Replace the Rubber Seal

• 1). Access your sun roof from inside your vehicle by taking down the trim work and the headliner that cover the sun roof's mechanics.
  
  
• 2). Remove the screws and bolts that hold the sun roof to the body of your Honda CR-V. Disconnect the power source from the rear of your sun roof.
  
  
• 3). Lift the sun roof up and away from the vehicle. Ask for help so you don't damage the sun roof or the vehicle during this process.
  
  
• 4). Pull out the old rubber seal from its trench. Use your plastic scraper tool to take off any remaining rubber or adhesive. Look in the trench for signs of rust; if you see such signs, paint the trench with Rustoleum to protect the vehicle.
  
  
• 5). Lay the new rubber seal into the trench, starting with the outer lip and working toward the inner lip. Look for bulges or wrinkles. If you find any, remove the seal and reinstall it until you have a smooth, even surface.
  
  
• 6). Place the sun roof back into it's original position and secure it using the screws and bolts you removed earlier. Stop often to check for level. Plug the power source back in.
  
  
• 7). Return the headliner and the interior trim to their original positions inside the vehicle.
  
  

Maintain Your Sun Roof

• 1). Park your Honda CR-V on a level surface and look at the sun roof. Make sure it's seated properly, not lifted or raised at one side or corner. If you see such warping, it's an indication the tracks need cleaning, or that the rubber seal needs to be replaced.
  
  
• 2). Clean the rubber seal around the exterior of your sun roof with damp, lint-free cloth. Look for cracks, gaps or excessive wear in the seal. Replace it if you find such defects, to prevent leaking in the interior of your Honda CR-V.
  
  
• 3). Remove the interior trim and allow the cloth that covers the ceiling of your Honda CR-V to drop down so you can access the tracks to your sun roof. Use compressed air to blow out debris and treat the tracks with 3-In-One Lubricant.
  
  
• 4). Locate the four drain tubes that remove excess water from your sun roof. Use compressed air to blow any debris or clogs. Two of these tubes drain to the front of your vehicle and two drain to the rear, usually behind the tail lights. Check your owner's manual for exact locations, as they can vary slightly.
