Is LO on seat heating for cold air?
3 Answers
LO on seat heating does not indicate cold air; it refers to the low-level heating setting. Below are specific details about seat heating: 1. Structure: The lower layer of the seat heater consists of a non-woven fabric. Heating wires are arranged on this fabric and secured with adhesive tape. A knitted fabric covers the adhesive tape and is stitched with knitting thread into a shape resembling the heated area of the seat, then sewn into the seat cover. 2. Principle: To enhance passenger comfort and maintain seat heating temperature within a certain range, two temperature controllers are installed in the heating pad. The backrest heater connects to the seat cushion heater power supply via a connector, which in turn links to the dashboard wiring harness through another connector. This circuit then passes through the seat heating switch, fuse, and ignition switch to connect to the vehicle's battery power.
I remember one winter while driving, I turned on the Lo setting for seat heating, which is the low-temperature heating mode, definitely not cold air. The Lo setting means low speed or low-temperature heating, allowing the seat to warm up gradually, unlike the Hi setting which can get quite hot. Cold air comes from the air conditioning system's fan blowing cool air, but seat heating only relies on electric heating wires to warm the seat surface and doesn't blow any air. Some friends might accidentally press the wrong button or confuse the icons; it's advisable to check the button icons near the steering wheel—usually, it's a heating symbol, not an air conditioning symbol. In daily use, the Lo setting is quite practical for mild weather or short drives, being both energy-efficient and avoiding overheating discomfort. Overall, the seat heating function is focused on providing warmth and has nothing to do with cold air—don't get them mixed up.
As someone who has worked on cars for many years, I can definitively say that the Lo setting for seat heating is part of the heating function and has nothing to do with cold air. Lo represents a low-voltage state where the heating element produces gentle warmth to raise the seat temperature, while cold air is delivered by the air conditioning compressor and duct system. If it feels like cold air, it might be due to an electrical issue such as a blown fuse or loose connection causing the heating to fail, while the air conditioning is blowing air, creating confusion in perception. The correct procedure is to first check the status of the heating button and avoid prolonged use to prevent wiring degradation and safety risks. Simply put, the goal of seat heating is to warm you up, not to cool you down.
