How to Replace Heater Blower Motor with Fan Cage 2006-2013 Chevrolet Impala

Straight to the point and easy, thanks

IF BLOWER MOTOR GOES, THEY SAY SAY RESISTOR WILL FOLLOW CLOSE BEHIND. I HAVE BOTH PARTS ALREADY, WAS GOING TO RETURN the RESISTOR. REPLACED ONLY BLOWER MOTOR FOR NOW, NOT A BIG JOB. YOUR THOUGHTS ON KEEPING or RETURNING RESISTOR , ANYONE. THANKS
