Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
i am getting no air flow when i turn on the heat or air. I checked all of the fuses and they look good. As far as the controls and all light up when you push a certain function like a/c and you can tell when you switch the which way the air flows like from the windshield to the dash. You can hear it switch over. but like i said im getting no air flow what so ever

Check for 12 volts DC at blower motor connector with the switch on the highest speed. If you have 12 vdc at the connector your blower motor needs to be replaced.
how do i know which connection there is? There are like four or five of them connecting into the blower motor
