I disconnected my battery last week, had to reset the HVAC and exterior temp displays from C to F afterwards, and didn't think anything of it at the time. However, most of the times that I've started the car since then, the display has reverted to Celsius. I've double-checked the battery connections for snugness, the car starts up fine every time, but I've had to change the display back to Fahrenheit almost every time. Ultimately, I don't care what units are displayed, but I'd like to know the reason for this and if it might be a symptom of a bigger problem, especially since I've been having electrical issues of late.

are procedures there. Disconnecting the battery has nothing to do with it since the control module obviously was coded for C.

Sounds like a flakey ground
