Hello, It could be that your window has shifted and the locking hooks on the window will not disengage with the operator. If so, I'm not sure that there is an easy fix. Check one of the windows that open normally to look over the side linkage and the locking hooks to see how they should operate. Also, try using a type of spray lubricant to help the windows operate more smoothly. I'm not sure how your windows were installed but you might be able to remove some of the installation screws and try to square up the main frame of the window. Take a look at the related video to assist you with the troubleshooting process. |
