Where is the blend door on a 2000 jeep Cherokee?

The blend door on a 2000 Jeep Cherokee is located inside the dashboard, behind the HVAC system. It's not easily accessible without significant disassembly of the dashboard. There isn't a single easily visible external location. You'll need to remove parts of the dashboard to reach it, typically involving the glovebox, radio, and other trim pieces. Repairing a faulty blend door usually requires specialized knowledge and tools.
