Hi, I have a 2013 Dodge Dart SXT 2.0 recently the heater has not been coming on. If I hit the drivers panel it will come on which makes me think it’s the blower motor but my check engine light comes on and when I check the code I get B10EA and B10E9. I’m not sure if it’s the blower motor or the resistor or an electrical issue. Please help because I want to fix it myself if it’s the blower motor or resistor but not sure which part I should buy if I should buy any. Thanks for your help.
