Borgward BX7 sunroof drainage holes are located in the A-pillar. The position of the sunroof drainage outlets may vary depending on the vehicle model. Generally, sunroof drainage holes are positioned in the A-pillar and C-pillar areas of the car. Additionally, vehicles have other drainage holes, including the air conditioning drainage hole, engine compartment drainage hole, door drainage hole, fuel tank drainage hole, and exhaust pipe drainage hole. Below is an introduction to these drainage holes: 1. Air conditioning drainage hole: Typically located under the passenger side on the vehicle chassis, it uses a hose to drain condensation water from the air conditioning system. 2. Engine compartment drainage hole: Positioned on both sides of the windshield wipers in the engine compartment, it channels rainwater out through the drainage channels on either side.

I've been driving my Borgward BX7 for a while now, and the sunroof drainage holes are quite crucial. They're located at the four corners of the sunroof rails—you can find two at the front and two at the back. These small holes aren't usually noticeable, but once they get clogged, big problems arise—rainwater can't drain properly and ends up flowing into the car, soaking the carpets and potentially damaging electronic components. Before the last rainy season, I made sure to inspect them by opening the sunroof and using a flashlight to check for leaves or mud in the holes. For cleaning, I gently poked through them with a bicycle brake cable—just be careful not to apply too much force and puncture the tubes. I recommend checking and clearing them every few months as a habit—it can save you a lot on repair costs. Also, try to avoid parking under trees, as fallen leaves can easily clog the holes and lead to leaks. Safe driving shouldn’t overlook these small details.

Locating the drainage holes on the Borgward BX7 sunroof is quite simple—they're positioned at the four corners along the sunroof edges. As someone who frequently performs DIY maintenance, I find the process straightforward: First, open the sunroof and inspect the small holes at both ends of the sliding tracks. These connect to thin tubes that channel water outside the vehicle. If clogged, I use a compressed air gun to blow through them or pour warm water to test the flow; smooth water drainage indicates they're clear, while blockage requires debris removal. Avoid using hard wires to poke, as they might damage the tubes. Common causes of clogs I've observed include dust accumulation or insect nests, especially during rainy springs. Regular checks can prevent interior leaks and carpet damage—trying it yourself saves a trip to the repair shop.

The drainage holes for the sunroof of the Borgward BX7 are located at the four corners of the sunroof to prevent rainwater from flowing inside and causing risks. As a safety-conscious person, I know that if these holes get blocked, water can accumulate on the headliner during heavy rain, seeping into the cabin, soaking the floor mats, or causing electrical shorts, which can be dangerous while driving. The holes are not positioned high, so you can check them yourself: open the sunroof, and the holes are at the junction points of the tracks. For regular maintenance, gently brush the exterior with a toothbrush or pour some water to confirm quick drainage. Developing a habit, such as cleaning them every season, can significantly reduce the probability of malfunctions. Safety is no small matter—these small checks ensure peace of mind.
