This just started probably about a month ago. For some reason the drivers side cooling seat comes on. Sometimes it's random and just comes on. Most times it comes on when you touch any button that gas to do with the climate control. The heated seat doesn't come on though. It won't even light up. The passenger side works as it should. I bought another control assembly from Ebay and it does the same thing. I've eliminated the actual seat as a problem because I disconnected it and the buttons still do the same thing where only the cooling lights come on and not the heat. I can't seem to find any other info out there that has a similar problem.
