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.
