Get your cabin temperature back under control with the Dorman - OE Solutions HVAC Blend Door Actuator 604-020. This small electric actuator drives the HVAC blend door, positioning it to control the mix of warm and cool air routed into the cabin. It's a direct-fit replacement for the 1998-2001 Jeep Cherokee, 1999-2006 Jeep TJ, and 1999-2006 Jeep Wrangler, and it is cataloged for the MAIN position.
- Direct replacement: engineered to install like the original air door actuator on the listed applications and restore proper HVAC operation.
- Position specific: many vehicles use several different HVAC door actuators, so review the application notes to confirm this unit matches the location and function of the actuator you're replacing — this one covers the MAIN position.
- Durable construction: designed and tested to strict standards to help resist wear and electrical burnout for reliable operation and long service life.
- Trustworthy quality: backed by a team of experts and engineers in the United States and more than a century of experience.
If a failed blend door actuator is the cause of inconsistent cabin temperature or a door that won't move, this replaces it.
