The part that the sliding door handle latches into is cracked, as you can see in the picture, circled in green. I hope you can identify it from the picture. It looks like it should be easy to replace.
The other picture shows the two parts of a sliding window handle. The lower part, that my finger is touching, can keep the handle locked. But that lower part falls down. I think it used to have a spring that fell out. (I'm not the original owner so I don't know the history). Again, hoping you can identify the part and have a replacement! Additional info: HOA docs show that the brand name is Milgard.
Many thanks.
