A vehicle’s defrosting system is an absolute necessity for safe driving during the cold winter months. Driving with a frosted windshield or fogged rear window and no way to clear it off can lead to limited visibility and dangerous driving conditions. There are a number of things that can go wrong with the defrosting system ranging from blocked vents to a defective heater core. Front Defroster The front defroster uses the same blower motor, fan and venting system that the heating and air conditioning system use. Air passes through the heater core and then dry air that has been run through the air-conditioning evaporator is added to help remove the moisture from the windshield. All of this air is sent out through the defroster vents on the top of the dashboard. The hot air removes the any snow or ice while the dry air helps eliminate the humidity and fog. Rear Defroster On most vehicles, the rear window has tiny lines going through it, which are electrical wires. These wires heat up as current flows through them. The heat displaces the condensation on the window. These wires produce a very low heat factor so there is no danger of anyone getting burned if they touch the window.

A top-rated mobile mechanic will come to your home or office to determine the source and cause of the defroster system issue, and will then provide a detailed inspection report that includes the scope and cost of the necessary repairs.

A totally or partially defrosted windshield or rear window can seriously affect your visibility, leading to a very dangerous driving situation. Any issues with the defrosting system should be repaired immediately.
