Just bought 2012 Mazda5GT black/black
 

Been eyeing this a long time to replace a quest I sold several years ago. Got a grand touring today, very nice shape. Has anyone ever noticed a difference in how warm the driver seat gets versus the passenger seat? I have sat in both, the driver seat clearly is warmer. Should I try swapping the control switchs? manual says to test switchs and replace but nothing about the warmers ever needing replacment
