Heated/Cooled Cup Holder Description and Operation
The Heated/Cooled cup holder system uses a positive temperature coefficient (PTC) ceramic element. The PTC is attached to the side of an aluminum
cylinder that forms the cup holder to provide the temperature change. B+ will either heat or cool the PTC element in the cup holder. Voltage applied in
one direction heats the element and cools it when the polarity is reversed. A momentary switch on the console surface operates the unit. It offers off, heat
and cool settings. The cup holders have a temperature range that heats to 140°F or cools to 35°F. A light in the switch glows red to indicate heating and
blue to indicate cooling.
