Mercury A/C Switch enables quicker comfort on every road trip as it allows drivers to access the cabin climate control instantly without any hassle. Mercury was named after the fleet-footed god and supported it with cars that combined aggressive styling, interior quiet, and a suspension that made long highways seem short. Mercury showrooms applied to be filled with midsize sedans that were not only spacious in their cabins, reducing road sounds, but also provided easy steering that kept day-to-day commuting easy. Mercury continued to roll out comfort-first concepts every decade, demonstrating that value rather than dullness was the way to go. Mercury had this philosophy bundled in commonplace badges such as Cougar and Grand Marquis with known suspension tuning to maintain the sweet spot between feel and cost. A/C Switch can be installed on the dash panel and supplies a clear electrical signal to the climate module and makes the blower motor and compressor clutch know when to turn on precisely when temperature goals have been achieved and frozen. A/C Switch also eliminates run-on, which wastes fuel by terminating the voltage when you open the dial. A/C Switch is universal to the entire brand line, with shared connectors and robust contacts that shake off decades of mouse clicks and weather extremes.
