Most of the time the reason the window does not stay up is because one or more of the balance shoes have come off the pivot bar in the window. THIS IS NOT A DAMAGED WINDOW. Watch this video to see how easy it is to fix this issue.
TOOLS REQUIRED: Flat head screw driver.
Read on for step by step instructions.
Take the flat head screw driver and insert it into the metal part that has a “U” shape grove in it. The “U” is the locked position of the shoe (Shown in Figure 1)
Keeping a strong and steady hand, turn the screw driver clock wise until the “U” is now “C” shape (Open position). Shown in the figure 2 to the right.
IMPORTANT: The shoe is spring loaded to go upwards, please make sure you put downward pressure so that the shoes does spring upward.
Tap on the window near the shoe so that it sits inside the shoe.STEP 7:
Return the sash to its closed position

Please do not remove sash unless in an emergency. Just tilt sash for regular cleaning purposes.
