The temp door actuator is on the top right hand side of the heater vent module. You might be able to see it from behind the glove box, but you have to remove the dash to service it. Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

That's not a blend door problem. That's a mode door problem. The mode door actuator and linkage are on the left side of the HVAC housing, on the end. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.
