Reasons for Small Dots Appearing After Window Tint Installation

Reasons for small dots appearing after window tint installation include material issues and installation problems. Below are the detailed explanations: 1. Material Issues: Some low-quality automotive window films use industrial materials to reduce costs and lower prices, which can release gases such as benzene, formaldehyde, and TVOC. Since the film is applied to the inner surface of the car glass, these gases evaporate outward, causing bubbles. When a certain number of bubbles accumulate, they become visible on the outer surface, appearing as bubbles on the film. 2. Installation Problems: "Three parts film, seven parts installation." The quality of the installation significantly impacts the lifespan of the window film. If the technician lacks sufficient skill and fails to completely remove water during the processes of applying the film, smoothing it out, and drying the edges, moisture can remain. When the defogger line heats up, this moisture turns into gas, forming bubbles.

Why does the BMW 325 air conditioning pump clutch keep failing?

There are many reasons why the BMW 325 air conditioning pump clutch keeps failing, such as poor contact causing the electromagnetic clutch of the car air conditioning compressor to burn out.

Incorrect gap between mounting surfaces: There should be a certain gap between the mounting surfaces of the electromagnetic clutch compressor. If the gap is too large, the impact will also increase. If the gap is too small, there will be motion interference between the electromagnetic clutch and the compressor mounting surface during operation.
