hvac blower doesn't work , fuses all check ok
Have you check the relay and selector switch ?
Most common is the blower motor resistor that goes bad. But first you would want to run a separate power line to the blower motor to make sure it works. Another thing that happens is the blower motor looses ground, it is mounted in plastic, may have to run a separate ground wire to the blower motor.
One day it was working fine, shut engine off and when I started it again the blower wouldn't work. . the next day blower worked fine. 2 days later blower quit working as I was driving and hasn't worked since !
First thing to check is the blower. jumper 12v to the terminal on the motor to verify that it is not the problem...it could be as simple as a bad ground
