If the dash cam keeps falling off the windshield, you can use 3M adhesive and a bonding promoter to secure it firmly. Before installing the dash cam, ensure the installation area on the windshield is clean. For dash cams fixed with adhesive tape, make sure the surface is dry—using a hairdryer to heat the adhesive tape can improve adhesion. For suction cup-mounted dash cams, applying a small amount of water to the suction cup before attaching it to the windshield can enhance stability. Before installation, determine the optimal position for the dash cam. It is recommended to install it in the center or slightly to the right of the rearview mirror for an optimal recording angle, which provides more convincing evidence. Many dash cams are designed in a rearview mirror style, allowing direct replacement of the original rearview mirror.

I've been driving for decades and often encounter the issue of dash cams falling off, especially in summer when the car interior gets hot. If there's too much dust on the windshield, the adhesive won't stick properly. Dust is the main culprit—before installation, I always thoroughly clean the glass with alcohol or detergent to ensure the surface is dry and free of moisture. I've found that wiping it a few times with a microfiber cloth before sticking the cam makes it much more secure. Aging adhesive pads also affect stickiness; if your dash cam has been in use for nearly a year, remember to check if the pad is cracked and replace it if necessary. Temperature fluctuations can soften the adhesive, so try to park in shaded areas to avoid direct sunlight, which helps extend its lifespan. From a cost perspective, spending a few dollars on strong double-sided tape is more economical than frequently replacing the device. Safe driving comes first, and having it fall off constantly is truly annoying.

I've done quite a few minor car modifications and found that dashcams often don't stay firmly attached due to glue type or installation issues. While 3M tape is good, it tends to fail over time. I recommend using removable adhesive or magnetic mounts, which can be bought online for just over ten bucks. When installing, don't rush—press evenly to ensure the adhesive fully bonds, and avoid driving on bumpy roads right after installation. I've also tried adding a layer of adhesive-enhancing spray or cleaning with alcohol and waiting a few minutes before securing it. When choosing products, look for models with good temperature resistance—many brands now perform well and are less likely to fall off. For DIY reinforcement, a dab of hot glue at the edges can serve as a simple fix. Sharing this experience to help everyone save trouble and stay safe.

How to Start as a Used Car Broker for Beginners?

You need to be able to identify whether it's an accident-involved vehicle, as such cars are tricky in the current market—handling them poorly could lead to losses. At the very least, you should be able to inspect the car's condition by looking, smelling, and listening. Sellers will naturally first inquire about the price of their car from the broker. At this point, the broker should absolutely avoid rushing to lower the price.

How to Drive on a Highway with Only 2 Lanes?

Before entering the highway, the car owner must go to a repair shop or 4S store to check whether the vehicle's condition is normal and whether the tire pressure is normal. The speed should not be too fast, but also not too slow, because there are maximum and minimum speed limits on the highway, and you cannot change lanes back and forth. You cannot always drive on the left side, because the left lane is for overtaking and cannot be used continuously; it should only be used when overtaking.

Where is the Altima air-fuel ratio sensor 1b1 located?

The Altima air-fuel ratio sensor 1b1 is located above the three-way catalytic converter, with the V6 engine B1 air-fuel ratio sensor positioned on the left side. Since the three-way catalyst's purification capacity for CO, HC, and NOx drops sharply once the air-fuel ratio of the mixture deviates from the theoretical value, an oxygen sensor is installed in the exhaust pipe to detect the oxygen concentration in the exhaust. It then sends feedback signals to the ECU, which in turn adjusts the fuel injection volume from the injectors, thereby maintaining the air-fuel ratio of the mixture near the theoretical value.
