My 2017 has been in the shop for ~10 days now and nobody can figure out how to solve this problem. The blower motor will be delayed to start by 5-10 minutes the first time you start it in the morning (or after it sits for 8 hours or so - for both AC and Heat). So far they have replaced the motor itelf, the module (I'm guessing the engine control module? - they just said module), the switch, a temp sensor, and the resistor pack, and it continues to do this. The service department said that they opened a STAR case a few days ago so hopefully someone at chrysler knows whats going on. Does anyone here have any idea what might be going on?
