AS WITH ALL MY VIDEOS I TRY TO GIVE THE MOST INFORMATION IN THE LEAST AMOUNT OF TIME AS POSSIBLE SO I DON'T WASTE YOUR TIME. IN THIS VIDEO THE BLOWER MOTOR STOPPED RUNNING ON THE VEHICLE MAKING THE A/C OR HEATER NOT WORK ON A 2011 MERCURY GRAND MARQUIS. I GO OVER HOW TO DIAGNOSE EITHER A BAD MOTOR OR BLOWER MOTOR RESISTOR USING A BASIC MULTI-METER. I DO AN OVERVIEW OF HOW TO REPLACE THE BLOWER MOTOR IF IT IS BAD OR IN MY CASE THE BLOWER MOTOR RESISTOR WAS BAD AND I GO OVER HOW TO REPLACE IT.
