2. The heating element is very fragile, so the following precautions should be observed.
- a) Do not leave luggage or other items that may rub against the inside of the glass when the vehicle is in motion.
- b) Do not scratch the spiral elements.
- c) Clean the glass with water and detergent only, and wipe the spiral elements with a soft cloth or chamois.
3. If the element is damaged and no current flows through it, conduction can be restored using conductive paint, contact an auto parts store.
4. Please note that the system draws a very high current, so it is powered through the relay. The switch closes only the circuit of the relay winding, through which power is supplied to the heating element and the control lamp of the switch.
