What to Do If the Dash Cam Won't Stick?

You can use 3M adhesive and bonding promoter to secure the dash cam firmly. Below is a guide on installing a dash cam: Clean the installation area: Before installing the dash cam, ensure the windshield installation area is thoroughly cleaned. Dry the adhesive: If the dash cam uses adhesive tape for fixation, the installation area must be free of moisture. You can use a hairdryer to warm the adhesive tape, which enhances adhesion and ensures a firmer hold. Apply water to the suction cup: For suction cup-mounted dash cams, lightly moisten the suction cup before attaching it to the windshield. This improves suction and provides a more stable hold. Choose the installation location: Before installing the dash cam, determine the optimal position. Ideally, install it in the center or slightly to the right of the rearview mirror for a proper filming angle. This ensures the footage is more convincing as evidence. Many dash cams are designed in a rearview mirror style, allowing you to replace the original rearview mirror with the dash cam directly.
I also encountered adhesion issues when installing my dash cam before, and it took me quite a while to figure out why. The oily film on the windshield surface is actually the main culprit, especially on new cars or recently tinted glass—it feels slippery to the touch. You need to repeatedly wipe the area where you plan to stick the mount with alcohol pads until the pads no longer turn yellow. Remember, never use water to clean it, as water leaves stains when dried, making adhesion even worse. If alcohol alone doesn’t work, try using a hairdryer on the glass for about 30 seconds to warm up the adhesive before pressing it firmly—this will double its stickiness. If it still falls off after trying these methods, consider switching to a static sticker, which adheres via static electricity without damaging the glass, or opt for a suction cup mount instead. If all else fails, a seasoned auto shop technician can get it securely attached in just 30 seconds.
