Review on HiSport HVAC AC Heater Blower Motor Fan Resistor - 15-81638 15141283 RU-730 Compatible With Cadillac CTS Buick GMC Pontiac Hummer Saturn Chevrolet Silverado 1500 2500 3500 Avalanche by Rusty Heredia

Revainrating 2 out of 5

Does not function properly .

I now have 4 speeds, but they are not in the correct order. 1 is still the lowest and 4 is still the highest, but 2 and 3 are swapped, with 2 being the 3rd position’s fan speed and 3 being the second position’s fan speed. Somehow the resistor is wired incorrectly for the 2nd and 3rd settings.

Pros
  • Part swapped in perfectly and solved my heater control issue
Cons
  • The HiSport HVAC AC Heater Blower Motor Fan Resistor may not be compatible with all vehicle models, leading to difficulties in installation and potential damage to the vehicle's electrical system
