How do you fix slats on mini blinds that will not turn open or close?

To fix slats on mini blinds that won't turn open or close, first check for any obstructions or debris in the mechanism. Gently pull on the lift cord to ensure it’s not tangled. If the slats are still stuck, inspect the tilt mechanism at the top of the blinds for any damage or misalignment; you may need to realign or replace it. Lubricating the tilt mechanism with a silicone spray can also help restore smooth operation.
