Will Changing the Car Film Damage the Rear Window Heating Wires?

[LaJoel]

There is a very high probability of damaging the heating wires, but using the correct method to replace the car film will prevent damage to the rear window heating wires. Here are the relevant details: Heating Process: During the replacement, the technician will use a heat gun to warm the film, ensuring it separates from the glass so the old film can be peeled off. If the heating wires are already broken, they cannot be repaired. Important Notes: If the circuit is broken, it will not function properly, and there is no way to repair the broken wires. This means you won't be able to defog the window when needed. Although you might only use this feature a few times a year, if the wires are broken, you should stop using them and avoid attempting repairs—simply replace them instead.
