Can't lower the fan speed. And the funny thing is that on the driver side the heater is always on and on the passenger side the A/C won't turn off.

Good evening,

I need to ask you this. When do you command heat, which side is working correctly? That will help determine which blend door motor is not working correctly.

I attached the procedure for replacing them. The right side is easy, but the driver's side requires the removal of the dashboard to access.

As far as the blower speed is concerned, there is a blower module under the right side of the dash. I attached the procedure for you for that as well.

Let me know if you have any other questions.
