balance springs need repair

House was built in 1988, came with French non-tilting windows. A couple windows have balance springs (not workinig) that are fully extended (see picture)--of course this does not allow the window to say open without help of a two-by-four underneath it.

Looking where the take-out clips are normally located, are plastic strips. I've attached a picture of one broken, and one (I believe not broken) plastic strip. All the windows throughoout the house are the same.

I need to remove the bottom window to access (and maybe replace if necessary) the balance springs but (1) have no instructions of how to remove the window from the frame, (2) if take-out clips are actually necessary to get the window out, and (3) what parts I need to identify for a fix. Can you help?

Thank you in advance.

Thanks for getting back with me. I though the same (similar to 16-203) bit instead found that these are simply plastic covers--and I cannot figure out what their purpose really is. I have 20 windows with the same plastic covers throughout the house and non of they pop out (forward) as a take-out clip for the sash. If an attempt is made to pop these out they simply break/bridle (as to why I sent the second picture with only half of a cover). Do you think this is only a cover for me to remove and install a take-out clip when necessary (have you seen this before?)?

Hope to hear from you back again, soon..... Rick

You know, I used the screw suggestion you mentioned earlier and that seemed to work. Meanwhile, I will have to look for replacement clips as the old ones are all dry rotten. They look like the 16-203 but without the two-9/32" lips. Do you have any of these (without the lips?)?
