First, I would check and make sure the cam is positioned properly. The cam is oval rather than round and a common problem homeowners have is closing the window without the pivot pin securely in the cam. If this is the problem, all you need is a large flathead screwdriver to insert into the cam and twist it counter-clockwise.

If that's not the problem, I would just contact a local Simonto distributor who can be found by using the "dealer locator" on Simonton's website. Simonton has used the same "Denny Clip" on all their double-hung windows since 1980 so any Simonton dealer should be able to provide you with one.

I would also press Sears to fix it as I believe their warranty covers this type of repair. You will need to find you local Sears contractor. Don't try and get it fixed through a Sears retail store.

hello again & thank you so much for the help - i really do not know if the cam is the right part - i have a broken piece laying in the inside sill that i could post a pic of to make sure - it sounds like the denny clip is what i want - it has been a b____ trying to get some help & so glad this forum exists w/ such good people on board - i dread dealing w/ sears though - once again i thank you
