Passenger side heat doesn't work and radiator return hose is cold


Asked by Dec 12, 2015 at 09:33 PM about the 2007 Toyota Camry Hybrid

Question type: Maintenance & Repair

2007 Camry hybrid with 2.4 L synergy drive.  Driver side heat works but
passenger side is cold and the radiator return hose is cold (always). Changed
the thermostat and the water pump but it makes no difference. The car does
not overheat or even run hot. I'm flumoxed.

1 Answer


If you're getting heat on one side, that means it's going into the heater core. I would suspect a bad blend door actuator as for why you cannot get heat to the passenger side. You generally have to remove the glove box and half the dash to replace the actuator.
