Dorman 604-191 HVAC Air Door Actuator Temperature Left Side

The Dorman 604-191 is a direct-replacement HVAC air door actuator designed to restore proper temperature control to the left side of your vehicle's climate control system. This temperature blend door actuator controls the mix of hot and cold air delivered to the cabin, and a failed unit can result in loss of heat, air conditioning, or the inability to regulate interior temperature on one side of the vehicle.

Dorman engineers this actuator as a position-specific replacement, precisely matched to the fit and function of the original equipment part it replaces. Because most modern vehicles are equipped with multiple HVAC actuators — each assigned to a distinct location and function — it is important to verify that this part corresponds to the left-side temperature actuator position in your specific application.

Key Features:

• Direct OE Replacement — engineered to match the fit and function of the original actuator for a straightforward installation
• Temperature Control, Left Side — specifically designed for the left-side temperature blend door position in the HVAC system
• Durable Construction — designed and tested to resist wear and electrical burnout for long-term, reliable operation
• Position Specific — verify application notes to confirm this part matches the exact location and function required
• Trusted Quality — backed by Dorman's team of U.S.-based engineers and over a century of automotive aftermarket experience

The Dorman 604-191 is part of Dorman's extensive HVAC actuator lineup, one of the most comprehensive offerings in the aftermarket. Always confirm the correct actuator position for your vehicle before installation to ensure proper fit and function.
