Check the Blower resistor behind the passenger glove box. I had to replace mine this winter.
There are multiple reasons why the passenger heater on a 2007 Chrysler Pacifica may not work. it could be a heater coil, a fuse, or the blower. A mechanic can help figure out the specific reason.

To replace the heater fuse in a 2007 Chrysler Pacifica, first locate the fuse box, which is typically found under the dashboard on the driver's side or in the engine compartment. Use the diagram on the fuse box cover to identify the specific fuse for the heater. Carefully remove the blown fuse using a fuse puller or a pair of needle-nose pliers, then insert a new fuse of the same amperage in its place. Finally, test the heater to ensure it's functioning properly.
It is inside the HVAC housing, under the dash.

If you are looking for a valve in the heater hoses that restricts coolant flow, it does not have one.
Code P0660 on a 2007 Chrysler Pacifica indicates a problem with the intake manifold heater control circuit. To fix this issue, first, inspect the intake manifold heater relay and associated wiring for damage or corrosion. If the relay is functional, check the intake manifold heater element for continuity and replace it if necessary. Finally, clear the code and test drive the vehicle to ensure the issue is resolved.
