I have a 07 IS350 with 33k miles. Recently I noticed that the a/c would be fluctuating in air flow. When on full blast, the a/c will randomly drop down to very low air flow and go back. Also the highest setting is not as strong as it use to be. Is it time for an a/c fluid flush?

 

Do you have the A/C auto feature on? That may be the problem.

 

LOL, AC fluid.... Your AC runs on refrigerant, which is a gas. Was your car recently in an accident?

 

If it's an airflow problem then I would check the blower fan or perhaps you have the system set on auto which in case will cause it to do that.

 

is there a different in how cold the ac blows or just the strength

 

It was not on. I guess I will take the car into the dealership. Gotta do a few routine maintenance soon.

 

i was trying not to be a jerk, but i was thinking the same thing lol

To the OP, i would take it in and have the dealer look at it just to be safe. i was thinking the auto feature at first but its not that dramatic of a change even with the auto feature on
