The temperature actuator for the passenger side on a 2003 Chevy Silverado is located behind the dashboard, specifically behind the glove compartment. To access it, you typically need to remove the glove box and possibly some surrounding panels. The actuator is part of the HVAC system and controls the temperature blend for the passenger side. Make sure to disconnect the battery before attempting any repairs to avoid electrical issues.
On a 2003 Chevy S10, the blend door actuator is typically located behind the dashboard, near the heater core and blend door assembly. To access it, you may need to remove the lower dash panel and possibly the center console, depending on the specific configuration. The actuator is usually mounted on the HVAC housing, and it controls the flow of air between the heater and air conditioning systems.

Well, honey, the vacuum line on a 2003 Chevy Silverado 2500HD is typically located near the intake manifold or throttle body. You might want to grab a flashlight and get down and dirty under the hood to track it down. And remember, if in doubt, consult your vehicle's manual or a professional mechanic before you start yanking things apart.
over time the vacuum lines can get clogged with gunk and not allow the actuators to engage the trans axle, so replace all the vacuum lines and if it still doesn't work its probably a bad actuator or the motor on top of the transmission.
don gory. me help yu
does anyone know where the sparkplugs are located on the engine on a 2003 Chevy trailblazer
No
I believe it is located behind the glove compartment. Drop out the glove compartment box and you will see the blend door actuator.
