Nice to meet you all.
I'm riding a 2003 H2.
I love American cars
Get a driver's license
Riding the 1996 suburban for 7 years
I switched to H2 10 years ago.
There is a problem with the air conditioner since last year.
To an American car repair shop in Japan
I left it for 6 months, but it didn't heal.
My children are also shocked.
I was looking forward to riding the H2 and going for a drive with my family.

At the repair shop
With air conditioner control panel
I replaced 4 actuators
Only warm air comes out on the passenger side.
It cost a lot of money.

Because it ’s difficult to pay more money
Try to repair yourself as much as possible
I thought.
I was in trouble with the locals in America
To cooperate
I registered for the Hummer Forum.
Thank you for your cooperation.

Is there a cause that comes to mind?
Please tell me the teachers of American cars.

I only understand a little English
While looking up on translation sites and dictionaries
I wrote this sentence.

I think it's hard to understand.
I'm sorry.

your refrigerant levels might be low. it can cause the issue you are experiencing. cold one side hot the other.

thank you for your answer.
The amount and pressure of refrigerant gas, etc.
You may need to check it, right?

 

Cold one side, hot other is almost always blend actuator problem. Maybe the wrong one replaced or not calibrated?

 

The actuator under the passenger seat side
Ticking ticking
The sound is ringing all the time

More than the range of motion of the actuator
Is the motor running?
For some reason
Does the flap not move?

 

Ticking actuator is failed with broken gear usually. That will cause the problem you have.

 

Currently, the area around the dash panel is being disassembled. I think the four actuators are working fine, but when I diagnose them with a gm tester, I get an error code that says the passenger seat temperature sensor is malfunctioning or malfunctioning. Is there a possibility that the indoor temperature sensor is defective?

 

can you post the specific code?
it will help us with diagnosis

does the drivers side cool like it should?

when the actuator was replaced it needed to be installed correctly for the blend door to work correctly. With a GM scanner you should be able to verify the position of the doors and see if the position is changing with input and also correctly calibrate them if they are working/installed correctly.
