Was wondering if anyone out there is experiencing any ac issues for this 2015 Chevy Trax LS ac. My ac blows but not on the highest setting though. I replaced the blower motor resistor and the pigtail harness connected to it and in less than 24 hours it's all fried up again. Not to sure what to do next.

 

High speed is usually controlled by a relay , so swap out the blower motor relay. Failures in this circuit are typically caused by a worn out motor, so it might be time to change that.
