[support] reinstall a module?

Hi,

I'm having a problem with a module that was working before. It's with the location module and there's an sql error suddenly. As far as I know nothing was changed. I was thinking that a good first start would be to reinstall the module and see if that fixes it, since the module worked in the beginning. Is there a way for me to do that without deleting the data that's already been mentioned? Can I just trigger the install function in some way? If I disable and/or delete the module will it delete the relevant data already entered? Pardon me if this is something that's different per module, I'm hoping there's a standard answer, or that someone has specific experience with this module and this problem.
