Tips for fixing blinds include identifying the type of blind that you are trying to repair, learning about the common problems encountered by the particular blind and checking the mechanical components of the blind for defects or damage. Fixing blinds usually entails simple troubleshooting techniques.
For blind slats that don't lower, check if the cord lock is faulty. If the cord lock is the problem, take the blind out of the window, and look for a pin in the cord-lock mechanism located in the headrail. Using a flat-head screwdriver, push the pin to disengage the cords and lower the blinds.
If blinds don't tilt, the tilt mechanism in the headrail tends to move while the slats remain stationary when the tilt rod is disconnected. To address this, find the tilt mechanism, and carefully push the end of the tilt rod back into place. If this doesn't work, then the tilt mechanism may need replacing.
