Re: Vent controls dont work
You have an actuator that moves linkages, and a dash controller that powers the actuator.
Any part of it can be a problem.
You will need to do some investigation and logical thinking to figure it out.
Does the actuator move?
Is the linkage binding?
Is the control unit trying to power the actuator?
Then some testing to determine WHY.
A wiring diagram, a voltmeter, a service manual.....
Or play swaptronics if you have another car to rob parts from.
