Off button sets the mode motor to heat then motor shuts off itself.

You might be able to fix a motor w/ this.
Carefully cut the cover "rivets" to see what is keeping motor on.

Not sure how to attach cover after. Left over "rivets" might keep locating it and just use zip ties to keep it on.

To add...

Are you sure the noise is door motor(s) and not crap in the blower fan?
Check all blower speeds or unplug blower switch or blower up front.

The only time the blower is off is when you push the off button.

The Door Motors will have power even when you push the off button.
Off button means to them:
Recirc door will close. (only open if you push Max AC.)
Mode motor moves to heat mode.
Both motors will shut off their selves when done moving.

I have the problem of switching to vents and nothing comes out I switch to defrost works fine, switch to heater very little comes out how do you fix this I have non AC car

Non-ac car only have 2 cables, no motors, to make the blend doors move. The door and cable to select the mode (defrost, vents, heater) run from the control head to the hvac box right behind the radio.
The door and cable for blending hot and cold run from the control head to behind the passenger dash and terminate at the top of the hvac box where the heater core access panel seam runs.
Check behind the fan and resistors to make sure some of your troubles aren't caused by leaves and nests blocking the air path inside the box. At the very least, pull the resistors panel and clean leaves out before a fire starts!
