It is Camry LE 1994. The motorized antenna doesn't go down all the way when I turn off the engine. How can I replace it?
I had the same problem with my first car, similar to yours.
The motorized antenna has little plastic teeth that allow it to move up and down and the plastic teeth near the top was worn down so it would always stick up a couple inches.
Sounds like a similar issue so you might want to check that. I had to replace the antenna and if I recall it wasn't too expensive.
