hey guys. usually I can ready older threads and fix my issues but I need help with this one. My fan is not working. It used to work and went out a couple months ago. I pulled the connector to the blower motor and tested it for power. None. I checked the #9 fuse and it was good. I swapped it with another 30 amp fuse to double check. Still no power at the connector to the blower motor. Then i ran power direct to the connector end that goes to the blower and grounded it - fan spun. I changed the control switch in the cab to low from high but it didn't change the speed. i pulled out the fan control switch and checked for power there - nothing. so I need power. where/what should I be checking?
