Im not sure what is wrong with it, has never happened before. I got my oil changed today and i was on the highway and the heat light started to blink then it stayed on but the heat gauge was normal, something wrong i should know about? im new to the rotary world. i was just wondering. id go over a bump and it would fliker. i even checked and pulled over and made sure the motor was not leaking anything. can anyone help? this is weird.
