I have a 2003 Honda Accord ex 4 cylinder blows hot air on the driver side air conditioning but cold air on the passenger please help I was told it was a bad actuator

It definitely sounds like a bad blend door actuator. Do you need a diagram showing how to replace it?

Customer: replied 1 year ago.

Yes please send me the diagram. I also need to know which actuator to change out as I can see three different ones underneath the passenger side and one on underneath the driver side.

It depends on what setting you have the HVAC on. When it blows warm on the driver's side and cold on the passenger side, do you have it set to AC or heat?

Also, is your accord 2 door or 4 door?

Customer: replied 1 year ago.

Yes the AC is running on both driver and passenger sides. I made sure of that.

Customer: replied 1 year ago.

It is 4 door

Here is the diagram that shows both actuators. The one that is likely malfunctioning is the driver's side door on the left of the center console.

However, this condition is most likely caused by an over oiled, undecharged, or faulty AC system.

The system capacity sticker on the 4 door sometimes says 17-19oz of refrigerant. It's not correct- it takes about 1.7lbs (27oz) to get this system to work correctly.

I would make sure the system is fully charged before changing the actuator.

Please let me know if you need any additional information.
