I replace windshields for my dealership. The newer Tundra's have heated and non heated options. Besides the wires that plug in for the heated windshield there is no difference. I see that both heated and non heated have the plugin for the heater option below the cowling. If you replce the heated windshield with a non heated one, is there any problems that will occur? Also, can you put a heated windshield into a vehicle that came without it since the the plugin is there and appears fully functional.
