This is a strange one. 2012 500c 58k owned since new. When you press the rear defrost button, the check engine light immediately turns on and the ambient temperature read out goes blank. When you turn off the rear defrost, the CEL eventually turns itself off and the temp gauge reads extremely high and then eventually drops back down to normal. This is reproducible every time you select the rear defrost.
Anyone have any ideas?
