I have a 2002 astro van that the defrost blower and heat work but the cabin heater does not blow?

Are you saying the air only blows out the defrost?

Thank you for your reply. Yes, the air only blows out of the defrost, but the rear heater does work. Could it be a vacuum hose not opening the main vents?

Yes, it could be a vacuum issue or the mode actuator. Note diagram.

Thank you for your response, could you tell me where the actuator is physically located on the van? Thanks again.

It's under the dash. I'd have to look. Below is the best picture I have.
