The Avalon has three servomotors.

First one is on the passenger's side next to the blower-motor behind the glove compartment.
This servomotor moves the air-flap located near the top of the blower-motor to select between external-fresh-air or recycle-cabin-air.

Second one is just below the dash in the middle behind the digital clock.
This servomotor moves the air-flap located near behind the digital clock to select between blowing air on the windshield or blowing air forward into the cabin.

Third one is the DENSO AX063700-5342 servomotor next to the A/C Evaporator and Heater Core, and near the gas pedal.

This servomotor moves the air-flap located near behind the cigarette lighter to select between air blowing through the A/C Evaporator or air blowing through the heater core.

Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

So why would this stop cold air flow to passenger or rear side?
It blows fine, it's just only blows cold on the driver side

this 2007 avalon is equipped with dual climate control to have different temps for driver or passenger. Keep in mind controls do seem to work fine?

The job of the air mix servomotor is to direct cold or hot air and when it is stuck in the hot position, the temperature of the air coming out would not be cool as it goes past the heater instead of the cooling coil.

For dual climate control this often occurs when the servomotor is bad. If you check for trouble codes, you would most likely come to this fault code.

OKAY, thank you it seems like this is what it must be. I have read other blogs
where it was just the opposite drivers side would not cool and they said it was low on freon and it may have been the servo motor also.

So I guess one last question which of the 3 servo motors would this be related to? I'm guessing the third one?

Thank you very much for your help. Mike

I would put that as the passenger side servomotor. To be sure, retrieving the trouble code would be the best way to go about.

I original A/C compressor got knocked and I replaced it with a fairly used one. Also changed the condenser. It worked for about a week and then stopped. I took it to a repair shop and they changed the cooler, it worked for about ten minutes and since then it does not cool any more. All components seems turning when I take a look but not cold air. Please help.

You may have a refrigerant leak, you will have to get the high and low side pressures tested with a suitable 2 gauge A/C manifold set, the readings are a great way to diagnose any problems in the A/C get the readings and report back with the findings.

When my air conditioning stopped working I thought I would be covered by warrenty. Toyota said freeon was low and replaced. The air conditioning worked for a few days then stopped. Following the dye trail the technician said a small pebble caused a hole / leak and this was not under warrenty. COST would be around $1,000.00.
Question: how would a pebble get into the system- the hood was not openned? Is this a design flaw? Is a $1,000.00 repair a reasonable price?
Thanks-

Hi there,

I would be thinking that the condenser has been holes or cracked, this is the most vulnerable section of the system as it is in front of the radiator, it is made of aluminum so its resistance to object striking it is not great(same for all cars) this is not an uncommon thing to see, that is why it is not covered by warranty, as for the cost, it is about what I would expect to see.

What were the readings? You cannot tell freon level by pressure readings
