Back again! Hey guys and good morning, just a simple question that I been pondering and would hopefully get my answear from my civic buddys . Soo ok, the sider for ac is at hot and I begin to turn it on. Now, once its on, the sound started to make which it is on the passenger side. I don't know if my ac or coolant is messed up but why is there sound when I turn my ac on? But later on it stop. Just irritates me, that's all.

 

It would be hard to figure out what you are talking about without a video. Try and get a video going so we can hear the sound exactly.

However, by the way you are describing it, it sounds like your blower motor.

 

Post a clip/video of the sound.

LOL sorry no video camera, going to get one soon but anyway, it sound like a flow of jet stream you know? or a wet nos sound which I don't have.

 

Well, are you sure that no one installed the wet kit when you weren't looking? haha

Is the noise made when you turn the climate control on (i.e. heat, a/c etc), or ONLY when you hit the A/c button?

 

ahaha I hope not 0_o, only when I swtich the A/C fan to number 1 level to blast heat out.

 

Starting with the 1996 model (I think), the A/C will engage whenever the air outlet control is on defrost. It will do that whenever the outdoor temperature is warmer than about 35 whether or not the A/C button is pressed. Sometimes it is normal to hear refrigerant flowing in the evaporator behind the dash. It sounds like a hissing or gurgling.

 

There also may be some leaves or debris stuck inside the blower. You can take out the blower motor by removing three screws behind the glove box.
