GMC Terrain A/C Switch places the driver in control of interior comfort. Sending precise commands to the climate control module, the switch lets cool or warm air arrive when it is wanted. Early GMC models had simple buttons or knobs that closed a relay to start or stop the compressor and blower. Newer designs have the A/C Switch on a small keypad inside the automatic climate module where one tap generates digital signals to a power module that changes blower speed in countless steps based on cabin and outside temperature data. Though both A/C Switch versions aim at the same thing, the latter one restricts any unnecessary use of the compressor, which saves fuel and reduces wear. A stuck relay can keep the system on or off, meaning a reluctant fan or dead button often points first to the A/C Switch, not expensive hardware for your HVAC systems. Across the GMC lineup, the compact Terrain puts the switch in a convenient spot in the center stack. Every GMC Terrain relies on a 12-volt control circuit, making it easy to replace a failed A/C Switch with a replacement for the appropriate Terrain trim and keep the cabin air a pleasant place to be all year round.
