7 Reasons You Need to Fix Cordless Top Down Bottom Up Blinds
- Blinds are difficult to raise or lower – the most possible reason could be due to issues with the cordless mechanism.
- Concealed tension-generating cables or ladder strings get broken – resultantly, your cordless blinds will cease to operate and require urgent restringing.
- Blinds get crooked or uneven – the slats won’t fit tightly into each other when closed, allowing harsh sun, cold drafts, and hot wind seep through.
- Springs get ‘deactivated’ – to ‘reactivate’ the springs, lower the blind to as far as it will go.
- Tension springs are broken – welding may not work, the only better solution is replacing them with new, fresh springs.
- Top, bottom, floating rails need fixing – if any of these rails is malfunctioning, the cordless mechanism won’t work accurately.
- Mounting brackets are loose or misaligned – realigning the brackets at exact 180-degree and rescrewing them tightly could be a viable option.
Dos & Don’ts of Fixing Cordless Top Bottom Blinds in Your RV
Dos
- If the cordless mechanism needs fixing, unmount the blinds from the headrail and lay them on a flat, clean surface when fixing the cordless mechanism.
- Do wear safety gear, such as safety goggles (to protect your eyes from dirt or lubricants), work gloves (to save your hands from cuts, scrapes, and splinters), and a sturdy step ladder (if shades on the RV windows are hard to reach).
- Make sure the internal cords are not bundled up together, as it may mechanically stop the top or bottom part from raising, lowering or positioning.
- Uninstall (when removing shades) and reinstall cord safety devices (when remounting the shades).
Don’ts
- When repairing, don’t pull the strings so hard that it gets broken or damages the fragile weave.
- If your top down bottom up shades are motorized, keep water droplets or sprinkles from the electric components when fixing them.
- Avoid using wrong lubricants – we recommend a dry, silicone-based spray to reduce friction without attracting dirt and grime.
- Never ignore manufacturer’s guidelines when working on your RV’s top down blinds.
- Don’t nail your top or bottom part to the RV wall to eliminate light gaps, as it will inhibit their operation. Instead consider reducing the horizontal height of brackets, so that the fabric slides up or down while almost touching the RV walls or window frame (if mounted inside the recess).
Precautions When Repairing Cordless Top Down, Bottom Up Blinds in Your RV
- When working on motorized top down blinds or shades, turn off power or unplug the shoe to prevent electric shock.
- When using instant-dry glue to join broken cords, make sure it doesn’t spill over the fabric, as it will cause a permanent, irremovable stain.
- To prevent injuries to your little ones, keep them away from the work area in your motorhome.
- When tugging the shades to restore their function, don’t apply excessive force, lest they should get torn apart.
6 Quick, Effective DIY Fixes for Cordless Top Down Bottom Up Blinds in Your RV

Expert Tip
Harrison, one of your RV window treatment installation and repairing experts, recommends using superglue to join broken ends of a blind, instead of a threadlocker. The latter may add to the thickness of the blind and interfere with the smooth raising and lowering of the fabric.
