Mercury Blower Control Switches allow drivers to dial cabin airflow immediately, providing satisfactory results at will. In 1939, Mercury was introduced to American roads and it soon found a niche between bare-bone compacts and luxurious sedans. Represented by the Roman fleet-footed deity, Mercury insisted on automobiles that were easy but comfortable on rough roads. Over decades, the brand continued to refine suspension tuning, expand cabins, and damp road noise so that comfortable cruising became a regular thing. Mercury emphasized spacious interiors in showrooms appealing to families without hurting their wallets. Mercury has straddled the line between value and a touch of attitude since early coupes and then continued into the Grand Marquis flagships, which looked cool parked anywhere. The smooth ride and useful poise the badge provided are also praised by loyal drivers even after production was terminated in 2011. That reputation of balanced comfort made the expectations of all in-cabin components that followed high. Blower Control Switches are placed between the dash knobs and the blower motor that conducts electrical current through stepped resistors to ensure that the fan will spin at a low whisper or at full blast without any hesitation or hiccup, and the tactile clicks of the switch will inform the driver where the air will be directed. Blower Control Switches have long-lasting contacts and transparent detents that can last many years of daily adjustments without shorting the cabin ventilation. Blower Control Switches also make it easier to troubleshoot since only a single modular unit processes all the speed requests. Blower Control Switches also make the heater core and A/C evaporator useful all year-round by allowing the occupants to adjust the amount of conditioned air to them.
