If the sunroof is not opened, the possibility of clogging is very small. Procedure for replacing window glass: Disconnect the cable from the negative terminal of the . Locate and remove the hidden bolts, remove the latch, and take off the door trim panel; adjust the window, remove the glass fixing bolts, take out the glass, and finally install it. Installation precautions: Before installation, lay protective pads to protect vulnerable areas and seats. Use protective tape on the adjacent frame parts of the bonding area before activating the coating adhesion. Use professional cleaners to treat unconventional contamination in the bonding area to ensure no air or water leakage. Apply an activator to the bonding area and activate the original black primer to make the glass bonding more secure.

I've been driving for over twenty years, and one of my cars had a sunroof that I almost never opened. I thought it wasn't a big deal until one time after heavy rain, I found the car's carpet completely soaked. Upon inspection, I discovered the drainage holes were completely blocked by a pile of leaves and small insects. The mechanic told me that while the sunroof's sealing strip normally keeps rain out, if the drainage holes aren't used for a long time, dust and debris gradually accumulate and clog the pipes. When rainwater seeps in and can't drain away, it backs up into the car. Since then, I've learned to check the drainage holes every few months and clean out any debris. Actually, whether the sunroof is opened or not doesn't directly affect the clogging, but neglecting allows dirt to pile up more and more, potentially damaging electronic components when dealing with it later.

When performing car , pay attention to the sunroof drainage system. I've seen many cases where leaks occur because owners rarely open their sunroof. The drainage holes are located in the corners. If not cleaned, dust, leaves, or even small insects can clog them, preventing rainwater from draining properly and causing leaks into the cabin. It's recommended to check the drainage channels during each car wash by pouring some water to test the flow or using a thin wire to clear the pipes. This way, even if you rarely use the sunroof, you can prevent clogging issues. Otherwise, dealing with mold inside the car can be costly and not worth the trouble.

If the sunroof is not used for a long time, the drainage holes can indeed become clogged, mainly due to the accumulation of dust and small debris near the sealing strips. A while ago, I parked under a tree, and fallen leaves got inside and blocked the drainage pipe, causing water leakage when it rained and soaking the back seat. After cleaning, the problem was resolved. Since then, I've been more careful about doing simple regular , which doesn't require much effort but helps avoid major damage.

When the sunroof drain holes are clogged, rainwater can leak into the car, wetting the interior and potentially corroding parts. Once, my car had this issue due to lack of , and the clogged drainage system was quite troublesome to repair. It's advisable to regularly clean the debris from the drainage channels when parking in dusty or leafy areas to keep them clear. This way, even if you don't use the sunroof, you can protect your car and reduce safety risks.

In areas with frequent rainy seasons, sunroofs can develop issues even when not in use. When I park in the south, bird droppings and pollen often clog the drainage holes, causing water leakage during rain. The solution is to regularly open the cover for cleaning to keep the pipes clear. With proper like this, you won't have to worry about clogging even if the sunroof remains closed for long periods, preventing more serious problems.
