Duct tape fixes a lot of sins (?)
Wedge a piece of something grippy in the window car sill (?)
I have a car window that likes to slip down. Is there a product or trick I could use to keep it from sliding down til I can get it fixed?
Sounds like the window regulator is broke and needs to replaced yin .for temporary fix pull all the way up and duct tape it to car door frame
Once you have it in position, you might be able to secure it with a little wedge of sponge. (I suspect it will drive you nuts until you get it properly repaired.) xoxo
