Defrost lines on a rear windshield are a series of wires embedded in the glass, used to free accumulated ice on the rear windshield.
The components are electrically conductive wires embedded in the glass of a windshield or rear window of vehicles mainly driven in cold areas.
Drivers use them to improve visibility and safety as frost and ice blur the windshields.
These wires are typically connected to a button or switch on a vehicle's dashboard. When activated, they generate heat that melts ice or frost.
The heat is distributed evenly across the glass surface, ensuring that all windshield or rear window areas are covered.
What Do When Defrost Lines Fail To Activate
Check the switch: Ensure the switch or button that controls the defrost line is working properly. If it's not, the defrost line won't activate.
Check the wiring: Inspect the wiring that connects the switch to the defrost line to ensure it's not damaged or disconnected. If there is damage or disconnection, it may need to be repaired or replaced.
Check the fuse: There may be a fuse that controls the defrost line, so check to see if it's blown. If it is, replace it with a new fuse of the same amperage.
Check for damage to the defrost line: Inspect the defrost line for any damage, such as breaks or wires. If there is damage, it may need to be repaired or replaced.
If none of these solutions works, taking your vehicle to a mechanic or auto glass specialist may be necessary for further inspection and repair.
Defrost technology is hardly used on local vehicles that are driven in areas that experience a tropical climate with distinct wet and dry seasons.
The local weather conditions vary across the country due to differences in altitude, topography, and proximity to the coast.
However, a little frost is likely to occur on cars that are parked in low-temperature areas such as Mount Kenya, especially, during the long rainy season.
