My 2013 Dodge Dart Rallye 1.4L has recently been experiencing issues with the AC working intermittently. When I start my car the AC will turn on 70% of the time and work without any problems (no audible indications that the blower is going, full air on each setting). The other 30% of the time it will not blow air at all no matter what setting it is on. However, sometimes when it doesn't work it will magically start working 10 or more minutes into the drive. I'm trying to figure out if this is more likely a blower motor issue, a bad blower motor resistor, or something else?

Auto temp control? Possibly a problem with the ambient air temp sensor. There should be codes if you can get alfaOBD.

Without codes we are just guessing. There is an HVAC module on top of the heater box, wiring, a blower motor control module right next to the blower motor, or the blower motor.
