If the vent selector in your 1995 Chevy truck isn't working, it could be due to a faulty control switch, a malfunctioning actuator, or a problem with the vacuum system. First, check the fuses related to the HVAC system. If the fuses are fine, inspect the control switch for any signs of damage. If everything seems intact, the issue may lie in the actuator that directs airflow, which might need to be replaced.
The vent tube could be clogged.
