Q: How to remove the Blend Door Actuator on 2008 Toyota Highlander?
A: The first step to remove the Air Inlet Control Servo Motor involves recovering refrigerant from the refrigeration system followed by alignment of front wheels straight ahead. Unfasten the front left wheel and detach the negative battery cable connection while waiting 90 seconds to stop Air Bags from activating. Starting from both left and right sides, bracket the front wiper blade assembly then proceed to uninstall the cowl top ventilator louver sub-assembly, windshield wiper motor and link assembly alongside cowl top outer panel sub-assembly. The maintenance procedure requires removal of heater outlet water hoses together with inlet water hoses and pipe A from the cooler refrigerant liquid along with No. 1 suction pipe from the cooler refrigerant.
