Why is my Subaru auto air system overcharging?

Answer by  garymarkle (599)

Your system may be over charging because you have too much of the chemical freon in your system or in the pump intself, you could also have a blockage in the lines of your auto system. Excess freon can be bled off, however, I would check with your auto mechanic.

Either you have a blockage somewhere in your coolant system, or maybe have it has air locked and the coolant system might just need bled of air

I can only assume you are talking about the A/C system. The only way for it to over-charge is if someone has added too much r-134 air coolant to it.

It can be due to too much freons in the system or there might be a blockage somewhere. You should check with your mechanic to make sure it is not a computer related issue.

You have a problem with your humidity sensor, which is probably kicking the air conditioner into autodrive even though normal levels are present. The humidity sensor is a basic part that you can order through your dealer for about $35. It's going to be tough to put the part in yourself, you're better off hiring a professional.

Too much load of freon gas. Your setting is at the coolest. Now, finally, Subaru has a good working AC compressor.
