushing down and then up constantly helps giggle it loose.

If you want to take the screen out, it is spring loaded on one side. Slide the screen up about 2" to 3" so the curved bottom corners come up out of the bottom track. Then push the screen frame to the side, one side is rigid, the other is spring loaded. The rigid side will not move at all, the spring side will allow the screen to compress and you can pull out the rigid side from the track.

Taking the screen out helps sometimes on real stuck windows to get the silicone spray into the channels better.

Hope this helps
