What is the max AC button for?
The Max AC button opens a diverter under the dash that allows airflow to bypass the cabin air filter.
What’s the difference between AC and AC Max?
Max A/C recirculates the inside air. The A/C setting actually mixes a small percentage of outside air in with the inside air. Max A/C will cool the space down quicker, but run for to long and you get stale air syndrome.
When to use Max AC or AC in your car?
With that being said, if it is HOT in your car from sitting in a parking lot all day (10+ hours) — would it get your vehicle cooler if you turn on AC and allow your vehicle to “cool” the outside air being pulled in. OR use MAX AC where the HOT cabin air is just cycled throughout your cabin? Ok, let’s break this down a bit.
What kind of wiring does a car air conditioner use?

The system can maintain a comfortable cabin air condition always when the temperature control dial is set in the vicinity of position 75 (vehicles for US) or position 25 (vehicles for Canada).
How does a motor vehicle air conditioning system work?
Receiver‐Drier send high pressure liquid to expansion valve Receiver Drier will separate liquid from vapor refrigerant Receiver Drier will send liquid refrigerant (high pressure) to the expansion valve Receiver drier will have desiccant bag.
How does a car air conditioner pressure switch work?
by Robert Sylvus. An automotive air conditioner’s pressure switch cycles the vehicle’s compressor on and off when the refrigerant pressure falls below an acceptable level. This protects the compressor from damage. Refrigerant does not wear out or evaporate: only leaking air conditioning systems have low refrigerant levels.
When to turn off the air conditioner pressure switch?
An automotive air conditioner’s pressure switch cycles the vehicle’s compressor on and off when the refrigerant pressure falls below an acceptable level. This protects the compressor from damage.
