I'm guessing 70-72 are the same but there are differences. I have a A/C car. I finally got my blower motor to work however it runs on all settings. My A/C horizontal A/C control is in the off position. The vertical switch is in the off position ( all the way up) The motor is still running on low speed, same speed an the slowest. Is this correct or is my switch faulty and not sutting off. I disconnected the A/C switch plug and it still ran so I know it's not that switch.

Those vehicles are equipped with a ventilation system that the fan runs on low speed always to get good airflow through the cabin.

People fear change because it threatens what they know, or what they claim to know.
