ive been upgrading car audio in my 2001 RX300 and now the center two vent that blow towards your face dont work...like the HU may not be telling the inner divider to adjust? need help..

 

I would start by checking the work you have done to see if it caused the problem.

It just might be a coincidence that the air damper control (servo) module may have gone bad ... You should be hearing a constant clicking from the area below the glove box.

DO a search. If I find it, I will edit this post and add it here.

im pretty sure i cut the vent oscillator wire...or pinched it, but dont know where to find it

 

anyone know what the problem is?

 

Have you traced the wire from the motor back or even check for voltage?

We will be all shooting in the dark ..
