The scenario you describe indicates a problem with the blower motor, resistor or corresponding circuit. Instead of throwing parts at the vehicle in an attempt to repair, I suggest having an inspection performed by a certified technician at YourMechanic. Using electronic test equipment, a professional technician will diagnose the problem. This ensures your vehicle is repaired right, the first time.
